WARNING
ACCIDENTAL MOTOR START
When there is a power-up, a power break, or a fault reset, the motor starts immediately if the start signal is active, unless the
pulse control for Start/Stop logic is selected. If the parameters, the applications or the software change, the I/O functions
(including the start inputs) can change. If you activate the auto reset function, the motor starts automatically after an automatic
fault reset. 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 equipment damage.
-
Disconnect the motor from the drive if an accidental start can be dangerous. Make sure that the equipment is safe to
operate under any condition.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
-
Ensure the correct grounding of the equipment by a certified electrical installer.
WARNING
SHOCK HAZARD FROM PE CONDUCTOR
The drive can cause a DC current in the PE conductor. Failure to use a residual current-operated protective (RCD) device Type B
or a residual current-operated monitoring (RCM) device can lead to the RCD not providing the intended protection and
therefore can result in death or serious injury.
-
Use a type B RCD or RCM device on the mains side of the drive.
