Additional cautions
CAUTION
The PowerXL Series AC drive must always be grounded
with an grounding conductor connected to the grounding
terminal marked with. The ground leakage current of
PowerXL Series 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
•
4 mm
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 Series Drive. There is a certain
procedure according to which the tests shall be
performed. Ignoring this procedure may result in
damagedproduct.
