How do I correctly connect the NOTIFIER MPS-TR Remote Trouble Relay?

[Mckenzie]

To connect the NOTIFIER MPS-TR Power Supply Remote Trouble Relay, follow these steps to ensure proper functionality:

1. Mounting the MPS-TR: Begin by removing the upper and lower screws from the right side of the power supply main board. The MPS-TR is designed to mount using these two holes. Use the longer screws and standoff sleeves provided with the MPS-TR. Place the screws through the MPS-TR board and the standoff sleeves, then thread them into the holes where the original screws were.

2. Installing the Standoff: Insert the nylon standoff into the appropriate hole in the middle of the MPS-TR board. The correct hole is labeled on the MPS-TR board and depends on your specific power supply model. After selecting the correct hole, secure the standoff. The threaded end of the nylon standoff doesn't thread into anything; it acts as a separator to prevent contact between the MPS-TR board and other system components.

3. Connecting P1 to P3: Use the provided power ribbon cable (part number 71085), which comes with the MPS-TR board, to connect P1 on the MPS-TR to P3 on the power supply.

4. Connecting the Relay Contacts: Connect the common (C) and normally closed (NC) contacts of the Form C relay on the MPS-TR to the normally closed TROUBLE INPUT on your ACM-16AT, ACM-32A, or MMX-1 module. This setup allows the trouble relay to signal issues to your monitoring system. By carefully following these instructions, you'll be able to effectively supervise your remote power supplies using the MPS-TR.
