caution | The insulation resistance check must be completed within 10 seconds. (Since DC 1,000 V is applied while checking, parts may be damaged if the check continues for 10 seconds or more.) |
Required Special Tools:
- MB991223: Wiring harness set
- MB992006: Extra fine probe
- MB992355: Electric insulation tester
4. Disconnect the high voltage cable (P, N) from the AC inverter.
5. Disconnect the AC power supply wiring harness from the AC inverter.
6. Use the electric insulation tester (Special tool: MB992355) and set it to the 1,000 V range.
7. Measure the insulation resistance between the AC inverter high voltage terminals (P, N) and AC power supply terminals (AC+, AC-), and AC inverter (body ground).Standard value: 10 MΩ or more
8. If the measured value is not within the standard value, replace the AC inverter.
