Warning
Be sure that the potentiometer tabs do not make contact with
the potentiometer enclosure. Grounding the input will cause
damage to the drive.
Mount the speed adjust potentiometer through a 0.38 in. (10 mm)
hole with the hardware provided (see Figure 5 on Page 10). 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).
