3.4.2.2 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 Cello’s heat sink.
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 Cello’s heat sink.
For safety reasons connect the PR of the power supply to the closest ground
connection.
