One general purpose relay contact is provided as a standard feature on the UPS. An alarm
contact is also provided. The output relay configurations are shown in illustration 13.
You can use a normally-closed or normally-open contact. 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.
