Requires Heavy-Duty Switch or Power Contactor: This controller does not have a built in power relay to turn it on and off. A heavy-duty power disconnect switch such as item # SWT-700 or power relay such as item # RLY-24150 is needed to turn this controller on and off.

Under Voltage Battery Protection: When the battery pack falls below a specific Voltage the controller turns the motor off preventing over discharging of the battery pack which extends the battery packs lifespan. (The cutoff value is approximately 20.5 Volts ± 1.0 Volts)
Motor Cut-Off During Braking: When the brakes are engaged the brake switch signals the controller to turn off the motor. The motor turns on again after the brakes are released.

~Optional Connection
*The battery pack should be the last connection made.
*A power switch, power contactor, or power relay and fuse or circuit breaker protection needs to be installed between the speed controller and the battery pack.
*The two red wires going to the battery and motor are connected together inside of the controller so it does not matter which one goes to the battery or motor.

~Optional connections do not need to be connected to anything in order for the controller to operate.
