Maintenance Bypass Mode:
In case of UPS maintenance or battery replacement, and where the load cannot be
interrupted, the user can turn off the inverter, close the bypass breaker and then open
the rectifier and reserve breakers. The AC output will not be interrupted during
manual bypass transfer procedure. Therefore, the maintenance bypass switch keeps
continuously supplying power to the load. Electricity will not exist in UPS except the
output transformer, thus ensuring the safety of service personnel.
Generally, the UPS is expected to run 24 Hours a day in normal operation mode once
it is installed, except when the utility power fails, under overload conditions, or
during maintenance.
Normal operation with batteries connected provides clean, stable, regulated and
uninterrupted power to the load, free from any spikes and surges. Therefore, the UPS
can be regarded as a perfect AC power source, limited in back-up time, under mains
failure, only by the capacity of the batteries.
