4. Operation
●
UPS stop signal setting (setting switch 7 ) … Factory-shipped setting: OFF
(Only for BX50FW, BX75SW)
OFF: The unit’s power output can be stopped by inputting a “High” backup power supply stop signal (BS)
that continues for 10 seconds or more. The power supply output is stopped with a voltage signal
input, even in commercial operation.
After stopping power output, a “Low” backup power supply stop signal (BS) restarts the unit once
the commercial power supply is normal. However, it does not restart if the automatic restart setting
(setting switch 2 ) is ON.
ON:
The unit’s power output can be stopped by inputting a “High” backup power supply stop signal (BS)
that continues for 0.01 (10 ms) seconds or more. Power supply output can be stopped when the
stop signal is received, only during backup operation (Battery Mode).
After stopping power output, a “Low” backup power supply stop signal (BS) restarts the unit once
the error that caused the power failure is eliminated.
Use this setting in commercial operation when you do not want to stop operations when a backup
power supply stop signal (BS) is received.

Caution
• Before operating the switching switch, turn OFF the power switch of the main unit and unplug the AC
input plug (turn OFF the AC input).
• If the switching switch is changed during operation, communication with peripherals (PC, etc.) will
cease to perform normally.
• If the AC input plug is not disconnected, the switching switch setting changes will not become valid.
Use when switching the communication interface (serial communication, contact com-
munication).
