■ 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).
< 42 V

1. Route LV leads through the "< 42 V"
aperture to the heat pump control unit
wiring chamber and apply strain relief
using the cable ties provided. 2. Route 230 V~ cables and power
cables for the compressor through
the "230 V~" aperture to the heat
pump control unit wiring chamber and
apply strain relief using the cable ties
provided.
For power supply, see from
