INSTALLATION AND WIRING 2.3.3 EMC measures Some electromagnetic noises enter the inverter causing it to incorrectly operate, and others are radiated by the inverter causing misoperation of peripheral devices. Though the inverter is designed have high immunity performance, it handles low-level signals, so it requires the following basic measures to be taken. Also, since the inverter chops the output at high carrier frequencies, it could generate electromagnetic noise.
INSTALLATION AND WIRING 3) Techniques to reduce electromagnetic noises that are radiated by the inverter to malfunction peripheral devices (EMI measures) periperal devices Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuit (I/O), those electromagnetically and electrostatically inducted to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

INSTALLATION AND WIRING 2.3.4 Leakage currents and countermeasures Due to the static capacitance existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitance, carrier frequency, etc., take the following measures. (1) To-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other lines through the earth (ground) cable, etc.
INSTALLATION AND WIRING z Countermeasures • Use the electronic thermal relay function of the inverter. • Decrease the carrier frequency. Note that motor noise increases. Selection of SoftPWM will make it unoffending. To ensure that the motor is protected not to be influenced by line-to-line leakage currents, we recommend the protection method which uses a temperature sensor to directly detect motor temperature. 2.3.
