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 76).
9. Run the compressor and measure the current in each phase; the current for each phase should be identical (refer to "Product
