Signal Input Monitoring; General Purpose Relay Contact - Eaton 93PR User And Installation Manual

5.3. Signal input Monitoring

This standard feature lets you connect the UPS to your signal inputs, such as smoke detectors or over temperature
alarms. The customer interface terminals for external connections are located inside the UPS. You should use
twisted-pair wires for each alarm input and common.
The signal inputs can be programmed to display the alarm functional name.

5.4. General Purpose Relay Contact

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. 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. This feature is useful if the UPS is located in a remote area where
the UPS horn may not be heard immediately.
Contacts should not be operated in excess of 30 Vac (RMS) and 30 Vdc at 5 A maximum.
