To properly install the adapter for remote mounting of the Series NRX CAM module, follow these steps:
1. Ensure you have the necessary kit contents: Adapter Harness – CAM module to NRX Breaker Secondary, Ferrule 2-18AWG (Weidmuller PN 9004310000), and Installation Instructions.
2. Note that the kit does not include the DIN rail for mounting the CAM module.
3. Connect the adapter cable to the NRX circuit breaker. The adapter consists of a 1 meter (3 ft.) length of cable that connects between the CAM module and the breaker secondary.
4. Mount the CAM module on a length of standard grounded DIN rail. The CAM module connector is keyed to fit in only one direction.
5. The numbered flags on each wire of the cable directly correspond with the breaker secondary terminal designators. When connecting the adapter to the CAM module, ensure Pin 19 (as indicated by the numbered flags) is positioned in the lower left.
6. The drain wire may be connected to the SHIELD terminal on the MCAM or ICAM, or it may be connected to the grounded DIN rail. If a PCAM or ECAM module is used, use the provided 2-18 AWG Ferrule to connect the cable drain wire for a proper connection to the power supply ground terminal.
