Issue:
How do I connect the RPO (Remote Power Off) function if using multiple CL‑NA units?

Product Line:
Context CL‑NA (multiple CL-unit installations)
This product was discontinued, and equivalent equipment may be selected based on site requirements.

Environment:
Installations using multiple CL units with RPO (Remote Power Off) functionality

Cause:
By default, the unit comes with a shorting link connection if the RPO function is not being used.

Resolution:
If planning to use multiple CL units with RPO functionality, you need to:
-Remove the shorting link from the RPO terminals.
-Daisy-chain the RPO terminals across the CL units as shown in Figure 1.
-Ensure the last device in the daisy chain is connected to an external switch with Normally Closed (NC) contacts (see Figure 1).

Note: The last device in the daisy chain will be connected to an external switch which has normally closed contacts.
