FBC Compatibility FIP Bus Controller version 3 or later is required for this CPU. Power Supply Compatibility and Requirements A CPU374 requires the use of a High Capacity Power Supply (IC693PWR330, IC693PWR331 or IC693PWR332). Power consumptions of the CPU374 and its supporting devices are listed below:  CPU374 requires 1.48A @ +5VDC (= 7.4 Watts).  If used, the converter in the IC690ACC901 serial cable assembly adds 100mA at 5VDC (=0.5 Watts).  If used, the IC690ACC900 RS-422/RS-485 to RS-232 converter adds 170 mA at 5 VDC (=0.85 Watts). IC693ALG220/221 Analog Input Module Version Requirements Series 90-30 CPUs 35x/36x/37x are not compatible with versions F and earlier of the IC693ALG220/221 Analog Input Modules. Version G or later of the IC693ALG220/221 must be used with these CPUs. If a version F or earlier IC693ALG220/221 module is used with a 35x/36x/37x CPU, the %AI values reported by the module may exhibit erratic behavior. IC693PBM200 PROFIBUS Master Module Version Requirements All IC693PBM200 modules used with a CPU374 must be updated to firmware version 1.16 or later. When earlier IC693PBM200 versions are used with CPU374, backplane communications errors and PLC faults occur frequently while the CPU is in RUN mode. IC693PBS201 PROFIBUS Slave Module Version Requirements All IC693PBS201 modules used with a CPU374 must be updated to firmware version 1.28.1 or later. Earlier IC693PBS201 versions have issues similar to IC693PBM200 versions earlier than 1.16. PPDD Compatibility The PLC Program Download Device, IC690ACC990-BC, is fully compatible with the CPU374/372 PLUS. Ethernet Functional Compatibility Subject Description Programmer Version Requirements Proficy Machine Edition Logic Developer PLC 5.6 SIM 7 or later must be used to use Modbus TCP or to utilize the less restrictive sub-network mask. Proficy Machine Edition Logic Developer PLC 5.0 Service Pack 3 Hot Fix 3 or later must be used to configure Web Server support or to enable EGD Signatures. CIMPLICITY® Plant Edition Version Requirements CIMPLICITY Plant Edition 6.1 Service Pack 1a with Update 040204_s90tcp_6101 or Service Pack 2 or later must be used for Ethernet communications with CPU374 Release 12.0 or greater. Name Resolution Unlike the CPU364 (IC693CPU364), the CPU374 PLUS does not support Name Resolution. AAUI Port Unlike the CPU364, the CPU374 PLUS does not have an AAUI Port. Series 90-30 CPU 5 GFK-2123Y Ethernet Problems Resolved by Firmware Version 6.13 Subject Description Addresses product security issues Ethernet Firmware version 6.13 addresses product security issues identified as Security Advisory GEIP12-08 in Security Advisory document KB14607 (http://support.ge-ip.com/support/index?page=kbchannel&id=S:KB14607). TTL Value resets to 255 after power cycle When TTL value is configured using AUP file in configuration download, then after system is restarted, TTL value resets to 255. CPU Restrictions and Open Issues Subject Description Power supply serial port does not respond to SNP/SNPX requests The Power Supply Serial Port does not respond to SNP or SNPX requests that include the break character if:  an Attach message is received that is missing the last character before the Block Check Code (BCC),  a message is received that has an invalid BCC or is corrupted so the calculated BCC doesn’t match the BCC specified in the message. Power to the CPU must be cycled to regain communications. Serial communication at 1200 Baud A break-free SNP serial connection at 1200 baud may fail occasionally. If failures are observed, users should choose a higher baud rate. Programmer communications are not affected by this problem. Call to Service Request 24 may need to be repeated As expected, a Loss of, or missing option module fault is always recorded in the PLC fault table when using SVC REQ #24 to reset an IO module. However, the CPU374 does not always record the corresponding Reset of, addition of, or extra option module. Instead, this fault occurs every other execution of SVC #24 rather than every execution. Using an invalid System ID for the EGD command COMMREQ produces no faults Using an invalid value for the System ID of a COMMREQ for EGD commands results in the COMMREQ running with no indication of failure. The command appears to be properly initiated even though it did not execute due to the invalid System ID. CPU374 PLUS warm restart time exceeds 5 seconds CPU374 PLUS power-up time takes longer than 5 seconds from the time when power is applied until logic begins execution and I/O is written by the CPU. Module hardware fault is logged for PCM301 Module hardware fault is logged for Programmable Coprocessor module PCM301 in main rack after successive series of power cycles. But the module and its LEDs operate as expected even after logging the fault. Fault is not logged for extra CMM and HSC module in the rack When a configuration with just a power supply and a CPU374+ is downloaded to a CPU374+ with HSC, CMM or both modules present in the rack, no extra module or addition of module fault(s) are logged. Ethernet Restrictions and Open Issues Subject Description SRTP connections remain open after IP address changed The Ethernet Interface does not terminate all open SRTP connections before changing its IP address. Once the local IP address has changed, any existing open TCP connections are unable to normally terminate. This can leave SRTP connections open until their underlying TCP connections time out. If quicker recovery of the SRTP connection is needed, modify the wkal_idle Advanced User Parameter to reduce the TCP keep alive timer down to the desired maximum time for holding open the broken connection. Refer to TCP/IP Ethernet for Series 90-30 CPU372/CPU374 PLUS User's Manual, GFK-2382 for details. 