Important (Note)
Ingress protection IP 66 / 67 is only achieved by installing the black neoprene gasket between
the cable gland and the housing and by observing the tightening torque for the cable gland of
3 Nm (Position 2).
Cables must be protected against extreme mechanical loads (caused by tension, torsion,
crushing, etc.). Even under operating conditions, it must be ensured that the cable entry
remains hermetically sealed. The customer must provide a strain relief device for the cable.
Maintenance
Check the glands during each maintenance session. If the cable is slack, retighten the cap(s) of
the glands. If it is not possible to retighten them, the gland will need to be replaced.
