2 System Overview

PROTECT A. is an uninterruptible power supply

(UPS) for essential loads such as

PCs, workstations,

relatively small-

scale telecommunication equipment

and similar devices.

The PROTECT A. series is a compact, interactively operating

UPS available with nominal power output ratings 500, 700,

1000 and 1400 VA.

This document describes both types, PROTECT A. 1000 and

PROTECT A.1400.

2.1 Brief Overview

The LED display and a pushbutton switch are located on the

front of the UPS for straightforward monitoring and operation.

The display unit clearly shows the various operating modes

using simple pictograms and displays the voltage values and

utilisation level of the UPS in numerical format. In addition, the

remaining standby time in battery operation is shown in

numerical format.

The connections for the mains and the loads are located on

the rear of the PROTECT A., as are the communication

interfaces and connections for telephone lines/network cables.
