Daikin FUQ71CVEB Installation Manual page 27

• Keep the distance of 50mm or more between the low voltage wiring (remote controller wiring) and the
high voltage wiring (transmission wiring, earth wiring) at anywhere outside the indoor unit. If both the wir-
ings are laid down together, they may be affected by electric noise (outside noise) and cause malfunction
or failure.
WARNING
When wiring, form the wiring orderly so that the control box lid can be securely fastened.
If the control box lid is not in place, the wiring may float up or be sandwiched by the box and the lid and
cause electric shocks or a fire.
