5.10 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
■
the cable gland).
Ensure proper clamping range is met when using very soft cables.
■
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.

Ensure transition does not exceed 175 °C [350 °F] and is a minimum
