NOTE: A separate contact must simultaneously cause UPS input AC power to be removed.

5Connect the switch or circuit to the REPO connector on the UPS rear panel using insulated 0.75 mm2–0.5 mm2 (18–20 AWG) wire.

Optional. If you are daisy-chaining the REPO function with another UPS, connect the REPO port labeled “OUT” to the REPO port labeled “IN” on the next UPS. Continue for each UPS. On the last UPS in the daisy-chain, connect a REPO connector (without a jumper) in the REPO port labeled “OUT.”

6Verify that the externally-connected REPO switch is not activated to enable power to the UPS output receptacles.

7Continue to the following section, “UPS Initial Startup.”

UPS Initial Startup

To start up the UPS:

1Verify that the internal batteries are connected.

2If an optional EBM is installed, verify that the EBM is connected to the UPS.

3Verify that the power input to the UPS has adequate upstream overcurrent protection:
