EPO is connected to the UPS's top front panel, on connector EPO. The connections of the
EPO switch are shown in illustration 9.
For information on installing interface connections, refer to the Eaton 91PS/93PS 8-10 kW
UPS User's and Installation Guide.
One general purpose relay contact is provided as a standard feature on the UPS. An alarm
contact is also provided.
You can use a normally-closed or normally-open contact. See illustration 10. If the state of
the contact changes from the state you specify as normal, a signal is issued. You can
connect this contact to equipment at your facility (such as a light or an alarm bell) to let you
know when an alarm is active on the UPS.
NOTE: Contacts should not be operated in excess of 30 VAC (RMS) and 30 VDC at 5 A
maximum.
