Informations
This symbol draws your attention to additional information concerning the use
of the described product. This may include cross references to information
found elsewhere (e.g. in other manuals).
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
•
24 VDC power 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.
•
Because the Safety bus coupler use capacities for voltage equalization , it is recomended to
use line circuit breakers with characteristic B or C.
