To protect the inverter, it is recommended to use semiconductor fuses like they are shown in the
table below.
Table 4 Input Fuse Selection
Consider the following precautions for the main circuit power supply input.
• If a moulded case circuit breaker is used for the power supply connection (R/L1, S/L2, and T/L3),
ensure that the circuit breaker is suitable for the Inverter.
