Warning! Power must be turned off before wiring. Connect control in series with motor and line volt-
age; never connect control across line. Ground (Earth)** – Be sure to ground the control using the
green wire.
**Some models do not require grounding, therefore, a ground wire is not provided.

a) Use 2” deep standard electrical box.
b) Secure control with outer bracket tabs.
4. Minimum Speed Adjustment
Important: If this option is not supplied, disregard Step 4 and continue to Step 5. This control was de-
signed to operate on motors used in diverse applications. A minimum speed adjustment is provided
to allow independent control of the minimum speed setting. Minimum speed adjustment ensures
motor runs with suffi
cient torque to prevent stalling.
a) Motor must be in actual operating condition to achieve proper speed adjustment. Motor will
not slow down unless proper load is applied.
b) Turn main control knob to lowest speed position.
c) Locate and adjust minimum speed setting on front plate with screw driver (rotate clockwise to
decrease minimum speed; counter-clockwise to increase minimum speed).
Special Note:
For 2.5 and 3.0 Amp models, adjustment of minimum speed is reversed. Rotate
clockwise to increase minimum speed; counter-clockwise to decrease minimum speed.
On some models minimum speed adjustment hole is located on side of control.
d) Motor will now operate from this preset minimum speed to full speed.
