General safety and application notes for Lenze controllers
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 a 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. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation.
Note for UL approved systems with integrated controllers: UL warnings are notes that only
apply to UL systems. The documentation contains special information about UL.
Safety functions
Some variants of the controllers support safety functions (e. g. "safe torque off", formerly
"safe standstill") according to the requirements of appendix I no. 1.2.7 of the EC Directive
"Machinery" 98/37/EC, EN 954-1 category 3 and EN 1037. The notes on the safety
instructions in the documentation of the variants must be strictly observed.
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!
Waste disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.
The product-specific safety and application notes given in these Operating Instructions
must be observed!
