Warning and Caution
Safety Information
This is not an all-inclusive list. Use common sense and act responsibly, electric motor controllers and
motors are extremely powerful and could cause death, dismemberment or other serious injury if misused
or not safely handled!
Wear protective or safety equipment such as safety shoes, safety glasses and gloves when working with
motors and controllers.
Remove all metal jewelry and metal objects from hands, wrist, fingers, etc. before working on any
electric motor or controller.
Insulate any tools that are used in proximity to connection points that have any voltage potential to
prevent shorts if the tool is accidentally dropped onto the terminals/connections.
Use caution when operating any controller or motor. If you're not sure what you're doing, or do not feel
comfortable with the situation, find a knowledgeable person to advise you.
Make certain the motor and controller are disconnected from any power source before servicing. If any
doubt exists of the voltage that might exist, measure with proper metering devices that are in good
functional condition, and rated for the voltages that could exist.
Verify and re-verify proper wiring connections.
Take extreme caution around series-connected batteries to avoid placing hands across live connections. It
is generally good practice to avoid the use of both hands when working around high voltage circuits. This
reduces the risk of an accidental short across the chest cavity.
If working on an electric vehicle, make certain the vehicle is positioned securely with the drive wheels
safely clear of the floor and blocked up so that the drive wheels cannot make contact with the floor under
any circumstances. Block the non-drive wheels if they remain in contact with the floor so that the vehicle
cannot roll in either direction.
Motors and controllers must only be connected to a power source by knowledgeable and experienced
personnel.
