2 — INSTALLATION & WIRING: Controller
programmer into its connector, and (2) that the built-in Status LED is visible
only through the view port in the label on top of the controller.
To ensure full rated power, the controller should be fastened to a clean,
at metal surface with four 6 mm (1/4") diameter screws, using the holes pro-
vided. Although not usually necessary, a thermal joint compound can be used to
improve heat conduction from the controller heatsink to the mounting surface.
Working on electric vehicles is potentially dangerous. You should pro-
tect yourself against runaways, high current arcs, and outgassing from lead
acid batteries:
RUNAWAYS — Some conditions could cause the vehicle to run out of control.
Disconnect the motor or jack up the vehicle and get the drive wheels o
the ground before attempting any work on the motor control circuitry.
: If the wrong throttle type is selected with the programming device,
the vehicle may suddenly begin to move.
HIGH CURRENT ARCS — Electric vehicle batteries can supply very high power,
and arcs can occur if they are short circuited. Always open the battery
circuit before working on the motor control circuit. Wear safety glasses,
and use properly insulated tools to prevent shorts.
LEAD ACID BATTERIES — Charging or discharging generates hydrogen gas,
which can build up in and around the batteries. Follow the battery man-
ufacturer’s safety recommendations. Wear safety glasses.
