Design
Choose the sensitivity current of the earth leakage breaker (ELB), depending on the total distance (L) between
the Inverter and the power supply, and the Inverter and the motor.
îš„Terminal Arrangement
*1. For 3G3JX-AE, R/L1 corresponds to L1, S/L2 to L2, and T/L3 to N/L3.
Connect a single-phase 200-V AC input to terminals L1 and N/L3.

current (mA)
Guide of leakage current: If a CV wire is used and routed through a metal pipe,
the leakage current is 30 mA/km.
Due to the higher specific inductive capacity of the H-IV wire, the leakage current
increases about eight times. Use a wire with a sensitivity current one-level higher.
The leakage current mentioned here is the effective value of the fundamental
wave, and high-frequency currents are excluded.
