[Note in case of the EZJ127 board replacement]
- When replacing the board, be sure to turn off the power.
- Before replacing the board, be sure not to supply the electric power to the wires
connecting to TB1.
- Perform the setting of SW1 and 2.
-There are two type of EZJ127 board. (EZJ127A and EZJ127B)
- When replacing the board, first remove the harness from the board by removing
the fixing screws, Then, pulling the board upward and securing enough space to work,
disconnect the harness.
