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 1.3 shows the path for battery operation, with the load supplied from the inverter.

A) Normal Operation.

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 AC Bypass Input circuit breaker (MCCB) for protection of the UPS and cables are field

supplied and field installed. (See WARNING 2 on page 1-2)
