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 recommendations.
Wear safety glasses.
WARNING
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.
These controllers contain ESD-sensitive components. Use appropriate precautions in connecting,
disconnecting, and handling the controller. See installation suggestions in Appendix A for protecting the
controller from ESD damage.
