Installing REPO for a Standalone UPS

To install a REPO switch for a standalone UPS:
1. Verify that the UPS is turned off and all power sources are removed. See "Standalone UPS Shutdown" on
page 102 for shutdown instructions.
2. Securely mount the remote REPO switch. Recommended locations include near operator's consoles or
near exit doors. Refer to the REPO switch manufacturer's installation instructions for enclosure
dimensions and wiring knockouts.
3. Connect the appropriate external switch to the selected REPO contact. See Figure 76 for NO REPO wiring
and Figure 77 for NC REPO wiring.
4. Reconnect the REPO connector pins and turn on the UPS manually to restart. The pins must be shorted to
keep the UPS running. Maximum resistance is 10 ohm.
NOTE 1 The REPO wiring of a standalone UPS can be connected with the REPO wiring of a
parallel system if the same sense (NO or NC) contacts are used. Be sure to match
the polarity for the contacts.
NOTE 2 Always test the REPO function before applying your critical load to avoid accidental
load loss.
