To connect the electrical wiring on the
indoor unit
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.
