NOTE: When removing an EBC, the circuit breaker on the rear of the cabinet must be turned off before
disconnecting the cable.
NOTE: If the UPS will be shipped or stored for an extended time, the connector should be
disconnected. This will minimize any stand-by current drain on the batteries and help attain their
design life.
