- Sørg for, at alle forbindelser er sikre og korrekt polariserede for at forhindre beskadigelse af controlleren eller andre komponenter.
- Undgå at udsætte controlleren for vand, overdreven fugtighed eller ekstreme temperaturer.
- Forsøg ikke at åbne eller ændre controlleren casing, as this may void the warranty and pose a safety risk.
- Kontakt en kvalificeret tekniker, hvis du er usikker på nogen af installationstrinnene.
Opsætning og installation
Refer to the wiring diagram below for correct connection of the controller to your electric vehicle components. Ensure all connections match the specified colors and functions.

Detailed wiring diagram illustrating connections for battery, motor, throttle, key switch, brake switch, brake light, and indicator.
Ledningsforbindelser:
- Batteriforbindelse: Connect the battery wires to the corresponding terminals on the controller. Typically, red is positive (+) and black is negative (-).
- Motorforbindelse: Connect the motor wires (blue + and white -) to the motor output terminals.
- Throttle (Speed Governor): Connect the throttle unit. This typically uses a 1-4V signal for speed control.
- Nøglekontakt: Connect the key switch wires. Vigtig: The two wires of the key switch connector must be connected together (jumped) for the unit to power on and function.
- Bremsekontakt: Connect the brake switch wires. When activated, this switch cuts power to the motor.
- Bremselys: Connect the brake light wires (small red, small black) to the brake light connector.
- Indikator: Connect the indicator wires (small red, small black) for status display.
- Opladningsport: Connect the charging port if applicable.
Ensure all connectors are fully seated and secure. The controller features rubber grommets for wire protection and a rugged aluminum housing for durability and heat dissipation.

Betjeningsvejledning
Når controlleren er korrekt installeret, og alle forbindelser er sikre:
- Ensure the key switch is in the 'ON' position (or the wires are jumped as per installation).
- Tilfør strøm til systemet.
- Use the throttle (speed governor) to control the motor speed. The throttle typically operates within a 1-4V range.
- Engage the brake switch to cut power to the motor and activate the brake light.
Opretholdelse
- Hold controlleren ren og fri for støv og snavs.
- Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og tegn på slid eller korrosion.
- Ensure the controller's aluminum housing is not obstructed to allow for proper heat dissipation.
- Undgå at bruge skrappe kemikalier eller slibende materialer til rengøring.
Fejlfinding
