● Solution for noise
(A) Make the wiring with caution for the following points from the noise creation source.
(B) Make the wiring for the input circuit with placing the gap from the power circuit and ground circuit.
(C) Use the shield line for the noise from the electrostatic induction.
(D) Connect the shield line to the ground terminal according to the necessity not to make the 2 point ground.
(E) Make the wiring in tight twisting for the noise from the electric induction.
1-3. Wiring
