ELECTRICAL SHOCK HAZARD - LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to connect the drive properly to protective earth (PE) can result in
death or serious injury.
Ensure reinforced protective earthing conductor according to IEC 60364-5-54 cl. 543.7 or according to
l
local safety regulations for high touch current equipment. The reinforced protective earthing of the drive
can be done with:
a PE conductor with a cross-section of at least 10 mm
l
an extra PE conductor of the same cross-sectional area as the original PE conductor as specified by IEC
l
60364-5-54 with a minimum cross-sectional area of 2.5 mm
(12 AWG) (not mechanically protected).
a PE conductor completely enclosed with an enclosure or otherwise protected throughout its length
l
against mechanical damage.
a PE conductor part of a multi-conductor power cable with a minimum PE conductor cross-section of 2.5

mm
power cable shall be installed with an appropriate strain relief).
NOTE: In IEC/EN 60364-5-54 cl. 543.7 and some application standards (for example IEC/EN 60204-1), the
l
limit for requiring reinforced protective earthing conductor is 10 mA leakage current.
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment can result in death or serious injury.
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.
l
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
Ensure that all safety covers are in place and securely fastened before applying power.
