Wiring

For devices with a separate sensor (type code extensions (2) /60 or /65), the
transmitter and detached sensor are matched to one another at the factory! 
When connecting the components, please note that the serial number of the
external sensor (marked on the label attached to the connecting cable) must
match the serial number marked on the nameplate of the transmitter!

Caution:
On devices with a 
separate sensor 
and M12 plug/
socket
connectors, the 
screw terminals are 
sealed inside the 
device. 
Removal of this 
sealing will 
invalidate the 
warranty!
