LEESON FHP Series Chassis Mount Variable Speed Drives - Manual (Page 31)

21 Installation
Mount the speed adjust potentiometer through a 0.38 in.
(10 mm) hole with the hardware provided (Figure 11). 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, U,
V, W).
