■ Route LV cables < 42 V separately
from cables > 42 V/230 V~/400 V~.
■ Strip the insulation from the cables as
close to the terminals as possible, and
bundle tightly to the corresponding ter-
minals.
■ Secure cables with cable ties.
■ If 2 components are connected to the
same terminal, press both cores
together in a
single
wire ferrule.
This ensures that, in the event of a fault
(e.g. when detaching a wire), the wires
cannot drift into the adjacent voltage
area.
When routing the on-site power cables,
observe the location of the cable entries
into the appliance through its back panel
(see page 20).

1.
Route LV leads through opening
"< 42 V" to the heat pump control unit
terminal area.
2.
Route 230 V cables through opening
"230 V" to the heat pump control unit
terminal area.
Note
Route LV leads and 230 V cables as
far apart as possible.
3.
Route the compressor power cable
through opening "400 V" to the termi-
nal area. For power supply, see from
page 54.
