Wait at least 10 minutes, the maintenance work can only be carried out after the capacitor inside the inverter has been discharged. z

Only professional electricians can perform fan maintenance and replacement work.

The fan replacement steps are as follows:

(1) Disconnect AC circuit breaker.

(2) Turn the DC switch to the "OFF" position.

(3) Wait at least 10 minutes.

(4) Disconnect all electrical connections from the bottom of the inverter.

34


Operation

(5) Lift the inverter with the help of others and remove the inverter from the wall.

(6) Place the inverter on the operating platform.

(7) Disassemble the fan case as shown in Figure 5.2.

(8) As shown in Figure 5.3, remove the damaged inverter fan, install the good fan to the original position, and connect the fan power supply and control cable.
