Chapter 6 Maintenance and Inspection Increase the voltage to 90% and keep for 1 hour. Then apply rated voltage for 5 hours. *5 In case fan is locked by dust or particle, it takes 5 to 10 seconds to restart even after the dust is removed. 6.3 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.

Chapter 6 Maintenance and Inspection 6.5 Method of Checking the Inverter and Converter Circuits You can check the quality of the inverter and converter circuits by using a tester. (Preparation) 1) Remove the external power supply cables from terminals R, T, and T, the motor cables from terminals U, V, and W, and the regenerative braking resistor cables from terminals P and RB.
