INSTALLATION AND WIRING 2.3.2 Harmonic suppression guidelines Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guidelines were established to protect other consumers from these outgoing harmonic currents. 1) "Harmonic suppression guideline for household appliances and general-purpose products" This guideline was issued by Ministry of Economy, Trade and Industry (formerly the Ministry of International Trade and Industry) in September, 1994 and applies to 200V class inverters of 3.7kW or less.

Page 47: Inverter-Generated Noises And Their Reduction Techniques
INSTALLATION AND WIRING 2.3.3 Inverter-generated noises and their reduction techniques Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following basic measures to be taken.
Page 48 INSTALLATION AND WIRING Noise Path Measures When devices that handle low-level signals and are liable to malfunction due to noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated noises.
Page 49 INSTALLATION AND WIRING • Data line filter Noise entry can be prevented by providing a data line filter for the detector cable etc. • Data examples By decreasing the carrier frequency, the noise terminal voltage* can be reduced. Use Pr. 72 to set the carrier frequency to a low value (1kHz).
Page 50: Leakage Currents And Countermeasures
INSTALLATION AND WIRING 2.3.4 Leakage currents and countermeasures Leakage currents flow through static capacitances existing in the inverter I/O wiring and motor. Since their values depend on the static capacitances, 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 line through the earth (ground) cable, etc.
Page 51: Inverter-Driven 400V Class Motor
INSTALLATION AND WIRING 2.3.5 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures.
