 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.

 Always test the REPO function before applying your critical load to avoid accidental load loss.

Remove Jumper if

installed

To install the REPO switch:

1

Verify that the UPS is off and unplugged.

2

Remove the REPO connector from the accessory kit.

 Verify that there is no jumper installed in the REPO connector. If a jumper is installed, remove it before

connecting to the REPO port.

3

Connect the REPO connector to the REPO port labeled “IN” on the UPS rear panel.

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.”
