Each Eaton 9155 UPS ships with power management software and an interface cable. To begin installing
power management software, see the instructions accompanying the Software Suite CD.
NOTE
Power management software provides up-to-date graphics of UPS power and system data and power flow. It
also gives you a complete record of critical power events, and it notifies you of important UPS or power
information. If there is a power outage and the Eaton 9155 UPS battery power becomes low, power
management software can automatically shut down your computer system to protect your data before the UPS
shutdown occurs.

The cables should be connected to the control terminals with a mating connector. Input and output terminals
have a functional isolation from terminal to terminal. They are connected to the UPS chassis through individual
1 MΩ resistors.

REPO is used to shut down the UPS from a distance. This feature can be used for shutting down the load and
the UPS by thermal relay, for instance in the event of room overtemperature. When REPO is activated, the UPS
shuts down all converters, de-energizes all system relays, trips the battery circuit breaker, and fully powers
down within 10-15 seconds.
