Note 1. Use shielded twisted-pair cables, but do not connect the shield.
2. When an input is not being used, short the + and – terminals.
3. Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
4. When there is noise in the power supply line, install a noise filter on the input
section and the Power Supply Unit.
