UPS MODES OF OPERATION
A.
Normal: The input converter and output inverter shall operate in an on-line manner to
continuously regulate power to the critical load. The input and output converters shall
be capable of full battery recharge while simultaneously providing regulated power to
the load for all line and load conditions within the range of the UPS specifications.

be capable of full battery recharge while simultaneously providing regulated power to
the load for all line and load conditions within the range of the UPS specifications.
B.
Battery: Upon failure of the AC input source, the critical load shall continue being
supplied by the output inverter, which shall derive its power from the battery system.
There shall be no interruption in power to the critical load during both transfers to
battery operation and retransfers from battery to normal operation.

Recharge: Upon restoration of the AC input source, the input converter and output
inverter shall simultaneously recharge the battery and provide regulated power to the
critical load.
inverter shall simultaneously recharge the battery and provide regulated power to the
critical load.
D.
Static Bypass: The static bypass shall be used to provide transfer of critical load from
the Inverter output to the bypass source. This transfer, along with its retransfer, shall
take place with no power interruption to the critical load. In the event of an emergency,
this transfer shall be an automatic function.

this transfer shall be an automatic function.
E.
Maintenance Bypass: The system shall be equipped with an external make-before-break
Maintenance Bypass Cabinet (MBC) to electrically isolate the UPS during routine
maintenance and service of the UPS. The MBC shall completely isolate both the UPS
input and output connections.
