8. Electrical connection
WARNING
If there is a mistake, loss of the safety function due to incorrect connection.
Ì
Monitoring outputs must not be used as safety outputs.
Ì
Lay the connecting cables with protection to prevent the risk of short circuits.
NOTICE
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì
All the electrical connections must either be isolated from the mains supply by a safety transform-
er according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equiv-
alent isolation measures.
Ì
All electrical outputs must have an adequate protective circuit for inductive loads. The outputs
must be protected with a free-wheeling diode for this purpose. The switch-on current may have to
be limited for capacitive loads.
Ì
Protect the 24 V area with a suitable external fuse.
Ì
Make sure that the power supply unit can provide quadruple the nominal current of the external
fuse in order to guarantee reliable triggering in case of a fault.
