CAUTION
•
Installing the fan in the opposite of 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.
