Service and maintenance for Chassis format components

Maintenance is intended to ensure that the equipment 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.
Dust deposits
Dust deposits inside the device must be removed at regular intervals (or at least once a
year) by qualified personnel in line with the relevant safety regulations. The device must be
cleaned using a brush and vacuum cleaner. Areas that cannot be easily reached must be
cleaned with dry compressed air (max. 100 kPa).
Ventilation
The ventilation openings in the devices must never be obstructed. The fans must be checked
to make sure that they are 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 details,
