Be sure to use either 2-core sheathed vinyl cord or cable as mentioned below.
Cautions:
1. Never use a 3 or more core of cord or cable.
2. The size of wire should be 0.75~1.25mm².
3. Never bundle the cable or cord of transmission line.
4. Be sure to keep the transmission wiring distant from power wiring as shown below to prevent electrical noise.
Note:

cause the malfunction in transmission.
