Safety instructions 2
General safety and application notes for Lenze controllers
Safety functions
Special controller variants support safety functions (e.g. "safe torque off", previously "safe
standstill") according to the requirements of Annex I No. 1.2.7 of the EC Directive
"Machinery" 98/37/EC, IEC 61508, EN 954−1 and EN 1037. Strictly observe the notes on
the safety functions given in the documentation for the respective variants.
Maintenance and servicing
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!
