3.
Connect the appropriate external switch to the selected REPO contact. See
Figure 51 for NO REPO wiring and Figure 52 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
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
Always test the REPO function before applying your critical load to avoid accidental load loss.

Installing REPO for a Parallel System
You can install an optional REPO circuit that shuts down the entire parallel system
using a single switch. To install a REPO switch for a parallel system, the selected
REPO command (NO or NC) contacts from each UPS in the system must be in
parallel.
To install a REPO switch for a parallel system:
1.
Verify that the UPS system is turned off and all power sources are removed. See
“Parallel System Shutdown” on page 73 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 Pin 1 to Pin 1 and connect Pin 2 to Pin 2 of each UPS in parallel for the
selected REPO contacts, then connect the appropriate external switch to the
selected REPO contact. See Figure 53 for NO REPO wiring and Figure 54 for NC
REPO wiring.
4.
Reconnect the REPO connector pins and turn on the UPS manually to restart.
Short the pins to keep the UPS running. Maximum resistance is 10 ohm.
