  • Page 61: 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 62 Especially for a completely electromagnetic MCCB, a slightly large capacity must be selected since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.) As an earth leakage current breaker, use the Mitsubishi Electric earth leakage current breaker designed for harmonics and surge suppression.
  • Page 63 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 64 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 65 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.

  • Page 66: Power Supply Harmonics

    Power supply harmonics Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
  • Page 67 Power supply harmonics 3.2.2 Harmonic suppression guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. 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"...

  • Page 74: Failsafe System Which Uses The Inverter

    Although Mitsubishi Electric assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
