Verify that the UPS is powered down and all power sources are removed. For more information, see
"Powering down the standalone UPS (on page

2.

Mount the remote REPO switch. HP recommends mounting the REPO switch near the operator's
consoles or near the exit doors. For enclosure dimensions and wiring knockouts, see the REPO switch

manufacturer's installation instructions.

3.

Connect the appropriate external switch to terminal block 5, normally-closed REPO, and then discard
the jumper wire.

IMPORTANT:

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

load loss. For more information, see "Verifying the REPO port connection (on page

71

4.

Reconnect terminal block 5, normally-closed REPO, and then power on the UPS manually to restart. The
pins must be shorted to keep the UPS running. Maximum resistance is 10 ohm.
