※
Ensure that the design is safe by installing protective functions on the input side of the
main circuit using breakers or other devices.
※
If the power supplied to the main circuit is not 200/220 V, use a transformer to change
the control power supply to 200/220 V.
※
Wire the main circuit and control circuit with the correct polarities.
