2 — INSTALLATION & WIRING
Working on electrical systems is potentially dangerous. 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 manufacturer’s safety recom-
mendations. Wear safety glasses.

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 1222 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.
