Assembly
Assembly of the adapter w hich is used for the migration of the round plug c onnectors from M8 to M12
should preferably be carried out with commercially available tools.
The stated tightening torques must be used for tightening the hexagonal nut on the M8 plug connector or on the
M12 socket. Please refer to the technical data for the tightening torques.

In order to ensure a secure, sealed and vibration-proof connection, the
round plug connectors, which are equipped with a hexagonal threaded ring
M8 ↔ SW 9, M12 ↔ SW13), should be tightened with a special torque
wrench.
