Leuze electronic
4.3.1
PWR IN - voltage supply and switching input/output
Attention!
For devices with integrated heating, the supply voltage must be wired with a minimum
0.5 mm² (recommended 0.75 mm²) core cross section. It is not possible to loop the
supply voltage through to other loads!
Notice!
Cables with a core cross section of 0.5 mm² or 0.75 mm² are not available as ready-made
cables from Leuze electronic.

to
PIN 5 of the M 12 connector
PWR IN
for the voltage supply!
Notice!
Programming of the switching input/switching output is performed via module 7 (Switching
input) and module 8 (Switching output). For further information, see also chapter 8.1.7.7,
page 59 ff.
Notice!
The switching input/switching output of the
PWR IN
plug connection is identical to the
SWIN
switching input and
SWOUT
switching output of the
SW IN/OUT
plug connection on the
MS 34 105.
Attention!
Protection class IP 65 is achieved only if the connectors and caps are screwed into place!
