*1 Unused channels shall basically be short-circuited. (Voltage signal terminal - Current signal terminal - GND)
The signal terminal on the unused side of the used channel must be open.
Example: When CH0 is used as voltage input, II0+ terminal must be open.
*2 Ground shielded wires at one point on the PLC side (Grounding resistance of 100Ω or less). However, when shielded wires
had better be grounded on the external device side due to the condition of external noise, their ends on the PLC side must
be open.
*3 Keep signal wires that go out of the analog unit sufficiently away from high-voltage or power cables, and avoid parallel wiring.
*4 Avoid wiring the signal cables in the vicinity of load cables coming from devices other than PLC or bundling them with such
cables.
*5 Keep the signal cables sufficiently away from circuits where high frequencies occur, such as inverter main load circuit.
*6 It is recommended to connect a ceramic capacitor (0.1 to 0.4μF) to reduce noise.
