Mount the speed adjust potentiometer through a 0.38 in. (10 mm)

hole with the hardware provided (Figure 5). Install the circular

insulating disk between the panel and the 10K ohm speed adjust

potentiometer. 

Twist the speed adjust potentiometer wire to avoid picking up

unwanted electrical noise. If speed adjust potentiometer wires are

longer than 18 in. (457 mm), use shielded cable. Keep speed

adjust potentiometer wires separate from power leads (L1, L2, A1,

A2).

Warning

Be sure that the potentiometer tabs do not make contact with
the potentiometer enclosure. Grounding the input will cause
damage to the drive.
