4 Dos and Don'ts
Do
Set up the gain, accel and decel presets to suit your battery voltage and requirements. Page 6.
Keep the controller covered at all times- or water, dust and dirt will enter.
Fit reverse polarity protection - this is also an emergency power disconnect so is necessary for safety.
Make sure terminal nuts are tight - current through a loose connection will burn it.
Keep the motor in good condition. Damaged brushgear and commutators can blow the controller.
Fit a motor suppression capacitor. A 10n ceramic across the motor brushes, as close to the motor as
possible, can greatly increase system reliability.
Do not
Drill or otherwise modify the metal base - it's impossible to keep metal swarf out of the controller. This
WILL blow the controller!
Test the controller without securing the top board in place: as a bare minimum, loosely insert the two
screws at the end away from the 6 way connector.
Connect the batteries with the ignition on. the ignition is also a reset switch if the controller trips for any
reason!
Make any soldered connection to the board. Such modification invalidates the guarantee!
