CONTROLLER WIRING: BASIC CONFIGURATION
A basic wiring diagram is shown in Figure 3. rottle and brake are shown in the diagram as 3-wire
potentiometers; other types of throttle and brake inputs are easily accommodated, and are discussed
in the following throttle wiring section.
e main contactor coil must be wired directly to the controller as shown in Figure 3 to meet EEC
safety requirements. e controller can be programmed to check for welded or missing contactor
faults and uses the main contactor coil driver output to remove power from the controller and motor
