The protective conductor must be connected up both on the mains side
and on the motor side.
On account of leakage currents through the interference-suppression
capacitors, a minimum cross-section of 10 mm² must be used in
accordance with VDE 0160. If mains connections with cross-sections
less than 10 mm² are used, the following measures can be applied.
If the unit is mounted on a grounded mounting surface via a conductive
connection, the protective conductor cross-section can be the same as
that of the supply-cable conductor.
In the case of insulated installation or a poor conductive connection to
the mounting surface, a separate protective conductor with a cross-
section of 10 mm² can be connected up instead of the protective
conductor of the mains connection.
