PSM Module to Terminal Assembly Connections
Two identical 2-meter cables (Emerson part number IC694CBL200) connect the PSM
module to the Terminal Assembly. These cables are to be used only for Grid 1 and Grid 2
connections to the IC694PSM001.
WARNING
The PSM Terminal Assembly connects to hazardous voltages. Before installing, testing, or
troubleshooting this module, you should refer to the complete instructions in this manual.
Failure to follow the published guidelines may result in personal injury, equipment damage,
or both.
The interface cables connect to a circuit board that has hazardous voltages present. These
cables are carefully made to ensure the safety of the user and associated equipment.
Therefore, we recommend you use only factory-built cables.
Secure the cables between the Terminal Assembly and the PSM module to maintain at least
1/4-inch (6mm) distance to other wiring unless it is Class 2 or Communication wiring. The
cables are for interconnection within the same enclosure only.
If hot swapping the IC694PSM001 module becomes necessary, the IC694CBL200 cables
should be disconnected from the IC694ACC200 terminal assembly end first, to remove any
potential from the cables.
Note whether the cables were plugged into the 120V or 600V connectors on the terminal
assembly, so they can be returned to the proper connector.
