1.3 Earthing and earth fault protection
The AC drive must always be earthed with an earthing conductor connected to the earthing ter-
minal marked with .
The earth leakage current of the drive exceeds 3.5mA AC. According to EN61800-5-1, one or
more of the following conditions for the associated protective circuit must be satisfied:
0) The protective conductor must have a cross-sectional area of at least 10 mm2 Cu or
16 mm2 Al, through its total run.
a) Where the protective conductor has a cross-sectional area of less than 10 mm2 Cu or
16 mm2 Al, a second protective conductor of at least the same cross-sectional area
must be provided up to a point where the protective conductor has a cross-sectional
area not less than 10 mm2 Cu or 16 mm2 Al.
b) Automatic disconnection of the supply in case of loss of continuity of the protective
conductor.
The cross-sectional area of every protective earthing conductor which does not form part of the
supply cable or cable enclosure must, in any case, be not less than:
-2.5mm
2
if mechanical protection is provided or
-4mm
2
if mechanical protection is not provided.
The earth fault protection inside the AC drive protects only the drive itself against earth faults
in the motor or the motor cable. It is not intended for personal safety.
Due to the high capacitive currents present in the AC drive, fault current protective switches
may not function properly.

CAUTION!
Do not perform any voltage withstand tests on any part of the AC drive. There is a
certain procedure according to which the tests must be performed. Ignoring this proce-
dure may result in damaged product.
