Instead of using a speed adjust potentiometer, the drive may be wired to follow a 0 - 5 VDC

signal (Figure 10). Connect the signal input (+) to S2. Connect the signal common (-) to S1. Make no

connection to S3. A potentiometer can be used as a voltage divider to scale the analog input voltage.

The analog signal common must be the same common as the battery common connected to BAT-. It

is acceptable to connect the negative side of the battery to Earth ground in some applications.
