# For the MRCU and OVR robots are there any prevention of noise propagation tips we can use ?

## Added noise filters , keeping a good distance between signal lines , shield wires, and ground wires to prevent noise propagation.

- Connect a noise filter to the AC input side of the DC power supply.
- Keep power lines, such as motor and power supply cables, at least 200 mm (3.94 in.) away from signal lines, and do not bundle or parallel them. If a power cable and a signal cable must cross, cross them at right angles.
- Use shielded twisted pair cables for power lines and signal lines.
- Keep cables as short as possible without coiling and bundling extra lengths
- Grounding multiple points will increase the effectiveness of blocking electrical noise because the impedance at the grounding points will be reduced. However, ground them so that a potential difference does not occur among the grounding points. I/O signal cables that include a ground wire are available in Oriental Motor products.
- To ground a shielded cable, use a metal cable clamp that can maintain contact with the entire circumference of the shielded cable, and ground as close to the product as possible.
