2. DC SOURCE OPTIONAL
Connect the DC power supply cable to the VP+ and PR terminals of the main power connector.
Notes for connecting the DC power supply:
 The source of the 0 ~ 88 VDC Power Supply must be isolated.
 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.
 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.

.11.3 Low power Auxiliary Supply (optional)
Notes for 12 ~ 95 VDC Auxiliary Supply connections:
 The source of the 12 ~ 95 VDC Auxiliary Supply must be isolated from the main.
 For safety reasons, connect the return (common) of the Auxiliary Supply source to the
closest ground near the Auxiliary Supply source.
 Connect the cable shield to the closest ground near the Auxiliary Supply source.
 Before applying power, first verify the polarity of the connection.

Caution: Power to each Whistle and motor must come from the Main Supply
and NOT from the Auxiliary Supply.
