7. Megger the compressor using 500 or 1000 VDC, the insulation must be higher than 3 MΩ.
8. Replace the compressor if the windings and/or insulation measurements fail (refer to "Replacing compressor" on page 84).
9. Run the compressor and measure the current in each phase; the current for each phase should be identical (refer to "Product
specific information" on page 118). In that case it can be decided to preventively replace the compressor (refer to "Replacing
