Removal and Installation
Follow these steps to measure the resistance between the main fan supply wires
and remove and replace the main fan, if necessary.

• To identify which fan is installed in your drive, see Fan Inverter System

• For AC fan systems, the sheet metal bracket is available as a spare part (SK-
H1-FR9BRKT). See page
288 for details. For DC fan systems, the sheet
metal bracket is only available as part of the retrofit kit (SK-H1-
DCFANRETROFIT-F9). See page

• The main fan replacement kit only contains the fan motor and impeller
assembly. Therefore, if the sheet metal mounting bracket is not available as
a spare part for your fan system, it must be reused.
