Table 10: Connector for Main Power
Power to the Gold Whistle is provided by a 12 to 195 VDC source.
Connect the DC power cable to the VP+ and PR terminals on the Main Power Connector.
Notes for connecting the DC power supply
•
The source of the 12 to 195 VDC power supply must be isolated.
•
For best immunity, it is highly recommended to use twisted and shielded cables for the DC
power supply. 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.
•
Before applying power, first verify the polarity of the connection.
