UPS installation 23
1. Verify that the UPS is powered down and all power sources are removed. For more information, see
"Powering down the standalone UPS (on page 72)."
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.
Connecting the UPS to utility power
WARNING: To prevent injury from electric shock or damage to the equipment:
• Plug the input line cord into a grounded (earthed) electrical outlet that is installed near the
equipment and is easily accessible.
• Do not disable the grounding plug on the input line cord. The grounding plug is an important
safety feature.
• Do not use extension cords.
Connect the UPS to a grounded utility power outlet.
