UPS Operation: Manual Maintenance Bypass Mode
When it becomes necessary to perform maintenance checks on the UPS, the critical load need
not be interrupted. This is accomplished by means of a “make-before-break” manual
maintenance bypass switch. This same switch simultaneously isolates the output of the UPS,
which will allow the rectifier and inverter to be energized for troubleshooting and repair
purposes, without affecting the critical load.
