3.3 Motor Power Cable

Prepare the motor power cable, which has four wires: U, V, W and E (earth ground). Proper size and length of cable

should be used.

4. Hardware Installation

4.1 Safety Precautions

ATTENTION: Remove and lock out power from the drive before you disconnect or reconnect

wires or perform service. Wait three minutes after removing power to discharge the bus voltage.

Do not attempt to service the drive until bus voltage has discharged to zero. Failure to do so may

result in bodily injury or death.

!

ATTENTION: The drive is intended to be commanded by control input that will start and stop

the motor. A device that routinely disconnects then reapplies input power to the drive for the

purpose of starting and stopping the motor should not be used. Failure to follow this guideline

may result in damage of equipment, and/or bodily injury or death.

!

ATTENTION: Do not connect power factor correction capacitors to drive output terminals U,

V, and W. Failure to do so may result in equipment damage or bodily injury.
