12.9. Routing

WARNING
It is important to keep the high voltage, low voltage and
power supply wiring separated from each other. In order to
avoid any electrical interference the distance between both
wiring should always be at least 25 mm.
The indoor unit has several openings on the bottom side for field
wiring. Use the appropriate opening to route the high voltage, low
voltage and power supply wires as shown in the figure below.
