6.14 Cable connections

The cable gland must be sealed to ensure that the required protection class is reached.
Requirements for meeting ingress protection
Only use cable glands within their indicated clamping range (cable diameter suitable for
■
EN
the cable gland).
Do not use the lower clamping area with very soft cable types.
■
Only use circular cross-section cables (if necessary, slightly oval in cross-section).
■
Do not twist the cable.
■
Repeated opening/closing is possible; however only if necessary, as it might have a
■
detrimental effect on the protection class.
For cables with a pronounced cold-flow behaviour the screw connection must be fully
■
tightened.
CAUTION!
Seal should be checked for signs of brittleness and, if necessary, replaced.
6.15 Tapered threads (NPT)
Connections with tapered threads (NPT) are self-sealing. It should be checked whether it
may be necessary to seal them additionally with PTFE tape or thread sealant. The threads
must be lubricated with a suitable lubricant before fitting.
Tighten the threads by hand when carrying out the final assembly in the plant. Correspond
to the delivery status of the premounted components. The final tightening and sealing must
be made with a wrench (1.5 to 3 rotations).