6 Series 90-30 CPU GFK-2123Y Subject Description Reduced EGD consumption with large numbers of produced exchanges When large numbers of EGD exchanges are produced at a rapid rate, some consumed EGD exchanges may exhibit lower rates of consumption than expected. To better balance produced and consumed EGD exchange performance, reduce the number or frequency of the produced exchanges configured at this Ethernet Interface. Spurious ‘Ethernet Failure’ error On rare occasions, the error Module hardware fault may be reported on the Ethernet daughterboard. The corresponding fault in the exception log is Event = 1, followed by text Ethernet failure. This fault is a nuisance fault and may be ignored. Spurious Ethernet fault In rare instances, after power cycle, the Ethernet Interface may log the following fault, Event = 28H, Entry 2 = 000eH. This fault can be safely ignored. EGD command passwords are not supported. Optional passwords are not allowed within EGD Command COMMREQs. EGD command range failure can write partial data to plc bit memory When an EGD Command attempts a write operation to a bit-mode PLC reference memory range (%I, %Q; %T, %M, %SA, %SB, %SC) where the amount of data be written exceeds the configured size of that reference memory, the command will return failure status but partial data may be written into the reference memory. The amount of partial data written depends upon the starting bit memory location and the data length as follows:  If data starts on a byte boundary (location = (8*n) + 1), no partial data is written.  If data does not start on a byte boundary (location = (8*n)+1) and data exceeds the configured reference memory by 8 or more bits, partial data is written from the starting location to the next byte boundary after the starting location.  If data does not start on a byte boundary (location = (8*n)+1) and data exceeds the configured reference memory by less than 8 bits, partial data is written from the stating location to the end of configured reference memory. For a Write PLC Memory command, this can occur when writing data into the target PLC. For Read PLC Memory or Read Exchange commands, this can occur when writing data received from the target PLC into the local PLC memory. The logic application must not use any data returned to the local PLC if the EGD command status indicates failure. To avoid writing partial data to the local or remote PLC, be sure that bit memory data transfers do not exceed the configured reference memory sizes at the appropriate PLC. Producer ID of zero in capabilities response Producer ID is set to zero in the EGD Capabilities response if the IP address is set up by the setIP utility. Afterwards, any subsequent Hardware Configuration store will have the producer ID reported correctly. EGD I/O has unexpected variability under heavy load EGD I/O has intermittent unexpected variability under heavy load. For a Produced Exchange, EGD samples may occasionally be delayed by as much as a production period. Clear of large hardware configurations may cause log event 08/20 A Log event 08/20 may occur when very large hardware configurations are cleared and transfers are active on other Server connections. This log event can be safely ignored. Station Manager PING commands When initiating ICMP echo requests from the PLC via Station Manager’s PING command, the operation occasionally fails and an exception is logged (Event 0eH, Entry 2 = 06h). Web server failure under heavy load After several hours of heavy load on the web server, the web server may fail to return pages and may cause a LAN system-software fault to be logged. The web server will resume serving pages when the load is reduced. EGD production is inactive after a Stop-Store of configuration When upgrading from a CPU364 to a CPU374 PLUS, sometimes EGD does not start correctly when transitioning from Stop to Run mode. To avoid this problem, you should choose not to keep the common parameters when replacing the module. This will require you to configure the CPU374 PLUS from the default settings. Series 90-30 CPU 7 GFK-2123Y Subject Description AUP file with invalid first line causes failure during store to PLC For the CPU374/372 PLUS, the first line of the AUP file must always be AUP_0_1. If the first line is incorrect, the PLC rejects the file when it is downloaded from the programmer. This causes the programmer to abort the store, with a report in the feedback window of