7. Starting, operation
GB
Operate the level probe with a shielded cable and earth the shield at least on one
side of the cable, if the cable is longer than 30m (2-wire), or if it is run outside of the
building.
There mus be no differences in potential between medium/tank and the grounding of
the junction box and the control cabinet when the shield of the cable is applied.
Ingress protection per IEC 60529
Please make sure that the ends of cables with flying leads do not allow any ingress of
moisture.

With a line transformer you realise the mandatory galvanic isolation of the voltage
and current supply between hazardous and non-hazardous areas and ensure the
safety connection data.
