WARNING! Risk of electrical shock. Can cause equipment damage, injury and death.
The EPO action of the UPS will shutdown the rectifier, inverter, and static bypass, but it does not disconnect
input power to the UPS. To electrically isolate the UPS, an interface with the external REPO circuit must be
field supplied to allow disconnecting the UPS input feeder breaker to remove all sources of power to the UPS
and connected equipment to comply with national and local wiring codes and regulations.
The Figure 2.2 on page7, shows the location of the REPO connection inside the UPS front panel. Figure 3.5 on the next page,
shows the connection details.
If a REPOconnection is not required for the UPS, the factory installed jumper between Pin2 and Pin4 must remain installed
for the UPS to operate.
NOTE: The terminal block wire range is 18AWG to 22AWG (0.82mm
2
to 0.33mm
2
), and we recommend using 18 AWG
copper, shielded, and signal cable.If the REPO will trip an external, electronically controlled circuit breaker, you must
reset the breaker before starting the UPS after the REPO is activated.
NOTE: We recommend that you route the wiring for the REPO connection from the rear of the UPS through the built in
wiring pass through to connect to the REPO port. See Figure 2.2 on page7, for the location of the pass through.
