8. Electrical connection
8.1. Power supply
Electrical connection must be registered with the
relevant power supply company.
The necessary series-connected fuse for the primary
circuit can be found in the technical data. It is essential
that a fuse design is used (“C” or "K" characteristic).
The relevant cable cross section must be determined
by the electrician.
All systems are equipped with a start-up current limiter.
The heat pump is operated via the Navigator Control.
Depending on system design, the relevant sensors
are required; see the connection diagrams on the fol-
lowing pages for more information.
For reliable operation of the heat pump, the voltage in
the mains network must be within specifi c tolerance
limits, between 360 and 430 V (check with the rel-
evant power supply company if necessary).
The connection cables between the control cabinet and the heat pump are not included in the
scope of delivery. The layout of the respective line cross section for the compressor must be
carried out by an electrician according to the technical data (see page 6). The power consumption
of the compressor can also be taken from the wiring diagram enclosed.
