Installation & Operations Manual Uninterruptible Power Supply Monitor (2500-UPSMONITOR)
The RATH® 2500-UPSMONITOR can be used on either the RATH® RP7700104 or
RP7701500 to provide a physical indication (via relay contact either closing
or opening) of primary power loss.
Connecting 2500-UPSMONITOR:
1. Connect the Positive (+) lead of the supplied 24vdc transformer to the
power input terminal marked 24 and the negative (-) lead to the power input
terminal marked 0.
2. Connect signal wiring (not supplied) to the desired Normally Closed (NC)
or Normally Open (NO) contact and Common (COM) connections on one set of the
relay output terminals.
3. Plug the 24vdc transformer into power outlet on UPS. Outlets marked
Battery Backup monitor UPS power. Outlet marked Surge Only monitors loss of
primary power to UPS. Note: When using the RP7701500, the transformer must be
plugged into a parallel AC power outlet to monitor the AC input to the unit.
4. Test unit by unplugging the primary power cable on UPS to check relay for
change of state. To test loss on RP7701500, either kill power on the 110vac
outlet, or unplug the 24v transformer.
