    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 70 Electro-magnetic interference (EMI) and leakage currents Installation and selection of the molded case circuit breaker Install a molded case circuit breaker (MCCB) on the power receiving side to protect the wiring at the inverter input side. Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output frequency and load.
  • Page 71: Countermeasures Against Inverter-generated Emi

    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.

    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 74 Electro-magnetic interference (EMI) and leakage currents • Switching ON/OFF the filter (1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is OFF, wait for at least 10 minutes after the power supply has been switched OFF, and check that there is no residual voltage using a tester or the like.

  • Page 83: Failsafe System Which Uses The Inverter

    Failsafe system which uses the inverter Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function activates and outputs a fault signal. However, a fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi 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.
  • Page 84 • Changing the terminal assignment using Pr.190 and Pr.196 (output terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal. • For the details of the parameters and signals, refer to the FR-A800 Instruction Manual (Detailed). Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of the inverter itself.
