The Controller contains ESD-sensitive components. Use appropriate precautions in
connecting, disconnecting, and handling it.
Working on electrical systems is potentially dangerous; you should protect yourself against :
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.
Voltage hazard and high current arcs: batteries can supply high voltage and very high power,
and arcs can occur if they are short circuited. Always disconnect the battery circuit before
working on the motor control circuit.
Wear safety glasses and use properly insulated tools to prevent shorts.
Never energize the system if the terminals –B and +B are not tightly connected.
Lead acid batteries: charging or discharging generates hydrogen gas, which can build up and
go around the batteries. Follow the battery manufacturer’s safety recommendations and
wear safety glasses.
