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 UL notes.
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. Strictlyobserve thenotes onthe
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!
