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. To use this function, turn
on the Power Switch of the UPS. (Note: 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.)
Connection terminals are at contact signal con-
nector pins 6 ,7 and the remote ON/OFF con-
nector.
