NOTE: Pins 7 and 8 are shorted before delivery.
NOTE: The emergency power off (EPO) action of the UPS closes the rectifier, inverter and static bypass, but it cannot
disconnect the UPS mains input inside. To completely disconnect the UPS, disconnect the upstream input circuit
breaker when generating the EPO. For details on REPO connection and operation, see Connecting a Remote
Emergency Power Off (REPO) Switch on page28.
