Remote ON/OFF Signal
Remote ON/OFF signals can be used to start and stop the
UPS, by using either an externally connected contact or the
ON/OFF status of the open collector circuit.
When signal is OFF, the UPS will be turned on. When signal is
ON, the UPS will be turned off.
This is OFF when short-circuit at the factory settings (Note 1).
In addition, it is necessary to turn on the power supply switch
of UPS to use this function (Note 2).
Note 1: If you want the UPS to stop operation when this is open, or if you want to disable this
function, specify OFF or disable in “Setting” - “Dry Contact” - “Remote ON/OFF Logic”.
Note 2: When there is no AC power supply, it is not possible to start up UPS by the remote
ON/OFF signals even though cold start is set ON.
