2.5 Notes on electrical noise
Electrical noise emitted by other instruments can cause failures.
Note the following points when designing an electrical power equipment plan:
The branch circuit of a power supply to the Device should not be accompanied with
devices or instruments that have a relay or micro switches to turn it on and off
repeatedly, such as air conditioners.
The service ground terminal of the device (Type D grounding) should directly
connect to the ground plate or, if possible, a dedicated ground system for the Device.
As for the devices and the instruments emitting electrical noise, embed a circuit to
prevent noise generation.
The cables connected to the Device are roughly categorized into power cables and
signal cables, which are basically different in electrical characteristics. Avoid banding
or twisting both types of cables when laying them.
Do not route the communication lines along the power cables.
