• Install the MCCB or RCD/ELCB at the input side of the inverter. They cannot be installed at the output side of the
inverter.
• The above table lists the rated current of MCCBs and RCD/ELCBs to be used in the power control panel with an
internal temperature of lower than 50°C. Select an MCCB and/or RCD/ELCB suitable for the actual short-circuit
breaking capacity needed for your power systems.
• When selecting an MC, the HIV wire (capable of 75°C) is assumed. If an MC type for another class of wires is
selected, the wire size suitable for the terminal size of both the inverter and the MC type should be taken into
account.
