Safety in case of faults
Ì The operating voltage U
B
is reverse polarity protected.
Ì The contacts OA/OB are short circuit proof.
Ì The switch detects a short circuit between OA/OB and U
B
.
Ì A short circuit between OA and OB is detected by the switch.
Ì A short circuit in the cable can be excluded by laying the cable with protection.
Fuse protection for power supply
The power supply must be provided with fuse protection depending on the number
of switches and current required for the outputs. The following rules apply:
Max. current consumption of an individual switch I
max
I
max
= I
UB
+ I
DIA
+ I
OA+OB
I
UB
= Switch operating current (50 mA)
I
DIA
= Monitoring output load current (max. 200 mA)
I
OA+OB
= Load current of safety outputs OA + OB (2 x max. 400 mA)
