1) Disconnect all power cables (R,S,T) and motor output cables (U,V,W).
2) Before testing, check the discharge of electrolytic capacitor (DCP-DCN).
3) When the circuit is open, DMM will indicate high resistance (several MΩ). In some situations, the DMM
may display a closed circuit (low resistance) and then show high resistance due to the capacitors.
When the circuit is closed, the DMM shows resistance of several hundred kΩ or less.
4) Displayed values may not be constant as it depends on the module and tester type. The value
measured between the phases is acceptable if the standard deviation is approximately ±10%.
