強くして結線を行なってきた。However, this conventional device prevents noise from being generated in the low power circuit due to electromagnetic induction in the high power circuit by separately providing the terminal blocks for the high power circuit and the low power circuit within the panel as described above. If this is not sufficient, take noise countermeasures by using copper-shielded or copper-iron-shielded wires as crossover wires between panels, and make connections with stronger noise resistance to avoid practical problems.
