Note Determining Wire Size
Determine the wire size for the main circuit so that line voltage drop is within 2% of the
rated voltage.
Line voltage drop is calculated as follows:
Line voltage drop (V) = √3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10 –3
Wiring on the Input Side of Main Circuit
Installing a Molded-case Circuit Breaker
Always connect the power input terminals (L1, L2, and L3) and power
supply via a molded-case circuit breaker (MCCB).
• Choose an MCCB with a capacity of 1.5 to 2 times the Inverter’s rated
current.
• For the MCCB’s time characteristics, be sure to consider the Inverter’s
overload protection (one minute at 150% of the rated output current).
