servicing. Maintenance is intended to ensure that the electrical installation remains in the
specified condition. Dirt and contamination must be removed regularly and parts subject to
wear replaced.
The following points must generally be observed.

Cleaning

Dust deposits
Dust deposits inside the cabinets must be removed at regular intervals (or at least once a
year) by qualified personnel in line with the relevant safety regulations. The unit must be
cleaned using a brush and vacuum cleaner, and dry compressed air (max. 1 bar) for areas
that cannot be easily reached.
Ventilation
The ventilation openings in the cabinets must never be obstructed. The fan must be checked
to make sure that it is functioning correctly.
Cable and screw terminals
Cable and screw terminals must be checked regularly to ensure that they are secure in
position, and if necessary, retightened. Cabling must be checked for defects. Defective parts
must be replaced immediately.
Note
The actual intervals at which maintenance procedures are to be performed depend on the
installation conditions (cabinet environment) and the operating conditions.
