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.

the terminal block (symbols P1, P2) and fix the cable with a tie wrap.
3 Transmission cable: Route the cable through the frame, connect the cable to
the terminal block (make sure the symbols F1, F2 match with the symbols on
the outdoor unit), and fix the cable with a tie wrap.
4 Power supply cable: Route the cable through the frame and connect the
cable to the terminal block (L, N, earth).

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.
