Routing the cables to the heat pump wiring chamber

Danger
Damaged wiring insulation wiring can lead to
serious injury from electrical current and result in
appliance damage.
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.
Take the following measures to prevent drifting
of wires into the adjacent voltage area:
Route LV leads < 42 V separately from cables
■
42 V/230 V~/400 V~ and secure with cable
>
ties.
■ Only strip the minimum of insulation from
cables as close as possible to the terminals
and bundle tightly to the corresponding termi-
nals.
■ If 2 components are connected to the same
terminal, press both cores together in a single
wire ferrule.
