Requirements on the installation location

The cabinet units are designed for installation in closed, electrical operating areas in
compliance with EN 61800-5-1. A closed electrical operating area is a room or area
containing electrical equipment that can be accessed by trained personnel only. Access is
controlled by a door or other form of barrier that can be opened only by means of a key or
other tool. The room or area is also clearly marked with appropriate warning notices.
The operating areas must be dry and free of dust. The air supplied must not contain any
electrically conductive gas, vapors, or dust, which could impair operation. It may be
necessary to filter the air supplied to the room where the equipment is installed. If the air
contains dust, filter mats (option M54) can be installed in front of the ventilation grills of the
cabinet doors and also in front of the optional hoods. Option M54 offers additional protection
against water sprayed against the housing from any direction and corresponds to degree of
protection IP54.
The permissible values for climatic ambient conditions must be taken into account.
At temperatures > 40°C (104°F) and altitudes > 2000 m, the devices must be derated.
The basic version of the cabinet units complies with the IP20 degree of protection in
accordance with EN 60529.
Installation is realized in accordance with the dimension drawings supplied. The clearance
between the top of the cabinet and the ceiling is also specified in the dimension drawings.
The cooling air for the power unit is drawn in from the front through the ventilation grills in the
lower part of the cabinet doors. The hot air is discharged through the perforated top cover or
the ventilation grilles in the top cover (with option M13/M23/M43/M54/M78). Cooling air can
also be supplied from below through raised/intermediate floors or air ducts, for example. To
allow this, openings must be made in the 3-section bottom panel or individual bottom panels
must be removed.
According to EN 61800-3, the cabinet units are not intended for use in low-voltage public line
supplies that supply residential buildings. High-frequency interference may occur if it is used
in this type of line supply.
Additional measures (e.g. line filter, option L00) can be fitted for use in the first environment
to EN 61800--3 Category C2.
