If ESS is enabled and the UPS will be fed by a site generator at any time, the On Generator building alarm must
be wired and configured to a Building Alarm Input. Wiring the On Generator sensing circuit to a building alarm
allows the UPS to optimize its operation with the generator by transferring the UPS from ESS mode to Normal
(double conversion) mode.
NOTE 1
A UPS building alarm input is used to indicate On Generator.
NOTE 2
Any pair of unused building alarm terminals may be used for On Generator connections.
NOTE 3
Program the building alarm to read On Generator and for either Normally Open (default)

If installing interface wiring connections between standalone cabinets, conduit must be
installed between cabinets.
