Descriptions
Input of the UPS Stop Signal
(BS)
When the BS signal is ON (High), the output of the
UPS is stopped after the time period specified in
advance has elapsed. (Note 1).
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.
In the factory settings, the UPS stops operation
when this is short-circuited.
In addition, it is necessary to turn on the “Power”
switch of UPS to use this function (Note 2).
Note1: BS Delay Time:
You can set the amount of time between when the BS signal is received and when
the output of the UPS is stopped (See also "3-5-2 Settings" ( P.55 ) ).
You can stop the output of the UPS by inputting the voltage signal (HIGH) that lasts
at least 10 seconds from the outside.
Note2: Connection terminals are at contact signal port pins 6, 7 and the remote ON/OFF
port (See also "3-1-4 Setting Switch" ( P.35 ) ).
