Connecting to the Batteries and Motors
Connecting to the Batteries and Motors
Connection to the batteries and motors is shown in the figure below and is done by con-
necting wires to the Fast-on tabs on the controller.
1- Connect two of the three Ground tabsto the minus (-) terminal of the battery that will be
used to power the motors. Connect the two VMot tabsto the plus (+) terminal of the bat-
tery. 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 tabs are connected to each other inside the controller. The same is
true for the Ground tabs. You should wire each pair together as shown in the dia-
gram above.
2- You may leave the Power control tab unconnected, or you may connect it to a power
switch.
Refer to the chapter “Connecting Power and Motors to the Controller” on page 25 for
more information about batteries and other connection options.
3- Connect each motor to one of the two output tabs pair. Make sure to respect the polar-
ity, 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)
