The controller can be oriented in any position as clean and dry as possible, or shield 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. Applying silicon gel or other thermal conductive material to contact
surface will enhance thermal performance.
Sufficient heat sink and air flow is required for high power application.
The case outline and mounting holes’ dimensions are shown in Figure 1.

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.
