  • Page 87 2 Design  Installing earth leakage breaker When selecting the earth leakage breaker to use between the power supply and the main power supply input terminals (R/L1, S/L2, T/L3), consider the following two points. High-frequency leakage current from inverter The inverter produces a high-frequency leakage current due to its high-speed output switching. In general, a leakage current of approximately 100 mA will flow for the power cable length of 1 m per inverter.
  • Page 88 2 Design  Inrush current flow when the inverter power supply is turned ON When the inverter power supply is turned ON, the charging current, which is called inrush current, flows in the main circuit board capacitor. The table below shows the reference values at a power supply voltage of 240 V or 480 V when the power supply impedance is low.
  • Page 89 2 Design  Installing input surge absorber When using an inductive load (such as a magnetic contactor, magnetic relay, magnetic valve, solenoid, or electromagnetic brake), use a surge absorber or diode together.  Installing input noise filter The inverter performs high-speed output switching, which may cause the noise flow from the inverter to power supply lines that negatively affects on peripheral equipment.

    2 Design  DC/AC reactor To suppress harmonic currents, use the DC (direct current) and AC (alternating current) reactors. The DC/AC reactor functions to suppress a steep change in the current. The DC reactor has a higher harmonics suppression ability, so even higher suppression ability can be expected when used in conjunction with the AC reactor.

  • Page 94 2 Design  Measures against radio noise Besides the I/O wires, radio noise is radiated from the inverter itself. This radio noise can be reduced by installing noise filters on both the input and output sides of the inverter and by installing and shielding the inverter body in a grounded iron enclosure etc.
