2.7 Safety
Our products normally become part of larger systems or installations. The information below is intended to
help you integrate the product into its environment without dangers to humans or material/equipment.
DANGER
Non-observance of the instruction manual
Measures for the prevention of dangerous faults or errors may be rendered ineffective or new
hazard sources created.
Thoroughly read the instruction manual
Take particular heed of the hazard warnings
Information
To achieve a high degree of conceptual safety in planning and installing an electronic controller,
it is essential to exactly follow the instructions given in the manual because wrong handling could
lead to rendering measures against dangers ineffective or to creating additional dangers.
Project Planning
Recommendation for 24V DC supply: Generate as electrically safely separated low voltage.
Suitable devices include split-winding transformers built in compliance with European Standard EN
60742 (corresponds to VDE 0551).
Power breakdowns or power fades: the program structure is to ensure that a defined state at restart
excludes all dangerous states.
Emergency-off installations must comply with EN 60204/IEC 204 (VDE 0113). They must be
operative at any time.
Safety and precautions regulations for qualified applications have to be complied with.
Please pay particular attention to the notices of warning which, at relevant places, will make you
aware of possible sources of dangerous mistakes or faults.
Relevant standards and VDE regulations are to be complied with in every case.
Control elements are to be installed in such a way as to exclude unintended operation.
Lay control cables such that interference (inductive or capacitive) is excluded if this interference
could influence controller operation or its functionality.
Maintenance and Servicing
Precautions regulation VBG 4.0 to be observed when measuring or checking a controller after
power-up. This applies to section 8 (Admissible deviations when working on parts) in particular.
Repairs must be carried out by specially trained Kuhnke staff only (usually in the main factory in
Malente). Warranty expires in every other case.
Only use parts approved of by Kuhnke. Only genuine Kuhnke modules must be used in modular
controllers.
Modular systems: always plug or unplug modules in a power-down state. You may otherwise
damage the modules or (possibly not immediately recognisably!) inhibit their functionality.
Always dispose of (rechargeable) batteries as hazardous waste.
