Connection of power cable
Connecting the device to the power source can only be performed by a qualified installer in a
voltage-free state!
• The supply and communication cables have to be routed into the device and electrical cabinet
through separate envisioned ducts and overflows which are installed before the cable clamp.
This is to ensure that the cable is reliable and the electrical cabinet is protected from water
penetration.
• Incorrect dimensioning of the power cable or defective 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 short-
circuits. 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 use crimped end sleeves.
• The device comes with an electrical heater 3 x 2 kW. The power supply is connected according to
your specifications.
