5 - 3 5.3 Ground Resistance Test with a Megger When testing an external circuit with a megger, disconnect all the external circuit cables from the inverter to prevent it from being exposed to the test voltage. Use a tester (in high-resistance range mode) for a conduction test on the control circuit....

5 - 4 5.5 Method of Checking the Inverter and Converter Circuits You can check the quality of the inv erter and conv erter circuits by using a tester. (Preparation) 1) Remov e the external power supply cables from terminals R, T, and T, the motor cables from terminals U, V, and W, and the regenerati...

5 - 5 5.6 Replacing Parts The inverter consists of many parts and it functions normally only when all the parts operate normally. The table below lists the parts that may be subject to changes in characteristics and malfunctions after long-time use, even normally, over a specified number of years. E...

5 - 8 (3) Smoothing capacitors (on PCB) Smoothing capacitors on PCB is recommended to be replaced after 10 years of usage under standard installation, which is the same as main Smoothing capacitors. If abnormality is found by visual inspection and/or if the control power supply is not activated afte...
