Installation
NOTE: The pins must be open to keep the UPS running. If the UPS shuts down because the REPO connector
pins are shorted, restart the UPS by re-opening the REPO connector pins and turning on the UPS manually.
Maximum resistance in the shorted loop is 10 ohm.
NOTE: Always test the REPO function before applying your critical load to avoid accidental load loss.

connecting to the REPO port.
3 Connect the REPO connector to the REPO port labeled “IN” on the UPS rear panel.
4 Optional. If you are daisy-chaining the REPO function with another UPS, you can shut down the
entire system using a single switch.
Connect the second REPO connector to the REPO port labeled “OUT.”
NOTE:
A separate contact must simultaneously cause UPS input AC power to be removed.

labeled “OUT” to the REPO port labeled “IN” on the next UPS. Continue for each UPS. On the
last UPS in the daisy-chain, connect a REPO connector (without a jumper) in the REPO port
labeled “OUT.”
6 Verify that the externally-connected REPO switch is not activated to enable power to the UPS
output receptacles.
