MOUNT THROUGH A 0.38 IN. (10 MM) HOLE
Figure 3. Speed Adjust Potentiometer
If using a remote potentiometer with a chassis drive, mount the speed
adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware
provided (Figure 3). 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 the speed adjust potentiometer wires are longer than
18 in. (46 cm), use shielded cable. Keep the speed adjust potentiometer
wires separate from power leads (L1, L2, A1, A2, F1, F2).

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