WARNING!
If the cable connection between the drive and the motor has an in-line contactor or
circuit breaker then the drive must be stopped prior to opening/closing the contacts.
Failure to do so may result in 0vercurrent trips and/or damage to the inverter.
WARNING!
Leakage current may exceed 3.5 mA AC. The minimum size of the protective
earth (PE) conductor shall comply with local safety regulations for high leakage
current equipment.
STOP!
In the case of a Spinning Motor:
To bring free-wheeling loads such as fans to a rest before starting the drive, use the DC injection
braking function. Starting a drive into a freewheeling motor creates a direct short-circuit and may
result in damage to the drive.
Confirm motor suitability for use with DC injection braking.
Consult parameter P110 for starting / restarting into spinning motors.