Error 8097: Controller Error – Invalid input parameter in request. The PLC logs a fault with Group 129: No User Program present. After one minute, the Ethernet logs a fault (Event 02h, Entry 2 = 07h) to indicate a timeout during configuration. If the configuration included EGD exchanges, there will be an additional log entry for each exchange (Event 28h, Entry 2 = 09h). AUP parameters that specify a UDP port number do not reject a value of 0 The Advanced User Parameters that specify a UDP port number include gdata_port, gctl_port, and gXX_udp. The Ethernet firmware allows these parameters to be set to 0, and no faults are logged if they are set to 0. However, the correct lower limit for the UDP port number is 1. The firmware and the documentation need to be revised accordingly. CPU Operational Notes Subject Description Supported Features Some features that are shown in the Machine Edition configuration for the CPU374 PLUS are not supported on the older versions. This includes features like Modbus. While the configuration remains backward compatible with older CPU374s, new features are not allowed on older versions. Thus the latest version should be used when the newer features are desired. Battery Backup Limitations The expected life of a standard Series 90-30 3-volt lithium battery used to back up a CPU374 is 1.2 months when used continuously. If a longer battery backup period is required, the external battery module (IC693ACC302) is available. The extended battery module provides a nominal battery backup period of 15 months for the CPU374. See GFK-2124 for additional information. Overrides Not Stored to Flash or EZ Program Store Device When storing reference data to flash or the EZ Program Store Device, overrides are not stored. This means that after the reference data is read back from flash or the EZ Program Store Device and subsequently the PLC is put into Run Mode, the logic may execute differently. Therefore, overrides should not be used if reference data is stored to flash or to the EZ Program Store Device. If overrides are used, particular care should be taken to prevent loading reference data from flash at power up. If this precaution is not observed, unexpected operation may occur upon power cycle. Writing Flash Using a Serial Programmer When writing very large programs to flash memory, you may need to increase the request timeout value in the programming software to avoid receiving a request timeout message. An upper bound of 25 seconds is typically satisfactory. For further details, see the Ethernet Operational Notes item Store of Program or Reference Tables to Flash may Cause Loss of Ethernet Communications on page 11. Storing Large Configurations A Series 90-30 PLC using a CPU374 supports a maximum of 32 DSM314 modules. This number is reduced when other intelligent modules are used in the PLC, such as APM and GBC modules. It may also be reduced when:  The number of racks in the PLC increases;  The total size of logic, motion and AUP files increases;  The application uses C logic blocks or a C logic program; and  Connected programmers or HMI devices are used to read reference memory or fault tables. In some cases it may be possible to increase the number of DSM314 modules that the CPU374 will accept in the hardware configuration by storing logic first and then storing the configuration separately. 8 Series 90-30 CPU GFK-2123Y Subject Description Simultaneous Load and Store When operating with multiple programmers attached, initiating a store operation from one programmer during a load operation from another programmer will cause the load to fail. Transition Tables are not cleared when the reference tables are cleared The transition tables are not cleared upon clearing the reference tables through the programmer. Upgrading Firmware with Many Modules in Rack The process of upgrading the PLC firmware with the WinLoader utility may fail when multiple IO modules are in the main, remote or expansion racks, due to the extra time it takes to restart the PLC CPU. If the upgrade process fails, wait until the OK LED on the power supply stops blinking and then click the Retry button on the WinLoader Firmware Update Failed dialog box. If the upgrade fails again, move the PLC CPU to a rack without IO modules and restart the upgrade process. Auto-baud Feature Not Supported The serial auto-baud feature, intended to allow a serial connection at lower baud rates than the default 19.2K, is not supported on the CPU374. If the user desires a connection at a non-default baud rate, the proper configuration should first be stored to the PLC. COMMREQs are not supported to Rack 0 Slot 15 Task 0 The CPU36X supports sending COMMREQs to the daughtercard by sending the COMMREQs to Rack 0 Slot 15 Task 0. The CPU37x line of CPUs does not support these COMMREQs. COMMREQs should instead be addressed to Rack 0 Slot 1 and the appropriate Task. For additional information, refer to the TCP/IP Ethernet for Series 90-30 CPU372/CPU374 PLUS User's Manual, GFK- 2382. Fault is not logged if power cycling is done when using the portable download device