3.2.4 EPO Connection
Emergency Power Off (EPO) function is a
standard feature for the UPS. The EPO polarity is
configurable, and it is normally closed as a
default setting. If the connection between the
two ports of the EPO connector is disconnected,
EPO function will be active, and the UPS will stop
output power immediately.
3.2.4.1 Normally open
Normally the EPO connector is open on the rear
panel. Once the connector is closed with a wire, the
UPS will stop output until the EPO status is reset.
3.2.4.2 Normally closed
Normally the EPO connector is closed with a wire on
the rear panel. Once the connector is open, the UPS
will stop output until the EPO status is disabled.
