Safety claim
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 will be associated with the equipment will 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
