3.8.2. Connecting Main Power
Connect the DC power supply cable to the VP+ and PR terminals of the Main power connector.
Notes for connecting the DC power supply
:
1. The source of the 0 to 95 VDC Power Supply must be isolated.
2. For the greatest immunity, it is highly recommended to use twisted and shielded 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.
3. Connect the cable shield to the closest ground connection near the power supply.
4. Connect the PE to the closest ground connection near the power supply.
5. Connect the PR to the closest ground connection near the power supply.
6. Before applying power, first verify the polarity of the connection.
