2. ELECTRICAL CONNECTIONS
The electrical connections for the motor include the phase lead connections to the controller and the sensor cable lead connection to the controller. These wires and cables are housed in a protective conduit and should not beremoved from this covering. This harness should be properly strain relieved at all times, be sure to note the range of motion required between the controller and the motor due to suspension travel of the vehicle. The following sections give instructions for these connections. 2.1 Phase Lead Connections The phase leads are permanently attached at the motor end. Any attempt to remove or modify theconnections at the motor end may void the warranty. The phase leads have not been terminated to allow the user to customize the cable length and method of connection to the EV-C200-XX2 series controller. It is recommended that no less than 6AWG be utilized in the connections of the phase leads to the controller and that any connectors used be sufficiently rated to handle the current and voltage.
