H. Inspection. After wiring is complete, verify that all wiring is correctly installed,
excess screws and wire clippings are removed from inside of unit, screws are
securely tightened, and exposed wire does not contact other wiring or terminals.
If a FWD or REV run command is given from the control
circuit terminal when the operation method selection
function ( n003 ) is set to " 1 " and the "LO/RE" selection
is set to "RE", the motor will start automatically as soon
as power is applied to the main circuit.
