1. Introduction

The Rittal PMC UPS 6kVA Series is an uninterruptible power
supply incorporating double-converter technology. It provides perfect
protection specifically for Novell, Windows NT and UNIX servers.

The double-converter principle eliminates all mains power
disturbances. A rectifier converts the alternating current from the
socket outlet to direct current. This direct current charges the batteries
and powers the inverter. On the basis of this DC voltage, the inverter
generates a sinusoidal AC voltage which permanently supplies the
loads.

Computers and periphery are thus powered entirely
independently of the mains voltage. In the event of power failure, the
maintenance-free batteries power the inverter. This means an end to
the switchover times from mains to battery operation which cannot be
avoided on other systems.

2. Safety Instructions

PLEASE READ THROUGH AND FOLLOW THE USER
MANUAL AND THE SAFETY INSTRUCTIONS BEFORE
INSTALLING THE UNIT AND STARTING IT UP!

Transport

• Please transport the UPS system only in the original packaging (to

protect against shock and impact).

Set-up

• Condensation may occur if the UPS system is moved directly from

a cold to a warm environment. The UPS system must be absolutely
dry before being installed. Please allow an acclimatisation time of
at least two hours.

• Do not install the UPS system near water or in damp environments.

• Do not install the UPS system where it would be exposed to direct

sunlight or near heat.

• Do not block off ventilation openings in the UPS system’s housing.

Installation

• Please note the special installation aspects for the permanently

connected units Rittal PMC UPS 6kVA in Chapter 4 „Installation
and Start Up“.

• The building wiring socket outlet (shockproof socket outlet) must

be easily accessible and close to the UPS system.

30

• Please use only VDE-tested, CE-marked power cables to connect

the loads to the UPS system.

• Do not connect domestic appliances such as hair dryers to UPS

output sockets.

• Do not connect appliances or items of equipment which would

overload the UPS system (e.g. laser printers) to the UPS outlet
socket.

• Place cables in such a way that no one can step on or trip over

them.

Operation

• Do not disconnect the mains cable on the UPS system or the

building wiring socket outlet (shockproof socket outlet) during
operations since this would cancel the protective earthing of the
UPS system and of all connected loads.

• The UPS system features its own, internal current source

(batteries). The UPS output sockets may be electrically live even if
the UPS system is not connected to the building wiring socket
outlet.

• In order to fully disconnect the UPS system, first press the Standby

switch then disconnect the mains lead or, on the permanently
connected unit Rittal PMC UPS 6kVA, isolate the incoming
feeder.

• Ensure that no fluids or other foreign objects can enter the UPS

system.

Maintenance, servicing and faults

• The UPS system operates with hazardous voltages. Repairs may be

carried out only by qualified maintenance personnel.

31

• Caution - risk of electric shock. Even after the unit is disconnected

from the mains power supply (building wiring socket outlet),
components inside the UPS system are still connected to the
battery and are still electrically live and dangerous. Before carrying
out any kind of servicing and/or maintenance, disconnect the
batteries and verify that no current is present.

• Only persons adequately familiar with batteries and with the

required precautionary measures may exchange batteries and
supervise operations. Unauthorised persons must be kept well
away from the batteries.

• Caution - risk of electric shock. The battery circuit is not isolated

from the input voltage. Hazardous voltages may occur between the
battery terminals and the ground. Before touching, please verify
that no voltage is present!

• Batteries may cause electric shock and have a high short-circuit

current. Please take the precautionary measures specified below
and any other measures necessary when working with batteries:

- remove wristwatches, rings and other metal objects

- use only tools with insulated grips and handles.

• When changing batteries, install the same number and same type of

batteries.

• Do not attempt to dispose of batteries by burning them. This could

cause battery explosion.

• Do not open or destroy batteries. Escaping electrolyte can cause

injury to the skin and eyes. It may be toxic.

• Please replace the fuse only by a fuse of the same type and of the

same amperage in order to avoid fire hazards.

• Do not dismantle the UPS system.

3. Indicators and Operating Controls

3.1 Front Panel

Figure 1: Operating and display panel

Switch Function

ON - Switch 1. Turn on UPS system:

By pressing the ON-Switch „I“ the UPS system is turned on.

2. Deactivate acoustic alarm:
By pressing this switch an acoustic alarm can be
deactivated.

33

Standby­Switch

The UPS system switches to Standby mode when the
Standby button „ “ is pressed. It is then switched to
Bypass and the inverter is off. The output sockets are
supplied with voltage via the bypass if the mains
power supply is available.

Display Function

LINE LED 1. The green LINE LED lights up if mains voltage is

applied to the UPS input.

2. LINE_LED blinks when the phase and neutral

conductor have been reversed at the input of the
UPS system.

3. If LINE-LED and BATTERY-LED light up, the

mains power supply is out of tolerance.

BATTERY­LED

BYPASS­LED

INVERTER

-LED

FAULT­LED

The orange-coloured BATTERY-LED lights up when
the mains power supply has failed and the inverter is
being powered by the batteries.

The orange-coloured BYPASS LED lights up when
the UPS system is supplying voltage provided by the
mains power supply system via the bypass.

The green INVERTER LED lights up if the inverter of
the UPS is operating and supplying the UPS output
with energy.

The red FAULT-LED lights up and an acoustic
warning signal is issued every second when the UPS is
overloaded (load exceeds the maximum power of the
UPS).

The red FAULT LED lights up and an acoustic
warning signal is issued when the UPS system is in
fault condition. Press the Standby switch in order to
turn off the warning tone.
