3.9 Cable specification
Determine the cable size for the main circuit. The line voltage drop
should be within 2% of the rated voltage. The line voltage drop is
calculated as below:
Line voltage drop(V) = × cable resistance(
Ω
/km) × wiring length (m)
× current (A) × 10

3.10 Wiring check
• After wiring has been complete, check the following. Do not
perform a buzzer check on control circuit.
• Check if all wiring is correct.
Especially check if the power supply is connected the U/T1, V/T2,
W/T3 terminal.
• Check if any wire clippings, screws or other foreign material are left.
• Check if all screws are tight.
• Check if the load status is good.
• Check if any wire ends are contacting other terminals.
