interface type C according to EN 50181 are listed in the section "Description" (see page 34,
"Cable connection"NXPLUS C).
Please select the tightening torque of the bolted joint "cable T-plug - bushing" according to the
specifications of the respective cable T-plug manufacturer.
If there are no specifications from the cable T-plug manufacturer's side, please tighten the
bolted joint with 50 Nm.
