NOTICE
▪
Follow the wiring diagram (delivered with the unit, located at the inside of the
service cover).
▪
For instructions on how to connect the decoration panel and the sensor kit, see
the installation manual delivered with the panel or the kit.
▪
Make sure the electrical wiring does NOT obstruct proper reattachment of the
service cover.
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.
1 Remove the service cover.
2 User interface cable: Route the cable through the frame, connect the cable to
the terminal block, and fix the cable with a cable tie.
3 Interconnection cable (indoor↔outdoor): Route the cable through the
frame, connect the cable to the terminal block (make sure the numbers match
with the numbers on the outdoor unit, and connect the earth wire), and fix
the cable with a cable tie.
4 Divide the small sealing (accessory) and wrap it around the cables to prevent
water from entering the unit. Seal all gaps to prevent small animals from
entering the system.
WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small
animals. Small animals that make contact with electrical parts can cause
malfunctions, smoke or fire.
