the cabinet unit. 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 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 cabinet 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
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
