Service and maintenance

5.1

Maintenance

The purpose of maintenance is to maintain the specified condition of the Power Module. Dirt
and pollution must be regularly removed, wearing parts must be replaced. The Power
Module predominantly comprises electronic components. In addition to the fan or fans, the
device hardly has any components that are subject to wear or that require service or
maintenance.
The following points must always be carefully observed.
Dust deposits
Dust deposits inside the Power Module must be removed at regular intervals 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. When using a vacuum cleaner, this must comply with ESD equipment rules.
Ventilation
When installing the devices in a cabinet, make sure that the cabinet ventilation slots are not
obstructed. The fan must be checked to make sure that it is functioning correctly.
If dirt filters are used, the specified replacement intervals must be observed.
Cables and screw terminals
Cables and screw terminals must be checked regularly to ensure that they are secure, and if
necessary, retightened. Retighten if necessary. The wiring must be checked for damage.
Defective parts must be replaced immediately.
Note
The actual maintenance intervals depend on the installation and operating conditions.
