    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. The amount of current leakage depends on the size of the capacitance. Take the following precautions to prevent current leakage.

Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
  • Page 72 Electro-magnetic interference (EMI) and leakage currents 3.1.2 Countermeasures against inverter-generated Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
  • Page 73 Electro-magnetic interference (EMI) and leakage currents Noise Countermeasure propagation 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 the converter unit, or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.

These filters are effective in reducing air-propagated noise on the input side of the converter unit. To enable the EMC filter, connect two EMC filter ON/OFF female connectors to the ON male connectors.

    Failsafe system which uses the inverter Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function is activated 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.
