 WARNING
ELECTRICAL SHOCK HAZARD - LEAKAGE CURRENT HAZARD >3.5 MA
Leakage currents exceed 3.5 mA. Failure to connect the drive properly to protective earth (PE) can result in
death or serious injury.
l Ensure reinforced protective earthing conductor according to IEC 60364-5-54 cl. 543.7 or according to
local safety regulations for high touch current equipment. The reinforced protective earthing of the drive
can be done with:
l a PE conductor with a cross-section of at least 10 mm
2
(8 AWG) Cu or 16 mm
2
(6 AWG) Al.
l an extra PE conductor of the same cross-sectional area as the original PE conductor as specified by IEC
60364-5-54 with a minimum cross-sectional area of 2.5 mm
2
(14 AWG) (mechanically protected) or 4 mm
2
(12 AWG) (not mechanically protected).
l a PE conductor completely enclosed with an enclosure or otherwise protected throughout its length
against mechanical damage.
l a PE conductor part of a multi-conductor power cable with a minimum PE conductor cross-section of 2.5
mm
2
(14 AWG) (permanently connected or pluggable by an industrial connector. The multi-conductor
power cable shall be installed with an appropriate strain relief).
l NOTE: In IEC/EN 60364-5-54 cl. 543.7 and some application standards (for example IEC/EN 60204-1), the
limit for requiring reinforced protective earthing conductor is 10 mA leakage current.
 WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment can result in death or serious injury.
l Ensure that only trained and qualified personnel perform installation, start-up, and maintenance.
l Ensure that electrical work conforms to national and local electrical codes.
l Follow the procedures in this guide.
 CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
l Ensure that all safety covers are in place and securely fastened before applying power.
