14. Maintenance Bypass Power Supply (Option)
You can combine this UPS with an optional Maintenance Bypass Unit. In the event of a failure in the UPS, you can then exchange the UPS after manually switching from bypass power supply to maintenance bypass power supply.
Note
The following description applies to use with an optional Maintenance Bypass Unit.
Normally, do not change the setting of the Forced Bypass switch. Leave it set to the “Inverter” side.
If you do set the Forced Bypass switch to the “Bypass” side, to perform maintenance or for some other reason, remember to set it back to the “Inverter” side when resuming normal operation. After
setting it back to the “Inverter” side, press 
on the control panel and hold it for at least 1 second.
The switch is located inside the battery cover.
