According to EN61800-5-1, one ormore of the following conditions for the associated protective circuit shall be satisfied:b) The protective conductor shall have a cross-sectional area of at least 10 mm2 Cu or 16mm2 Al, through its total run.c) Where the protective conductor has a cross-sectional area of less than 10 mm2 Cu or16 mm2 Al, a second protective conductor of at least the same cross-sectional areashall be provided up to a point where the protective conductor has a cross-sectionalarea not less than 10 mm2 Cu or 16 mm2 Al.d) Automatic disconnection of the supply in case of loss of continuity of the protectiveconductor.The cross-sectional area of every protective earthing conductor which does not form part ofthe supply cable or cable enclosure shall, in any case, be not less than:- 2.5mm2 if mechanical protection is provided or- 4mm2 if mechanical protection is not provided.The earth fault protection inside the AC drive protects only the drive itself against earth faultsin 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 switchesmay not function properly.CAUTION!Do not perform any voltage withstand tests on any part of the AC drive. There isa certain procedure according to which the tests shall be performed. Ignoring thisprocedure may result in damaged product.13006.emf13006.emf
