ELECTRICAL SHOCK HAZARD
The control terminals can have a dangerous voltage even when the drive is disconnected from mains. Contact
with this voltage can lead to injury.
Ensure that there is no voltage in the control terminals before touching the control terminals.
l
ACCIDENTAL MOTOR START
When there is a power-up, a power break, or fault reset, the motor starts immediately if the signal is active, unless the pulse
control for Start/Stop logic is selected. If parameters, applications or the software change, the I/O functions (including the start
inputs) can change. Activating the auto reset function, the motor starts automatically after an automatic fault reset. For more
information, see the Application Guide. Failure to ensure that the motor, system, and any attached equipment are ready for start
can result in personal injury or damage of the equipment.
Disconnect the motor from the drive if an accidental start can be dangerous. Ensure that the equipment is safe to operate
l
under any condition.
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
l
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.
DAMAGE TO THE AC DRIVE FROM INCORRECT SPARE PARTS
Using spare parts that are not from the manufacturer can damage the drive.
Only use original spare parts supplied by Danfoss.
