Cleaning

Dust deposits
Dust deposits inside the cabinet unit 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 cabinet 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
Maintenance intervals
The actual intervals at which maintenance procedures are to be performed depend on the
installation conditions (cabinet environment) and the operating conditions.
Siemens offers its customers support in the form of a service contract. For further details,
