Connection to the power supply line is the responsibility of the installer. The customer must install
the protective conductor and the power supply cable through specialised personnel.
Protective ground connection
Connect the system protective ground to the indicator with a yellow-green cable of at least 6mm².
Use the ground screw located under the indicator.
The equipotential conductor from the scale must also be connected to the same grounding point.

refer to the technical power supply characteristics.
Also provide a disconnect switch upstream of the supply line. The disconnect switch must be
accessible during system maintenance operations.

Double insulation cable with 3 coloured inner conductors
(line=brown, neutral=blue, protective ground=yellow-green)
Inner conductors with cross-section from 1.5mm² to 2.5mm²
External sheath diameter from 5 to 10mm