to transfer to the PLC Power should not be cycled when performing operations with the portable download device. Cycling power can result in the downloaded data not being properly stored, which will cause the PLC to clear the memory on power-up. 90-30 High Speed Counter may be lost over multiple successive power cycles. The 90-30 HSC module may not complete its initialization and set its module ready bit after a series of power cycles in close succession. Upon failure the module needs to be reset or the rack needs to be power cycled once more. Ethernet Operational Notes Subject Description Remote Station Manager access is disabled until Station manager password is changed User should change the station manager password to other than the default password. The remote station manager access is disabled until the station manager password is changed to other than the default password. The station manager password can be changed using an AUP file. (Refer to Appendix A, Configuring Advanced User Parameters in TCP/IP Ethernet Communications for PACSystems User’s Manual, GFK-2224K.) One TTL value configuration for all EGD groups The system accepts only one TTL value configuration. If you configure separate TTL values for each EGD group, the minimum TTL value will be configured for all EGD groups. Protection against attack on FTP Server When FTP connections and/or Web Server Connections are not in use, the configuration of number of FTP server connections and/or number of Web server connections should be set to 0. This protects against attack on FTP Server. The configuration for the Max number of FTP Server Connections and Max number of Web Server Connections can be found in the Ethernet tab of the CPU configuration screen in Proficy Machine Edition. Ethernet Interface Functionality Changed For releases 12.0 and later of the CPU374, the Ethernet Interface functionality has been changed to more closely align with the PACSystems Ethernet Interface functionality. Functionality affected includes station manager commands. Functionality affecting application and protocol behavior has not been changed. For details, see TCP/IP Ethernet for Series 90-30 CPU372/CPU374 PLUS User's Manual, GFK-2382. Series 90-30 CPU 9 GFK-2123Y Subject Description Configuration of IP Address is Required Before Using Ethernet Communications The Ethernet Interface within the CPU module cannot operate on a network until a valid IP address is configured. The necessary Ethernet addressing information must be configured prior to actual network operation, or to recover from inadvertent changes to the Ethernet addressing data at the Ethernet Interface. Use one of the following methods to initially assign an IP address:  Connect a serial terminal to the Station Manager port of the PLC. Then use the CHSOSW command to enter the desired IP address. For details, see the TCP/IP Ethernet for Series 90-30 CPU372/CPU374 PLUS Station Manager Manual, GFK-2383.  Temporarily assign an IP address to the module using the SetIP tool over the Ethernet network. For details, see TCP/IP Ethernet for Series 90-30 CPU372/CPU374 PLUS User's Manual, GFK-2382. Once a temporary IP address has been set up, the Ethernet Interface can be accessed over the network (such as by the Machine Edition programming software). The programmer should then be used to configure the proper IP address for the Ethernet Interface. LAN Must be Tree, Not Ring The two Ethernet network ports on the Ethernet Interface must not be connected, directly or indirectly, to the same network device. The hub or switch connections in an Ethernet network must form a tree and not a ring; otherwise duplication of packets and network overload may result. In this situation, the Ethernet modules will continually reset. Proper IP Addressing is Always Essential The CPU’s embedded Ethernet Interface must be configured with the correct IP Address for proper operation in a TCP/IP Ethernet network. Use of incorrect IP addresses can disrupt network operation for the PLC and other nodes on the network. Refer to TCP/IP Ethernet for Series 90-30 CPU374 PLUS User's Manual, GFK-2382 for important information on IP addressing. When storing a new HW configuration to the PLC, be sure that the HW configuration contains the proper Ethernet addressing data (IP Address, Subnet Mask, and Gateway IP Address) for the PLC. Note: Machine Edition programming software maintains the target IP address (used to connect the programmer to the target) independent of the contents of the HW Configuration for that target. The target IP address is set in the Target Properties in the ME Inspector window. Storing a HW Configuration whose Ethernet addressing data contains an IP Address that is different from the PLC target IP address will change the IP address used by the target PLC as soon as the Store operation is completed; this will break the Programmer connection. Before attempting to reconnect the Programmer, you must change the target IP address in the Target Properties in the CME Inspector window to use the new IP address. To regain communication at the former IP