3.1
Environmental requirements
The switchroom in which the switchgear is set up must
comply with the following:
All safety regulations applicable locally;
The requirements set out in the chapter on safety
The requirements in this paragraph.
3.1.1
Climate
In accordance with IEC 62271-1 par. 2.1.1 the climate in
the switchroom must comply with the following:
Humidity:
90% Maximum relative humidity over a period
of 1 month.
In new buildings it is essential to dry out the
area before installing the system.
Temperature:
M40
C, measured over a period of
24 hours.
Average not more than +35
C.
Minimum not less than -5
C.
The room must be free from dust, corrosive or
flammable gases and salts.
If the installation has to operate in a less suitable
operating environment it may be necessary to take special
precautions. Users should consult Eaton.
3.1.2
Room for extension
If necessary, reserve sufficient space for later extension of
the installation or the addition of auxiliary equipment.
3.1.3
Floor
The floor of the operating area should comply with the
following:
The floor must be flat and level to within ± 2mm per
metre length of the intallation;
The floor must not have any raised areas (bumps)
though indentations are permitted;
The floor must be of adequate strength.
Sections or foundation frames set in the floor can be used
as the support surface for the installation. The area
between the floor sections and the panel must always be
filled in with filler plates to create a suitable support
surface.
Details on the dimensions and weight of the switchgear
can be found in the floor plan drawing in the information
pack.
3.1.4
Floor plan
Fig. 3-1 gives an example of how equipment is set up. For
some other floor plans, refer to 9.2 of APPENDIX. Further
information is available from the information pack that
includes this manual.
3.1.5
During transport and storage
If the switchgear panels are stored temporarily prior to

dust-free area;
Ensure that the transport and storage environment
complies as far as possible with the requirements of
IEC 62271-1, par. 2.1.1;
Avoid condensation caused by rapid temperature
changes.
NOTE
If the installation is kept in poor conditions in the
open air, corrosion and a reduction in the level of
insulation may result.
