It is important to keep the power supply and the transmission wiring separated
from each other. In order to avoid any electrical interference the distance between
both wirings should ALWAYS be at least 50 mm.
NOTICE
Be sure to keep the power line and transmission line apart from each other.
Transmission wiring and power supply wiring may cross, but may NOT run parallel.
