2.2 System Description

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

The power section of the rectifier converts the mains voltage
to DC voltage for supplying the inverter. The circuit
technology used (PFC) enables sinusoidal current
consumption and therefore operation with little system
disturbance. A separate, second rectifier (charging REC set
up using switch mode power supply technology) is
responsible for charging or trickle-charging the battery
connected in the intermediate circuit. The configuration of this
charging REC means the harmonic content of the charging
current for the battery is almost zero, so the service life of the
battery is increased even more. The inverter is responsible for
converting the DC voltage into a sinusoidal output voltage. A
microprocessor-controlled control system based on pulse­width modulation (PWM) in conjunction with an extremely
quickly pulsating IGBT power semiconductors of the inverter
guarantee that the voltage system on the protected busbar is
of the highest quality and availability.

In the event of mains faults (e.g. current failures), the voltage
continues to be supplied from the inverter to the load without
any interruption. From this point onwards, the inverter draws
its power from the battery instead of the rectifier. No switching
operations are necessary; this means there is no interruption
in the supply to the load.

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.

The automatic bypass serves to increase the reliability of the
supply further. It switches the public mains directly through to
the load if there is an inverter malfunction. As a result, the
automatic bypass represents an extra passive redundancy for
the load.

3.2 Safety Instructions for PROTECT C.

This chapter contains important instructions for the
PROTECT C. UPS and its external battery modules (special
accessories). These must be followed during assembly,
operation and maintenance of the uninterruptible power
supply and the battery systems (internal and, if appropriate,
external as well).

(special accessories):

♦ Do not dismantle the UPS!

(The UPS does not contain any parts that require regular
maintenance. Bear in mind that the warranty will be
invalidated if the unit is opened!)

♦ Do not install the unit in direct sunshine or in close

proximity of heaters!

10

♦ The unit is designed to be installed inside in heated

rooms. Never install the housing in the vicinity of water or
in an excessively damp environment!

♦ Condensation may occur if the UPS is brought from a

cold environment into the room where it is to be installed.
The UPS must be absolutely dry prior to start-up. As a
result, leave it to acclimatise for at least two hours.

♦ Never connect the mains input to the UPS output, and

vice versa!

♦ Ensure that no fluids or foreign bodies can penetrate the

housing!

♦ Do not block the air vents of the unit! Keep children away

from the unit and ensure that objects are never inserted
through the air vents!

♦ Do not connect household appliances such as hairdryers to

theUPS! Also take care when working with motor loads. It is
essential to avoid back-feeding the inverter, e.g. if the load is
intermittently operated in regenerative mode.

♦ The mains connection should be near the unit and easily

accessible to facilitate disconnecting the AC input or
pulling out the plug!

♦ During operation, do not disconnect the mains connection

cable from the UPS or from the socket outlet in the building
(shockproof socket), otherwise the protective grounding of the
UPS and all the loads connected to it will be cancelled.

Danger! Electric shocks!

Even after the mains voltage has been
disconnected, the components within the UPS
remain connected to the battery and can thus
cause electric shocks. It is therefore imperative to
disconnect the battery circuit before carrying out
any maintenance or repair work!

If it is necessary to replace the battery or carry
out maintenance work, this must be done by or
under the supervision of a specialist familiar with
batteries and the necessary safety precautions!

Only authorised persons are allowed in the
vicinity of the batteries!

11

When replacing the batteries, the following must be observed:

Never open or damage batteries. (Electrolyte

Take the following safety precautions when working with the
batteries:

♦ Take off watches, rings and other metallic objects!
♦ Always use tools with insulated handles!

Do not switch loads on and off using the UPS
main switch. Do not use multiple outlet adapters

i

with a central on/off switch, in order to avoid peak
inrush currents.

Switch OFF the UPS using its main switch “OFF” if you do not
intend to use it for some time. PROTECT C. must be switched
off every evening if the electricity supply in your company is
switched off every night. Otherwise, the battery will be
discharged (assumed power failure). Frequent and complete
discharging of the battery leads to a shorter service life of the
battery and should therefore be avoided!

For personal safety reasons, never switch on the
main switch when the mains connector of
PROTECT C. is disconnected!

5 Commissioning

5.1 Mechanical Set-Up

Note the following points when setting up the UPS system
and its external battery units (special accessories):

♦ The contact surface must be smooth and level. It must

also be sufficiently strong and sturdy to avoid vibration
and shock loads.

♦ Make sure the mounting is able to support the weight:

This is particularly important in conjunction with external
battery units (special accessories).

♦ Set up the units so that adequate air circulation is

assured. There must be at least 100 mm clearance at the
back for ventilation purposes. Do not block the intake
openings on the front and, if present, on the side of the
unit. There must be a gap of at least 50 mm here.

♦ Set up external battery units (special accessories) to the

side of the UPS system. To ensure the greatest possible
mechanical stability, you should not set up the external
battery unit(s) above or below the UPS system.

♦ Avoid extreme temperatures! We recommend an ambient

temperature of 15 °C to 25 °C in order to maximise the
service life of the batteries. Do not expose the units to
direct sunlight or operate them close to other heat
sources such as radiators.

♦ Protect the units against external effects (in particular

moisture and dust). In this regard, please also refer to the
instructions in chapter 4.2, page 20 in these operating
instructions.

If you transport the unit from a cold room into a warm one, or
if the room temperature suddenly drops then condensation
may form inside the unit. To avoid any damage due to
condensation, leave the unit to acclimatise for 2 hours before
you switch it on.

25

5.2 External Battery Expansions

To achieve longer backup time, it is possible to connect multi­battery packs. Connect exclusively
together:

voltage on the UPS system can be adjusted with the software
“CompuWatch” in steps of 220 Vac, 230 Vac and 240 Vac.

