6.2 Tightening torques
6.2.1 Cable glands
Note
Take care not to damage the cable jacket.
Tightening torques must be adapted to suit the type of cable jacket material in use.
You should refer to the table in order to find the correct tightening torque for any
metal and plastic cable glands that are to be mounted directly on the machine, as
well as for any other screw-type connections (such as adapters).
