NOTE
• Installing the fan in the opposite direction of air flow may shorten the inverter life.
• Ensure that the cables are not caught when the fan is installed.
• Switch OFF the power before starting the fan replacement work. To prevent an electric shock accident, keep the inverter with
its covers on during fans replacement since the inverter circuits are charged with voltage even after power OFF.
