Wiring - Safety Precautions

In case of inputting pulses in high rate, take note of noise in wiring especially.

Use twist pair shield wires and ground in Degree 3.
Wire separately from power cable and I/O cables that cause noise.
Use stable power source as the power source for filter.
In case of 1-phase input, connect only Phase A. In case of 2-phase input, connect Phase A and B.
