1 Open the compressor insulation.
2 Measure the voltage on the inverter on the smoothing capacitor
C4. Wait until the voltage drops below 10 V DC.
WARNING
The smoothing capacitor MUST discharge below 10 V DC
before disconnecting the Faston connectors from the
compressor wiring terminals. Risk of electrocution.
3 Disconnect the Faston connectors from the compressor wire
terminals U, V and W.
INFORMATION
Note the position of the Faston connectors on the
