DOK-MOTOR*-MKE*******-PRJ1-EN-E1,44 • 06.97
To meet the explosion requirements, it is necessary to tighten the cable
screwed joints after power and feedback cables are in place.
Tightening torque: 15 Nm
A tightening torque of approximately 15 Nm is achieved if the cable scre-
wed joints are manually tightenend and then followed by two more turns
of a suitable tool (spanner or wrench).
The EExd screwed joints are only permitted with specific cable diameters.
The table below specifies these diameters for screwed joints of the power
and feedback cables.
