NOTE
 Installing the fan in the opposite of air flow direction can cause the converter life to be shorter.
 Prevent the cable from being caught when installing a fan.
 Switch the power OFF before replacing fans. Since the converter circuits are charged with voltage even after power
OFF, replace fans only when the converter cover is on the converter to prevent an electric shock accident.
