11.2 Maintenance
Inverter chassis units
510 Operating Instructions, 07/2016, A5E00331449A
Dust deposits inside the chassis 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.
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.
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 and the operating conditions.
