Connecting to the Batteries and Motors

Connection to the batteries and motors is shown in the figure below and is done by con-

necting to the controller’s terminal strip.

1- Connect two of the three Ground terminals to the minus (-) terminal of the battery that

will be used to power the motors. Connectto the plus (+) terminal of the battery. The motor

battery may be of 12 to 40 Volts. There is no need to insert a switch on Motor Power

cables, although one is suggested.

The two VMot terminals are connected to each other inside the controller. The same

is true for the Terminals. You should wire each pair together as shown in the diagram

above.

2- You may leave the Power control terminal unconnected, or you may connect it to a

power switch.

Refer to the chapter “Connecting Power and Motors to the Controller” on page 21 for

more information about batteries and other connection options.

3- Connect each motor to one of the two output terminal pairs. Make sure to respect the

polarity, otherwise the motor(s) may spin in the opposite direction than expected

Notes:

- The Battery Power connection are doubled in order to provide the maximum current to the controller. If

only one motor is used, only one set of motor power cables needs to be connected.

- Typically, 1, 2 or 3 x 12V batteries are connected in series to reach 12, 24 or 36V respectively.

- The Power Control wire may be used to turn On and Off the controller, or to provide a separate and sta-

ble supply to the controller’s logic (See discussion below).
