7. Electrical connection
7.1. Power supply
The electrical connection must be made by a quali
fi
ed
person and must be registered with the local electric-
ity company. The executive electrical company, is
responsible for the norm-compliant connection to the
electrical installation and the applied safety measure.
The mains voltage at the terminals of the heat pump
must be 230V respectively 400V ± 10%. The dimen-
sions of the connecting cables must be checked by
the executive electric company.
A fault-current circuit breaker for the heat pump
is not required. The connection to the protective
measure „protective multiple earthing“ is su
ffi
cient.
If nevertheless the protective measure „fault-current
circuit breakers,“ dispatched by the executive electric
company, a separate fault-current circuit breaker for
the heat pump is recommended.
All electrical details can be
derived from the appropriate
circuit diagram.
This must be designed as an all current sensitive
Type B time-delayed (I
Δ
N
≥
300mA).
The speci
fi
ed FI-types related to the heat pump ex-
cluding externally connected components (see Instal-
lation instructions, data sheets).
For the main current circuit as a result of the occur-
ring starting currents, circuit breakers with a tripping
characteristic curve Type „C“ or „K“ must be used.
For the control circuit and the optional electric auxiliary
heater, circuit breakers with a tripping characteristic
Type „B“ or „Z“ are su
ffi
cient.
The electrical connection- and supply cables must be
designed as copper cables.
For electrical details see the wiring diagram.
