Determining the 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 VD is calculated as follows:
Ǹ
VD (V) =
x wire resistance (Ω/km) x wire length (m) x amperage (A) x 10–3

H Conformance to EMC Directives
D Wiring Power Supply
Install the Inverter and Noise Filter on ground plates.
Be sure to wire the Inverter through a dedicated Noise Filter.
Reduce the length of the ground wire as much as possible and connect the ground wire to the ground
securely.
Reduce length of the cable between the Inverter and the Noise Filter as much as possible. The cable
length must not exceed 400 mm.
