Internal cabling work is not required for models with multi-pole connection, which makes installation and start-up
on site considerably easier and quicker, reducing the risk of leaks. However, you will require the correspondingly
packaged or assembled cable sets with the following pin assignment:
Input and output signals to the higher-level control (PLC):
12-pole circular plug-in connector M12 x 1.0 - male (acc. to IEC 61076-2-101)
