PSM Module to Terminal Assembly Connections
GFK-2749
Two identical 2-meter cables (GEIP 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.
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.
Note: The following information is supplied only for diagnostics (making continuity
checks of the cable):
These cables have straight through connections (pin 1 connects to pin 1; pin 2
connects to pin 2, etc.). The cables are twisted-pair type, connected to minimize
noise and crosstalk between signals.
