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.
