Connecting the Main Power Cable
Connect the main power supply cable to the VP+ and PR terminals of the main power
connector. Connect the Protective Earth wire to the PE terminal on the Falcon’s heatsink.
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 both ends of the cable shield to the closest ground connection, one end near the
power supply and the other end to the PE terminal on the Falcon’s heatsink.
•
For safety reasons connect the PR of the power supply to the closest ground connection.
