4.7 Emergency Power Off (EPO) Interface
The UPS may be switched off by a remotely operated Emergency Power Off control. Such a configuration is common in
computer rooms and laboratories where, for safety reasons, power to the loads must be disconnected. The EPO interface
is a 6 position modular jack with an offset latch. Connection to a remotely located EPO switch may be accomplished as
shown below.
Caution: The EPO interface is a Safety Extra Low Voltage (SELV) circuit and may be connected only to other SELV
circuits.
Caution: The EPO interface is designed to monitor circuits that have no determined voltage potential.
Such closure circuits may be provided by a switch or relay properly isolated from the utility.
Connection of the EPO interface to any circuit other than a closure type circuit may cause damage to
the Electronics Unit.
