Shutdown delay timing
This delay corresponds to the settings
for switch 5 and switch 6 .
This timing is 10 ms or 10 sec.
Timing corresponds to the settings
for switch 7 .
The UPS delays the shutdown timing.
If the user sets “switch 5: ON, switch 6: ON”, the UPS does not stop the output, even if the backup power
supply stop signal (BS) is valid.
<Note>
The remote ON/OFF signal is not related to this setting.
When the remote ON/OFF signal is “High”, the UPS stops the output immediately.
