Relay Output Interface Connections

The general alarm relay is a dry relay signal output. The relay can be used for informing the
operators about UPS alarm conditions, for example through a building management system.
By default, the relay is configured to activate when the UPS general alarm is active, that is, any
event having ALARM status is active. The relay can also be configured to activate by some
other event but this needs to be done by authorized service.
Relay signal wiring can be installed only through the signal cabling canal, from back to front, on
the top section of the UPS.
