Chapter3 Wiring and Installation
3.1 Mounting the Controller
The controller can be oriented in any position which should be as clean and dry as possible,
and if necessary, shielded with a cover to protect it from water and contaminants.
To ensure full rated output power, the controller should be fastened to a clean, flat metal
surface with four screws. A thermal joint compound can be used to improve heat conduction
from the case to the mounting surface. The case outline and mounting holes’ dimensions are
shown in Figure 1.
Caution:
• RUNAWAYS
—
Some conditions could cause the motor to run out of control.
Disconnect the motor, or jack up the vehicle, and get the drive wheels off the
ground before attempting any work on the motor control circuitry
.
• HIGH CURRENT ARCS
—
Electric vehicle batteries can supply very high power, and
arcs can occur if they are short circuit. Always turn off the battery circuit before
working on the motor control circuit. Wear safety glasses, and use properly
insulated tools to prevent short circuit
.
