Avoid damaging the cable jacket.
Adapt the tightening torques to the cable jacket materials.
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).
