OFF: The BS signal is always valid (receivable).

The unit’s “power output ” can be stopped by inputting a “ON” backup power supply stop signal (BS) that continues for 10 seconds or more.

ON: The BS signal is valid (receivable) only when in Battery Mode. (The signal is not received when in Commercial Power Mode.)

The unit’s “power output ” can be stopped by inputting a “ON” backup power supply stop signal (BS) that continues for 0.01 (10 ms) seconds or more.

Use this setting in commercial operation when you do not want to stop operations when a backup power supply stop signal (BS) is received.

•Auto startup operation when power is restored

Auto startup when power is restored is associated with setting switch 2.

However, the unit does not start up when the BS signal is ON.
