Note!
Use 60°C / 75°C copper conductor only.
External fuses of the power section
The inverter must be fused on the AC Input side.
Use fast-acting fuses only. Use the fuses shown in the table below.
Connections with three-phase inductance on AC input will improve the DC link capacitors life time.

Input chokes
The three-phase mains choke is strongly recommended in order to:
- limit the RMS input current of the AGL50-EV inverter.
- increase the life of intermediate circuit capacitors and reliability of input diodes.
- reduce the harmonic distortion of the current absorbed by the grid to typical values of 70% (with rated current)
