Connection of power cable
Connecting the device to the power source can only be performed by a qualified installer in a volt-
age-free state!
• The supply and communication cables have to be laid into the device and electrical cabinet
through separate envisioned ducts and overflows which are installed before the cable clamp. This
way we ensure the cable is relieved and the electrical cabinet is protected from water penetration.
• Wrong dimensioning of the power cable or too weak terminal fuses of the device could lead to an
overload of the safety elements on the power grid of the building which could lead to overheating
of the electrical installation. Follow the requirements listed in this manual.
• Multi strand flexible cables must be connected to the indoor unit terminal blocks with crimped end
sleeves.
Solid core wires do not need crimped end sleeves.
• The device comes with an electrical heater 3 x 2 kW. The power supply is connected according to
your needs:
a) ~ 230 V / 50 Hz on the connecting clips L1, N and PE,
