INSULATION RESISTANCE MEASUREMENT PROCEDURE FOR HYBRID
MOTOR [ROTATION MACHINE]
EN01H03ZZZ030602004005
! CAUTION
• Make it sure to wear insulation glove during inspection for safety.
• Pay attention to risk of electric shock during measurement.
1.
MEASURE INSULATION RESISTANCE BETWEEN "U PHASE - ROTOR TEMPERATURE SENSOR BRACKET
FIXING BOLT", "V PHASE - ROTOR TEMPERATURE SENSOR BRACKET FIXING BOLT" AND "W PHASE -
ROTOR TEMPERATURE SENSOR BRACKET FIXING BOLT" USING INSULATION RESISTOR. (REFER TO FIG-
URE 1)
! CAUTION
• Inspect in the state that engine and hybrid motor (rotor) are completely assembled.
• Never measure between each phase (U,V,W) terminal of three-phase of three-phase cable connector side. (Refer
to Figure 2)
