NOTE • Before measurement, check that the smoothing capacitor is discharged. • At the time of electric discontinuity, the measured value is almost ∞. When there is an instantaneous electric continuity, due to the smoothing capacitor, the tester may not indicate ∞.
  • Page 170 NOTE • For parts replacement, contact the nearest Mitsubishi FA center.  Replacement procedure of the cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the cooling fan must be replaced immediately.
