  • Page 77: Electro-Magnetic Interference (Emi) And Leakage Currents

    Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) and leakage currents 3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
  • Page 78 (Check it in the data of the corresponding breaker.) As an earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge suppression. Selecting the rated sensitivity current for the earth leakage circuit breaker When using an earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency.
  • Page 79 Electro-magnetic interference (EMI) and leakage currents NOTE • Install the earth leakage circuit breaker (ELB) on the input side of the inverter. • In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
  • Page 80 Electro-magnetic interference (EMI) and leakage currents Noise propagation Countermeasure path When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are near the inverter or when the signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.
  • Page 81 Electro-magnetic interference (EMI) and leakage currents 3.1.3 Built-in EMC filter This inverter is equipped with a built-in EMC filter (capacitive filter) and a common mode choke. These filters are effective in reducing air-propagated noise on the input side of the inverter. To enable the EMC filter, fit the EMC filter ON/OFF connector to the ON position.

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products"...
