Electrical connection of the power cable
DANGER
Connecting the device to the power source can only be performed by a qualified installer in
a
voltage-free
state.
CAUTION
The cable must be routed through the cord anchorage installed before the connecting
terminals in the indoor unit. Make sure the cable connected in the indoor unit is relieved from
strain.
CAUTION
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.
CAUTION
In case of connecting the multi-wire flexible cable to the connecting clamp, it always has to
have a necking die at the end.

Necking die
2
Multi-wire flexible
cable
3
Massive single-wire cable
To connect to connecting clamps of the device, use cables with necking dies or a massive
single-wire cable.
Connecting clips of the supply cable
Connect the electrical supply (3N ~ 400 V / 50 Hz) to the connecting clips L1, L2, L3, N and
PE (
). For choosing the appropriate diameters of the cables, see technical data (chapter 6.2).
Connect the connecting clamp 1 with a connecting wire to the connecting clamp on the
circulation pump of the heat source.
Connecting clamp 3, see chapter 3.4.1.
The stationary phase ~ 230 V, 50 Hz is connected to connecting clamp 5.
