The information in the safety claim of the equipment documentation is intended to ensure that
equipment is properly installed in order to maintain it in a condition.
It is assumed that everyone who would be associated with the equipment should be familiar with
the contents of that safety section, or this safety guide.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of
the equipment (e.g. the input terminal). Failure to obverse warning notices, incorrect use, or
improper use may endanger personnel and equipment and course personal injury or physical
damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper
storage, installation and commissioning, and on careful operation, maintenance and servicing.
The operating manual for the equipment gives instructions for its installation, commissioning, and
operation. However, the manual cannot cover all conceivable circumstances or include detailed
information on all topics. In the event of questions or specific problem, do not take any action
without proper authorization. Contact the appropriate WB technical sales office and request the
necessary information.
