● 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 func-
tion, 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 connector pins 6 ,7
and the remote ON/OFF connector.
3. Items that can be set using the contact signal card
Please make a cable to connect to the system by yourself.
