Chapter 9 LIST OF PERIPHERAL EQUIPMENT AND OPTIONS
The table below lists the main peripheral equipment and options that are connected to the FRENIC-Lift. Use them
in accordance with your system requirements.

protection
MCCBs are designed to protect the power circuits between the power control board and
inverter’s main terminals (L1/R, L2/S and L3/T) from overload or short-circuit which in turn
prevents secondary disasters caused by the inverter malfunctioning.
RCDs/ELCBs function in the same way as MCCBs. Use the MCCBs and RCDs/ELCBs that
satisfy the recommended rated current listed below.

Note: A box () in the above table replaces C (China), E (EU), A (Asia) or J (Japan)
depending on the shipping destination.
Select the MCCB or RCD/ELCB with appropriate breaking capacity according to the power
supply capacity.
When connecting the inverter to the power supply, add a recommended molded case
circuit breaker and earth leakage circuit breaker* in the path of power supply. Do not use
the devices with the rated current out of the recommenced range.
*With overcurrent protection
Fire could occur.
