The amount of line-conducted interference also increases as motor cable length increases.
Adherence to the interference limits for line-conducted interference is shown as follows:
Filter: FPF-9120-10-SW, FPF-9120-14-SW, FPF9120-24-SW (Switch position 1: High leakage current)
EN61800-3 Cable length
Category C1 25m Max.
*1
Category C2 50m Max.
*1: The inverter needs to be installed in a metal cabinet to meet category C1. Otherwise category C2.
Filter: FPF-9340-05-SW (Switch position 1: High leakage current)
EN61800-3 Cable length
Category C2 50m Max.
