[Note for EZJ127 board replacement]
- When replacing the board, be sure to turn the main power switch OFF.
- Be sure NOT to supply the electric power to the wires connected to TB1.
- Perform the setting of SW1 and 2.
-There are two types of EZJ127 board. (EZJ127 A board and EZJ127 B board)
- When you remove the harnesses from the board, remove fixing screws of the board first.
And then remove harnesses with pulling the board from inside of the unit.
