Connecting the Main Power Cable

Connect the main power supply cable to the VP+ and PR terminals of the main power
connector.

Notes for connecting the DC power supply:

•

Be sure to isolate the source of the DC power supply.

•

For best immunity, it is highly recommended to use twisted cables for the DC power supply

cable. A 3-wire shielded cable should be used. The gauge is determined by the actual
current consumption of the motor.

•

Connect the cable shield to the closest ground connection near the power supply.

•

Connect the PE to the closest ground connection near the power supply.

•

Connect the PR to the closest ground connection near the power supply.