address, use the manual corrective action described above. Storing a HW Configuration containing default (0.0.0.0) or incorrect Ethernet addressing data to the PLC will result in loss of the Programmer connection and will require manual corrective action as described above. Reporting of Duplicate IP Address The CPU374 does not log an exception or a fault in the PLC Fault Table when it detects a duplicate IP address on the network. Multiple Zero-Period EGD Exchanges May Not Produce Similar Numbers of Samples If more than one EGD produced exchange is configured for a production period of zero, the exchanges may not produce similar numbers of samples. Due to the way that scheduling occurs when multiple exchanges are scheduled as fast as possible, some zero period exchanges may produce significantly more samples than others. For more consistent EGD production, configure the produced EGD exchanges with non-zero production periods. Changing IP Address While SRTP Connection Open May Generate Log Events Open SRTP Server connections established with a remote SRTP client are not terminated as expected when the PLC’s IP address is changed (typically by storing a new HW Configuration). A Series 90 SRTP client (SRTP channels) reports either a 9690H or 0190H status; the SRTP connection may remain open until the connection is terminated as a result of a client timeout. 10 Series 90-30 CPU GFK-2123Y Subject Description AUP Parameter Should Not be Changed The Advanced User Parameter wsnd_buf should not be changed by the user. Changing the value of this parameter may cause the LAN led to go out and the Ethernet Interface to drop connection. Heavy Load Can Block Station Manager As explained in the TCP/IP Ethernet Station Manager Manual, GFK-2383, Chapter 1, a heavy EGD and/or SRTP load can block Station Manager operation. Web Server Browser Restrictions Internet Explorer version 4.0 running on Windows 98 will give an error when the reference table web page is accessed. Web Server operation has been verified with Internet Explorer version 5.0 Very Heavy EGD Production/Consumption at Server May Cause EGD Command Timeouts Very heavy EGD production and/or consumption at a server device may cause EGD command timeout errors when another device attempts to send EGD commands to that server. If EGD commands must preempt normal production, you may set the gcmd_pri Advanced User Parameter to 2 (see GFK-2382, Appendix A). Note that by doing so, EGD exchange production may be delayed. SRTP Application Timeouts Must Accommodate Network Connection Overhead The application timeouts within SRTP Channels also include the time needed to establish and maintain the underlying network and SRTP connection. Examples are establishing the TCP connection for a new channel, establishing communication with the remote device, and TCP retransmissions during Channel operations. If the time needed for TCP connection establishment or maintenance exceeds the user-specified channel application timeout values, an application timeout will occur. Channel application timeouts are temporary errors; the channel continues to run. AUP Parameter gcmd_pri Does Not Affect the Behavior of EGD The Advanced User Parameter gcmd_pri does not have the desired effect in the CPU374. Under sufficiently heavy EGD data exchange load, EGD commands may still be blocked from execution. Firmware Update Failure with Reset of Daughter Board Fault Some revision -EK and -EL units may exhibit random reset of daughter board faults in the PLC Fault Table. These units may fail during a firmware update. Customers who experience this issue should contact Technical Support. SRTP channel data coherency for atomic operations is limited to 256 bytes (128 words). For SRTP channel transfers, data lengths beyond 256 bytes are not guaranteed to have coherency as they are not guaranteed to be all written at once. The channel status bits or RDCS status should be used to determine when the entire transfer is completed. Requests for invalid memory types on remote servers can return different error codes. The error code generated when accessing an invalid memory type on a remote server for a CPU374 PLUS is not the error code expected. The expected error code is 8390, however a 9590 error code is received. Ethernet Programmer May Briefly Lose Communications When Configuration Stored Storing a PLC configuration containing Ethernet configuration values may require the Ethernet interface to restart itself in order to use any changed configuration values. When the Ethernet interface restarts, an Ethernet PLC Programmer briefly reports a loss of communications. If this occurs, the Ethernet Interface will post two or more PLC faults with the text LAN systemsoftware fault; resuming, and fault-specific data starting with 080008 and/or 080042. In addition, faults with text Bad remote application request; discarded request (1B0021) and Local request to send rejected; discarded request (110005) may occur. When these faults occur, the STAT LED on the CPU374 is turned off to indicate posting of faults to the PLC fault tables. In some cases, a 