Additional Cautions
CAUTION
The PowerXL DG1 AC drive must always be grounded with
an grounding conductor connected to the grounding terminal
marked with. The ground leakage current of PowerXL DG1
exceeds 3.5 mA AC. According to EN61800-5-1, one or more
of the following conditions for the associated protective
circuit shall be satisfied:
a) The protective conductor shall have a cross-sectional
area of at least 10 mm
2
Cu or 16 mm
2
Al, through its
total run.
b) Where the protective conductor has a cross-sectional
area of less than 10 mm
2
Cu or 16 mm
2
Al, a second
protective conductor of at least the same cross-sectional
area shall be provided up to a point where the protective
conductor has a cross-sectional area not less than
10 mm
2
Cu or 16 mm
2
Al.
c) Automatic disconnection of the supply in case of loss of
continuity of the protective conductor. The cross-
sectional area of every protective grounding conductor
that does not form part of the supply cable or cable
enclosure shall, 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 ground fault protection inside the AC drive protects
only the drive itself against ground faults in the motor or
the motor cable. It is not intended for personal safety.
The ground fault protection inside the AC drive protects
only the drive itself against ground 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.
Do not perform any voltage withstand tests on any part
of PowerXL DG1. There is a certain procedure according
to which the tests shall be performed. Ignoring this
procedure may result in damaged product.
