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.
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.
