power to clean AC power to supply the critical load.
The conversion - inversion process eliminates any voltage transients or fluctuations existing in the
input power before it reaches the critical load.
The power drawn by the critical load is equally shared between all UPS whenever the system is in
the Parallel Operation. (Refer to Figure 3.4 that shows a sample of Parallel Operation System
Configuration.)
In the event of a UPS module failure during Parallel Operation, the critical load power will be
continually supplied and shared by all other UPS.
The Bypass Input circuit breaker (MCCB) for protection of the UPS and cables are field
supplied and field installed. (See WARNING 4 on page 1-4).
