Ventilation; During Transport And Storage - Eaton Magnefix MD4 User Manual

Magnefix MD4
3.2.2

Ventilation

Magnefix MD4 switchgear does not require ventilation.
However, air circulation around the switchgear may carry
dust liable to deposit on the installation.
Take the following precautions in order to prevent
undesirable air circulation:
General

Ensure that the switchroom doors provide a good seal
in order to prevent draughts.

If located alongside a busy motorway or in the vicinity
of a farm or chemical plant, take action to minimise the
quantity of polluted air entering through the ventilation
slots.
Room without a transformer

Avoid air circulation inside the room; the switchgear
does not need any cooling.

If you decide on having a ventilation slot, position it
low in the room.
Room with a transformer

Position the ventilation slots such that the air flow
intended for transformer ventilation does not pass over
the switchgear.

If ventilation air flow over the switchgear cannot be
avoided, install an adequate dust guard.

Keep the switchgear thoroughly clean.
3.2.3

During transport and storage

If the switch panels are stored temporarily prior to
installation, or during transport:

Do not unpack the switch panels;

Store the switch panels vertically in a dry and dust-
free area;

Ensure that the transportand 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.
