The diagram shows a typical wiring diagram for a Pro-120 controller (Pro-120 specification). Wiring of the VTX (VTX specification) (and the earlier NCC series) is identical. The new Pro-150 (Pro-150 specification) is also interchangeable in most situations.
An alternative page is available showing the wiring with two push buttons (forward and reverse).
A separate page shows the wiring for two VTX or NCC series with a Dual Channel Interface (DCI-111)which replaces all but the battery and motor wiring.
All you need are motor wires, battery wires, an ignition switch, a forward reverse switch and a potentiometer to tell the controller what speed you require.
The 6 way connector is supplied and is connected simply by inserting the wires (which must be the correct size: 7/0.2mm² wire which is commonly available or we can supply as either multicore or ribbon cable.
Of course there are many options available: we show a toggle switch for ignition and reverse but you will probably want a keyswitch for ignition. We have a selection of switches for the reverse switch also. For the pot, you may require something more sophisticated than a rotary pot: we have a finger-tip throttle mechanism and a plunger pot suitable for use with a foot pedal.
Battery condition meter is, of course, optional.
All these bits are illustrated in our accessories catalogue from where you can order them.
Two fuses are shown: the one in the battery wire is not generally required with the Pro series except to protect against major faults in the wiring. However, with the VTX or NCC series, it will give a good measure of reverse polarity protection.
The 1A fuse shown in the yellow wire is optional: there is on on-board fuse track. However if you cannot cope with the fuse track then an external fuse is sensible. It only protects the controller against major faults in the control wiring.
You may prefer to fit a self-resetting fuse.
On the Pro controllers undervoltage cutback is a 'user option' which is enabled by fitting the resistor (shown bottom left) in the ignition wire.
