l The power distribution system must be installed by qualified
personnel only.
l Only after expert installation may the assembly be connected to a
power supply.
l The assembly is only suitable for use at safety extra-low voltage
(DC 24 V).
l Connection to higher or not reliably disconnected voltages may be
hazardous or cause damage.
l The max. total current of the SVS09 system must not be exceeded.
l In each load circuit the cable cross sections and the current rating
of the protective device must be selected according to the rating
of the connected load.
l The technical data of the circuit breakers used must be observed.
l According to “Machinery Directive 98/37/EG and EN 60204-1,
Machine Safety” special precautions have to be taken in machinery
(e. g. use of a safety PLC) to prevent inadvertent start-up of machinery
parts. In the event of a failure (short circuit/overload) the load circuit
will be disconnected by the circuit breaker.
l After tripping of the circuit breaker and before reset the cause of
tripping (short circuit or overload) must be remedied.
l The international standards (e. g. DIN VDE 0100 for Germany) must
be observed with respect to installation and selection of cables.
