A barrier terminal strip inside the handle's case provides connections to power, ground, and
potentiometers when no external cable is ordered. Run a cable from the strip through the strain relief
provided on the side or bottom of the case. Reference
handle movement causes a current flow from terminal B to A when the terminal strip is facing you.

Warning
An unforeseen failure may cause an output which could activate a valve or pump. Unexpected vehicle or
mechanism movement can endanger people or damage equipment. Handles equipped with a center-off
switch will mitigate this condition. When an active neutral is necessary, provide an operator-presence
interlock and/or braking system sufficient to stop and hold the system or vehicle.
In most applications, auxiliary switches must be customer-wired, as shown in
page 14. When the switch is used as a center-off, power is connected from the external 12 Volt supply
to the terminal labeled common. The switch terminals are 3/16 inch quick-connect.
(primarily) on page 15 shows a pre-wired control handle with center-off switch and Delphi connector,
exhibiting the handle phasing and color coding of the wires.
The following illustration shows how to assemble the mating Delphi connector (male shell, female
sockets) used in PWM Option (primarily)

PWM MCHXXX option models are fitted with trim potentiometers for adjusting the output current. The
following illustration shows the location of the three trim potentiometers on the L handle. There are
either 3 or 4 trim potentiometers depending on the specific MCHXXX model. Reference
