9. After cleaning, insert the fan plug into the pin
connector until it snaps into place.
10. Insert the fan into the inverter until it snaps into place.
11. Attach the ventilation grids on the right-hand and left-hand side of the inverter:
• Reinsert the ventilation grid until it snaps
into place.
• Turn the rotary lock of the ventilation grid
with a flat-blade screwdriver until the slot is
in a horizontal position and the arrows
point to the right.
• Ensure that the ventilation grid is securely in place.
12. Recommission the inverter (see Section 11, page 58).
13. Check the fans to ensure that they are working properly (see Section 10.4, page 54).
10.4 Checking the Function of the Fans
You can check the function of the fans by setting a parameter.
The basic procedure for changing operating parameters is described in the manual of the inverter
or the communication product (see the operating manual of the inverter or communication product).
Procedure:
1. Select the parameter
Fan test
or
FanTst
and set to
On.
2. Save settings.
3. Check whether air is being drawn in through the bottom and is coming out of the upper
ventilation grids and whether the fans are making any unusual noises.
If no air is being drawn in through the bottom, no air is coming out of the ventilation grids, or
the fans are making unusual noises, then the fans were presumably installed improperly.
Check whether the fans have been installed correctly.
If the fans were installed correctly, contact Service (see Section 17, page 74).
