2.5 Notes on electric noise

Electric noise emitted by other devices can cause failures.
Note the following points when designing a plan for the power supply facility:
The branch circuit of the power supply to the Switch should not be connected
to devices that use a relay, micro-switches, or other means to power them on
and off repeatedly, such as air conditioners.
The service ground terminal of the Switch (Type D grounding) should be
directly connected to the ground plate or, if possible, to a dedicated ground
system for the Switch.
Embed a circuit to prevent noise generation into devices that emit electrical
noise.
The cables connected to the Switch can be broadly categorized into power
supply cables and signal cables, which have different electrical
characteristics. Avoid bundling or twisting the two types of cables together
when laying the cables.
Do not route communication lines along the power supply cables.
