ATTENTION: Disconnect the input power supply before installing or
servicing the motor. Motor lead connections can short and cause damage
or injury if not well secured and insulated. Insulate the connections, equal
to or better than the insulation on the supply conductors. Properly ground
the motor per the selected drive manual.
