Cable glands
Requirements for meeting ingress protection:
Only use cable glands within their indicated clamping area (cable diameter suitable for
the cable gland).
Do not use the lower clamping area with very soft cable types.
Only use round 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 ingress protection
For cables with a pronounced cold-flow behaviour the screw connection must be fully
tightened.
