Danger
Damaged cable insulation can cause injury and
damage to the appliance.
Route cables so that they cannot touch very hot,
vibrating or sharp-edged components.
Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
■
Route LV leads < 50 V and
>
50 V/230 V~/400 V~ cables separately.
■
Strip the cables of a small amount of insulation
close to the terminals and bundle tightly to the
corresponding terminals.
■
Secure cables with cable ties/strain relief fit-
tings.
This ensures that, should there be a fault, for
example when detaching a wire, the wires can-
not drift into the adjacent voltage area.
When routing on-site power cables, observe the loca-
tion of the cable entries into the appliance through the
back panel (see page 14).

1.
Route LV leads through "< 50 V" entry to heat pump
wiring chamber.
2.
Route 230 V cables through "230 V" entry to heat
pump wiring chamber.
Secure 230 V cables with cable ties.
Note
Route LV leads and 230 V cables far apart.
3.
Route power cable for compressor through "400 V"
entry to the heat pump wiring chamber.
Always
secure the power cable with strain relief fit-
tings.
Note
On-site strain relief fittings are required since the
wall clearance is ≥ 80 mm.
For power supply, see from page 37.
