1.
Route extra low voltage (ELV) 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 extra low voltage (ELV) leads and 230 V
cables far apart.
3.
Route power cable for compressor through
"400 V~" entry to 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 page 50 onwards.
Overview of electrical connections
Note
■
Route 230 V~ cables and extra low voltage (ELV) leads separately and bundle them tightly together at the ter-
minals. This ensures that, in the event of a fault, e.g. if a wire becomes detached, the wires cannot drift into the
adjacent voltage area.
■
Strip as little of the insulation as possible, close to the terminals.
■
If 2 components are connected to the same terminal, press both cores together in a
single
wire ferrule.
