Operation
If necessary, systems including controllers must be equipped with additional
monitoring and protection devices according to the valid safety regulations (e.g.
law on technical equipment, regulations for the prevention of accidents). The
controller can be adapted to your application. Please observe the corresponding
information given in the documentation.
After the drive controller has been disconnected from the voltage supply, all live
components and power connections must not be touched immediately because
capacitors can still be charged.
All protection covers and doors must be shut during operation.
Maintenance and service
The controllers do not require any maintenance if the prescribed conditions of
operation are observed.
If the ambient air is polluted, the cooling surfaces of the controller may become
dirty, or the air vents of the controller may be obstructed. Therefore, clean the
cooling surfaces and air vents periodically under these operating conditions. Do
not use sharp or pointed tools for this purpose!
Disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled
PCBs.
The product-specific safety and application notes given in these instructions
must be observed!
