(1) Cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit
semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration is noticed
during inspection, the cooling fan must be replaced immediately.
CAUTION
For parts replacement, consult the nearest Mitsubishi FA Center.

• Removal
1) Remove a fan cover.
2) After removing a fan connector, remove a fan block.
3) Remove the fan.
• Reinstallation
1) After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of "AIR FLOW" faces up.
2) Install fans referring to the above figure.
CAUTION
Installing the fan in the opposite air flow direction can cause the inverter life to be shorter.
Prevent the cable from being caught when installing a fan.
Switch the power off before replacing fans. Since the inverter circuits are charged with voltage even after power off,
replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.
