8.3 Making electrical connections
1. Extend the pre-installed power cable of the heat
pump (W1, approx. length 1.8 m) with a 3-core pow-
er cable (3G 2.5 mm²)
Alternatively: Uninstall the pre-installed power ca-
ble of the heat pump and replace it with a 3-core
power cable (3G 2.5 mm²) of the required length.
Strip the sheathing off the new power cable and
wrap it around the ferrite core in the same man-
ner as the original cable was wrapped around the
ferrite core.
2. Route the power cable into the building to the hy-
draulic tower HT 7.
3. Route the communication cable (W2) through the
cable bushing (UB2) from outside into the heat
pump.
