● Remote ON/OFF Signal
Remote ON/OFF signals can be used to start and stop
the UPS, by using either an externally connected con-
tact 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 pos-
sible to start up UPS by the remote ON/OFF signals even
though cold start is set ON.)
Connection terminals are at contact signal connector pins
6 ,7 and the remote ON/OFF connector.
