3.3.1

Important safety precautions

To ensure that the cabinet units operate safely and reliably, they must be properly installed
and commissioned by qualified personnel, taking into account all the warning notices
provided.
In particular, the general and national installation and safety guidelines for high-voltage
installations (e.g. VDE – the Union of German Technical Engineers) as well as the
guidelines relating to the proper use of tools and personal protective equipment must be
observed.
Death, serious injury, or substantial material damage can result if these guidelines are not
observed.
3.3.2

Preparatory steps

On-site requirements
The Cabinet Modules 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.
Derating is required for ambient temperatures greater than 40 °C (104 °F) and installation
altitudes above 1.000 m (Booksize Cabinet Kit) or above 2,000 m (Chassis) - see derating
data for the relevant Cabinet Modules.
The basic version of the cabinet units complies with the IP20 degree of protection in
accordance with EN 60529.
