    EMC and leakage currents 3.1 EMC 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 64 22(1)* Phase grounding Earthed-neutral system *For the FR-A720-0.4K and 0.75K, the EMC filter is always valid. The leakage current is 1mA. CAUTION ⋅ Install the earth leakage breaker (ELB) on the input side of the inverter. ⋅ In the connection earthed-neutral system, the sensitivity current is blunt against an earth (ground) fault in the inverter output side.

    EMC and leakage currents 3.1.2 EMC measures Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
  • Page 66 EMC and leakage currents Noise Propagation Measures Path When devices that handle low-level signals and are liable to malfunction due to electromagnetic 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 electromagnetic noises.