10-second delay may occur before loss of communications is detected. Normal operation resumes once the Ethernet Interface restarts. The STAT LED can be reset using the Station Manager OK command. When the PLC configuration is stored from an Ethernet PLC Programmer, the communications loss occurs immediately after successful completion of the store. Attempts to store configuration plus logic and/or reference tables in one operation can fail. However, storing configuration separately from logic or reference tables always succeeds. Series 90-30 CPU 11 GFK-2123Y Subject Description Store of Program or Reference Tables to Flash May Cause Loss of Ethernet Communications While storing the PLC program, configuration, and/or reference tables from PLC RAM memory into Flash memory or to the EZ Program Store device, Ethernet data communications may be lost. Normal data transfers are temporarily suspended during a Flash or EZ Program Store device store operation. In these cases, Ethernet data transfers (such as used by an Ethernet PLC Programmer connection) will fail when the store exceeds the 16-second maximum period allowed for completion. Upon completion of the store operation, normal operation will resume. If a timeout occurs during a store to Flash or EZ Program Store device, the timeout value should be increased in the programming software being used. See the User’s Manual for the programming software for more details. COMMREQ status word returns AA90 (attempt to establish a TCP connection with a remote server failed) error code For connections with Ethernet channels (Modbus/TCP or SRTP), if the connect COMMREQ or subsequent RDCS command returns an AA90 error code in the COMMREQ status word, the connection attempt should be tried again within user logic. COMMREQ status word returns 8890 (invalid channel number) error code If the connect COMMREQ for a Modbus/TCP client connection returns a successful status (1) but subsequent COMMREQs on the connection result in an 8890 status, the connection should be tried again within user logic. Subsequent COMMREQs on the newly re-opened connection should succeed. Station Manager RMDIR (remove directory) Commands Issuing the Station Manager command RMDIR dir1/dir2 does not result in dir2 being removed. Instead, the error RMDIR failed, dir1/dir2 does not exist is returned. As a workaround, use CD dir1 to reach the subdirectory before issuing RMDIR dir2. Client Channels TCP Resource Management There is a period of time that the OS Network stack hangs on to the TCP resources associated with a connection after it is closed. It applies to the initiator of the close, which is almost always the client side. This time is referred to as the TCP Linger Period. Once the TCP Linger Period expires (60 seconds in the current OS implementation), the TCP resources are released. Application developers using client channels need to be aware of this behavior when designing their logic. There are a finite number of TCP resources allocated to client channels, and if channel connections are brought up and down so fast that these resources are depleted, then the application may have to wait until a TCP resource frees up in order to establish another client channel (a COMMREQ Status of 0xA890 is returned if no TCP resources are currently available; application should wait and retry again). SRTP Client Channels provides features that help the user preserve TCP connections. These include a period time where one can establish an SRTP Channel and specify the channel to run at a given interval, or run as fast a possible. One can also specify a number of iterations, or run forever. Additionally, SRTP Channels allows re-tasking of an active channel to the same remote device, where the parameters of an active channel, such as the channel command type (Read/Write), number of repetitions, time periods, local memory address, remote memory address, etc. can be changed. SRTP Channels also allows re-tasking of an active channel to a different remote device (changing the remote device’s IP address, etc.). However, re-tasking to a different remote device will neither conserve TCP connections, nor save on the time it takes to create a channel. 12 Series 90-30 CPU GFK-2123Y Product Documentation Series 90-30 PLC Installation and Hardware Manual, GFK-0356 Series 90-30/20/Micro PLC CPU Instruction Set Reference Manual, GFK-0467 TCP/IP Ethernet for Series 90-30 CPU374 User's Manual, GFK-2382 TCP/IP Ethernet for Series 90-30 CPU374 Station Manager Manual, GFK-2383 Installation in Hazardous Areas The following information is for products bearing the UL marking for Hazardous Areas: • WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2. • WARNING - EXPLOSION HAZARD - WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING OR WIRING MODULES. • WARNING - EXPLOSION HAZARD - DO NOT CONNECT OR DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS. • EQUIPMENT LABELED WITH REFERENCE TO CLASS I, GROUPS A, B, C & D, DIV. 2 HAZARDOUS LOCATIONS IS SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C, D OR NON-HAZARDOUS LOCATIONS ONLY.
