2.4.2 Multi-Module Communication
Paralleling cables that connect the module to the system are connected to terminals P3101 and P3103
on the Inter-Module Communication (IMC) board (refer to
4.0 - Installation Drawings
).

1. Belden 810x or Belden 89901 cables are the only approved cables.
2. Belden 89901 cable can be used for underground installations.
3. If using multiple parallel cables for each run, all cables must be run in the same conduit.
4. Each cable group should be run in a separate grounded conduit to ensure redundancy.
5. The maximum lengths must include all the parallel cables from the first module to the last module. The primary and redundant
cable lengths can be counted separately.
6. The ground pins on the Inter-Module Communication Board (Pins 7 and 14) are connected together on the board. If using
cable with only one (1) drain wire, then connect to the ground to Pin 7.
7. Care must be taken so drain wire does not touch any other component in module.
8. Attach control wires to side of control door where Inter-Module Board (IMC) is attached. Do not run wires across IMC board.
