disassemble the inverter to prevent an electric shock.
Perform discharging by connecting the discharging
resistance or plug of soldering iron to + , – terminals
of the C10 too 13 electrolytic capacitor (760μF) of
P.C. board.
Never use a screwdriver or similar device to di-
scharge the electrolytic capacitor components as a
electric shock may occur.
Under system fault condition, the electrolytic capa-
citor components may not have discharged. Ensure
these are discharged before proceeding.
2. Remove the inverter cover to gain access to

main body and the inverter box.
4. Remove various lead wires from the holder at
upper part of the inverter box and wiring holder at
right side of the terminal block.
5. Remove the lead wire from the bundled part at left
side of the terminal block.
6. Pull the inverter box upward.
7. Disconnect connectors of various lead wires.
REQUIREMENT
As each connector has a lock mechanism, avoid to
remove the connector by holding the lead wire, but
by holding the connector.

Caution: When mounting a new board, check that
the board is correctly set in the groove of the base
