2 — INSTALLATION & WIRING: Controller
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. NOTE: If the wrong throttle input signal type is selected
with the 13XX programmer, the vehicle may suddenly begin to move.
HIGH CURRENT ARCS — 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
manufacturer’s safety recommendations. Wear safety glasses
.
holes provided. Although not usually necessary, a thermal joint compound
can be used to improve heat conduction from the controller heatsink to the
mounting surface.
You will need to take steps during the design and development of your
end product to ensure that its EMC performance complies with applicable
regulations; suggestions are presented in Appendix A.
The 1230 controller contains ESD-sensitive components. Use appro-
priate precautions in connecting, disconnecting, and handling the controller.
See installation suggestions in Appendix A for protecting the controller from
ESD damage.
