2 System Overview

PROTECTA. is an uninterruptible power supply
(UPS) for essential loads such as PCs, work-

i

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. 500 and
PROTECT A.700.

2.1 Brief Overview

LED display and a pushbutton switch are located on the front
of the UPS for straightforward monitoring and operation. The
display unit with traffic light function clearly signals the
particular operating condition: normal operation, battery
discharge, fault.

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. Important UPS
data is monitored permanently and transferred to the
computer via USB or the RS232 interface and using the
CompuWatch software.

stations, relatively small-scale telecommunication
equipment and similar devices.

Features of the PROTECT A.:

♦ VI (line – interactive) protection technology
♦ Automatic voltage regulation against mains voltage

deviations (AVR)

♦ Microprocessor control for high reliability
♦ Modern battery management with integrated protection

against exhaust. discharge and overloading

♦ User-friendly display

with optimum legibility

♦ Intelligent monitoring system

with USB and RS232 interfaces

♦ Overvoltage protection (RJ11)

for fax, modem and phone

♦ CompuWatch software for shutdown, status messages

and measurement values for all major operating
systems (incl. Windows, Mac, Linux)

♦ Compact design / without fan

2.2 Principle of Operation

The UPS is connected to a shockproof socket between the
public utility’s mains and the loads to be protected.

Under normal operating conditions, i.e. if PROTECT A. is
supplied with mains voltage, the battery charger will ensure
that the battery is always completely charged.

During this operating status, the loads connected to
PROTECT A. are supplied with voltage via mains filters which
provide effective protection against mains voltage peaks and
high-frequency faults.

In case of sustained mains undervoltage or overvoltage within
defined ranges, the automatic voltage regulator (AVR) further
stabilises the load voltage. As a result, voltage fluctuations in
the public utility’s mains are reduced to a level which is
acceptable for the loads. This is performed without recourse
to the internal energy storage, something which in turn has a
positive effect on battery availability.

The static bypass switch is activated in the event of a mains
failure. The inverter then takes over the voltage supply of the
connected loads, in order to prevent the risk of data loss or
damage to the loads. PROTECT A. supplies voltage until the
battery is discharged or your IT system has been shut down
and switched off properly.

The standby time mainly depends on the connected loads. If
the mains power supply is back to normal values, the UPS will
switch back the loads to mains supply. The battery charger
will then recharge the battery.

For safety reasons (as required by German standards, VDE),
the mains input in the unit will be disconnected by a two-pole
switch in the event of a mains failure. Energy backfeed to the
mains and voltage supply to the pins of the mains connector
are thus reliably avoided.

Furthermore, additional measures ensure effective protection
for the data/network interface.

3.2 Safety Instructions for PROTECT A.

This chapter contains important instructions for the
PROTECT A. UPS. These must be followed during assembly,
operation and maintenance of the uninterruptible power
supply and the batteries.

The UPS is live, and the voltage can be
dangerous. The unit may only be opened by
trained and qualified personnel. Repairs may
only be carried out by qualified customer service
staff!
