3. SETTING UP THE SYSTEM

3.1 Introduction

3.1.1

Transport

Transport for the Magnefix switchgear can be arranged by
Eaton. Detailed instructions are beyond the scope of this
manual. Please contact Eaton Service if necessary. You
will find the address and telephone number on the title
page of this manual.
C
AUTION
Transport the fuses in appropriate (original)
packing only.
The switchgear can be installed by the user's authorised
personnel.
This chapter contains general information on transporting
and setting up Magnefix MD4 switchgear and on
connecting the cables.
3.1.2

Environmental requirements

The switchroom in which the switchgear is set up must
comply with the following:

all safety regulations in force locally;

the requirements set out in the chapter on safety;

the requirements in this paragraph.

3.2 General

3.2.1

During operation

Climate
In accordance with IEC 62271-1 par. 2.1.1 the climate in
the switchroom must comply with the following
requirements:

Humidity:
maximum 90% relative over a period of 1 month. In
new buildings it is essential to dry out the area before
installing the system.

Temperature:
 maximum +40°C, measured over a period of 24
hours.
 average not more than +35°C.
 minimum not less than - 25°C.

The room must be free from dust, corrosive or
flammable gases and salts.
The minimum temperature for Magnefix switchgear with P
panel must not be lower than -5° C.
If the Magnefix switchgear is installed in a switchroom
where unfavourable environmental conditions prevail,
special precautions must be taken to counteract discharges
and the attendant accelerated ageing of the switchgear.
Factors adversely affecting switchgear service life are:

A combination of dust and moisture: installation in
areas of high relative humidity, high groundwater level
or in areas abounding in water;

Temperature variations within the switchroom (which
are liable to cause condensation);

Presence of corrosive substances, for example in the
proximity of chemical plants, farms or alongside large
motorways;

A salty atmosphere; for example, in a coastal region.

Air currents, for instance caused by draughts or
transformer ventilation air, carrying dust liable to
deposit on the switchgear.
The sections that follow describe the main steps that are
required to be taken in order to keep the Magnefix
switchgear in a proper (and therefore reliable) condition for
as long as possible.
