1.3 Overview

The UPS provides two power paths between the utility source and the critical load. Figure 1.1

shows the path for normal operation, with the load powered from the inverter. Figure 1.2 shows

the path for bypass operation, with the load supplied through the static bypass line.

FIGURE 1.1

Single Line Diagram - Normal Operation. Load powered by inverter.

During normal operation, the path through the inverter is used to power the load.

Referring to Figure 1.1: Input AC power is converted to DC by the Converter. DC power is utilized to

charge the UPS battery and to provide power to the Inverter. The Inverter converts the DC 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 Input circuit breaker(MCCB) for protection of the UPS and cables are field supplied and field

installed. (See WARNING 2 in section 1.0).