Turn on the PROTECT C. to the mains

1. Now connect the input of the UPS to the mains
connection cable provided and plug the mains
connector into a suitable shockproof socket. Avoid
using extension cables and / or adapters. In
particular in the case of high-capacity types, ensure
that the fusing in your sub-distribution is adequately
dimensioned:The 3kVA system for example requires
its own connection with a 16 A fuse. No other loads
should be connected to this circuit!

2. Activate the mains input circuit breaker. If
necessary switch it to “ON”.

Once you have connected the UPS to a suitable mains
connection, you can start operation using the UPS main
switch (see also "Electrical Start-Up" on page 27). Normally,
the UPS operates continuously. The UPS now supplies the
output with voltage, this being signalled by the symbols mains
(LED Line) and rectifier (LED Inverter) symbols which light up
permanently.

This is often referred to as “online” mode. It offers the greatest
protection, in particular when there are mains fluctuations and
mains failures, because the loads are supplied continuously
with voltage with no interruptions in this operating mode.

The mains is not within the required tolerance range or has
failed. In this case power is supplied to the inverter from the
charged battery without interruption. The power supply to the
loads is therefore also ensured in the event of a mains failure.
This drains the capacity of the battery and it is discharged. This
status is signalled by the battery symbol (LED Battery) lighting
up, as well as an intermittent acoustic signal every 4 seconds
and every second before switching off. This can be suppressed
by pressing the “Alarm off” button. With decreasing battery
capacity the alarm is activated automatically. Depending on the
expansion level, age and condition of the battery and in
particular on the load to be supplied, the standby time can vary
from a few minutes to several hours.

range once more, the rectifier and the battery charger switch
back on automatically. The rectifier then continues supplying
the inverter and the battery charger takes over charging the
battery.

5.3.3 Bypass Operation

If the inverter is overloaded or if overtemperature is detected,
e.g. also if an inverter defect is detected, voltage is supplied
to the load via the bypass that switches on automatically. This
is signalled by the bypass symbol.

This function is also referred to as passive redundancy. It
protects against total failure of the voltage supply on the
protected busbar, however in the operating status that is now
attained, mains faults would have a direct effect on the load.

As a result, the electronics continuously attempt to switch
back to "online" / normal operating status (e.g. when the
overload or overtemperature no longer applies).

The bypass is a mechanical link that switches extremely

5.3.4 Unit Overload

The load on the UPS should never exceed the specified rated
load of the unit. If a unit overload occurs nevertheless (from
105% ± 5% of the specified unit rated load) the fault LED is
turned on accompanied with a signal tone (twice per second).
The connected loads continue to be supplied for a certain
time depending on the level of the overload. However, the
connected load must be reduced without delay.

Non-observance of the "Unit overload" condition may cause
the total loss of all UPS functions!

Also avoid short-term unit overloads, which may, for example,
occur when connecting a laser printer or laser fax machine.
Do not connect any household appliances or machine tools to
the UPS.

As a rule, if there has never been an overload during normal
operation, there will not be one during battery operation
either.

Never connect or switch on any additional loads
to the UPS if there is a mains failure, i.e. if the
UPS is working in emergency power operation!

The signalling of the fault LED in combination
with a continuous alarm points out a switching
of fault. Follow the instructions in chapter 6.

7 Maintenance

The PROTECT C. consists of advanced and resistant
components. To guarantee a continuous and high availability
it is recommended to check the unit (especially the batteries
and the fans) in regular intervals (at least every 6 months).

CAUTION:

Follow safety and security regulations
unconditionally!

7.1 Charging the Battery

The battery is automatically charged when the mains is
present, irrespective of the operating mode. This is signalled
by the "Line" LED lighting up (see also chapter 6).

The complete charging time of the battery after a length
discharge period depends, above all, on the number of
additional external battery units.

Charging time up to 90% of rated capacity

Only with internal UPS battery approx. 5 hours
One additional battery unit approx. 24 hours
Two additional battery units approx. 40 hours

7.2 Maintenance

The following maintenance work should be performed:

Task Interval Described in
Visual check 6 months Chapter 7.2.1
Battery/fan check 6 months Chapters 7.2.2 / 7.2.3

7.2.1 Visual Check

When visually checking the unit, check whether:
♦ there is any mechanical damage or foreign bodies can be

found in the system,

♦ any conductive dirt or dust has accumulated in the unit,
♦ accumulation of dust affects heat supply and dissipation.

39

CAUTION:

PROTECT C. must be disconnected from the
power supply prior to carrying out the
following work.

If large quantities of dust have accumulated, the unit should,
as a precaution, be cleaned with dry compressed air, in order
to ensure adequate heat dissipation.

The intervals at which visual checks should be performed are
largely determined by the site conditions.

7.2.2 Checking the Battery

Progressive ageing of the battery system can be detected by
regular capacity checks. Every 6 months, perform
measurements to compare the achievable standby times, e.g.
by simulating a mains failure. In this case, the load should
always have approximately the same capacity demand.
Please contact our hotline if the time drops drastically
compared to the previous measurement (see page 4).

7.2.3 Fan Checking

Regularly check the fans for dust build-up and noticeably
untypical noise development. Clean the intake openings if
they are blocked. Contact our hotline if a fan is running
unusually loud or irregularly (see page 4).

8.1 Storage

Long storage times without char
lead to permanent damage of the battery.

If the battery is stored at room temperature (20° C to 30° C) it
will automatically discharge at a rate of 3 - 6% per month due
to internal reactions. Storing the battery at temperatures
above room temperature should be avoided. A high storage
temperature also means greater battery self-discharge.

Batteries that are stored at room temperature should be
recharged every six months to maintain their full capacity and
service life.
