The protective conductor (PE) must be dimensioned in compliance with local installation rules for
equipment with increased leakage currents. As a minimum, it must satisfy one of the following
conditions:
•
The protective conductor is routed so that along its complete length it is protected against
mechanical damage.
•
The protective conductor has a cross-section ≥ 10 mm
•
A second protective conductor with the same cross-section is provided.
•
When establishing the connection using an industrial plug connector according to EN 60309,
as core of a multi-core cable it has a cross-section ≥ 2.5 mm
•
As a core of a multi-core cable, the protective conductor has a cross-section ≥ 2.5 mm
The cable cross-section must be dimensioned in compliance with local installation rules.
The cable cross-sections must be dimensioned in compliance with local installation regulations.
The protective conductor must have the same cross-section as the line conductor of the motor
connection cable.
