Maintenance

Replacing the internal cooling fans

WARNING! 

Obey the safety instructions on page 

5

. If you ignore the 

instructions, physical injury or death, or damage to the equipment can 

occur.

1. Before you start, stop the inverter and 

do the steps in 

Electrical safety

 on page 

6

.

2. Open the cabinet doors and remove the 

touch protection shrouds.

3. Disconnect the power and control 

cables of the cooling fans.

4. Loosen the screws that attach the 

cooling fan holder.

5. Remove the cooling fan holder.

6. Remove the screws that attach the 

cooling fan to the cooling fan holder.

7. Replace the cooling fan. Make sure that 

the air flow direction is correct.

8. Install and tighten the 4 screws to attach 

the cooling fan to the cooling fan holder.

9. Connect the power and control cables 

of the cooling fans.

10. Install the touch protection shrouds and 

close the cabinet doors.

11. After the inverter starts, make sure that 

there are no fan failure warnings. You 

can read the status of each fan from 

parameter group 202
