Caution:
Power from the Gold DC Whistle to the motor must come from the Main Supply
and not from the Auxiliary Supply.
The backup functionality can be used for storing control parameters in case of power-outs,
providing maximum flexibility and backup capability when needed.

To connect the auxiliary supply:
1.

closest ground near the auxiliary supply source
