Signal
Description
Disable Bypass Operation If active, the automatic transfer to the static bypass is prevented.
Charger Off If active, the battery charge function is disabled. In a utility power outage, the
discharge of batteries is supported.
Remote ON/OFF
If active, the UPS output turns off regardless of the mode of operation. Auxiliary
power, fan, communication, and rectifier/battery charger remain functional. Restart is
initiated immediately when this signal is inactive.
Request Bypass If active, the UPS transfers to bypass if the bypass voltage, frequency, and
synchronization are all okay.
Request Normal If active, the UPS transfers to inverter operation if not prohibited by REPO or an alarm
condition.
Force Bypass If active, the UPS is forced to static bypass operation regardless of the bypass status.
External Battery Breaker Status If active, the UPS knows that the batteries are disconnected.
Building Alarm 1-6 These alarms can be activated separately or at the same time with other building
alarms.
Not in Use Default
Shutdown If active, the UPS shuts down immediately.
Delayed Shutdown
If active, the UPS shuts down after a user-configured delay time. Default shutdown
delay is 120 seconds. The UPS automatically restarts when the signal changes to
inactive.
Normal/Bypass If active, the UPS transfers to bypass if okay. If inactive, the UPS transfers to the
inverter when possible.
On Generator If active, the UPS knows that input is fed from the generator. Bypass is disabled; the
automatic battery test is disabled.
External Transformer Overtemperature This option is not used.
