8.5
Back-Up Fuse
• Provide suitable back-up fuses, see chapter 5 "Technical Data".
8.6
Back-up Fuses for Auxiliary Circuits
• Basically, auxiliary circuits must be short-circuit protected using 10 A gG.
8.7
Intrinsically safe circuits
• In intrinsically safe circuits only insulated cables and conductors with a test voltage of
AC 500 V and a minimum quality of HO5 are permitted.
• The diameter of individual conductors must not be less than 0.1 mm; this also applies
to the individual wires of finely stranded conductors.
• Ex i electric circuits are connected to blue terminal blocks.
• The overload protection of the consumers must be performed independently of the
back-up fuse.

Operation
10.1 Function
Safety switches ensure the obligatory isolation of energy supply during cleaning and
repair work at the machines and installations. Usual preparatory work such as removal of
fuses or disconnection of motors, which can be performed only by electrically skilled
persons, is no longer required.
WARNING
Check the device before commissioning!
To ensure correct operation, check the device before commissioning.
