2 — INSTALLATION & WIRING
Working on electrical systems is potentially dangerous. You should
protect yourself against uncontrolled operation, high current arcs, and
outgassing from lead acid batteries:
UNCONTROLLED OPERATION
— Some conditions could cause the motor to
run out of control. Disconnect the motor or jack up the vehicle and get
the drive wheels off the ground before attempting any work on the motor
control circuitry.
HIGH CURRENT ARCS
— Batteries can supply very high power, and arcing 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.
