3.3.2 Preparation

On-site requirements

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 which can be accessed by trained personnel only. Access is

controlled by a door or other form of barricade which can be opened only by means of a key

or other tool. The room or area is also clearly signed 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 installation room. If the air contains dust, filter mats

(option M54) can be installed in front of the ventilation grilles in the cabinet doors and also in

front of the hoods, if necessary. 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.

The built-in units are installed in accordance with the dimension drawings supplied. The

clearance between the top of the cabinet unit and the ceiling is also specified on the

dimension drawings.

The cooling air for the power unit is drawn in from the front through the ventilation grilles in

the lower part of the cabinet doors. The warmed air is expelled 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 floors or air ducts, for example. To allow

this, you have to create openings in the 3-section bottom plate.

According to EN 61800-3, the cabinet units are not suitable for use in low-voltage public

networks that supply residential buildings. High-frequency interference may occur if it is used

in this type of network.

Additional measures (e.g. line filter, option L00) can be fitted for use in the first environment

to EN 61800--3 category C2.

Unpacking the cabinets

Check the delivery against the delivery note to ensure that all the items have been delivered.

Check that the cabinet is intact.

The packaging material must be discarded in accordance with the applicable country-specific

guidelines and rules.
