22 Electrical connection work
The following applies to all work to be done:
DANGER
Risk of fatal electric shock!
All electrical connection work must be
carried out by qualified electricians only.
Before opening the unit, disconnect the
system from the power supply - wait for 90
seconds = residual voltage at inverter - and
prevent it from being switched back on!
WARNING
Note and follow the relevant EN, VDE and/or
local safety regulations during installation
and when carrying out electrical work.
Comply with technical connection require-
ments of the responsible power supply
company (if required by the latter)!
22.1 Power connection
1. If the unit is closed, take off the facing panel.
2. The power cables are pulled through the opening
in the baseplate and are routed through the cable
duct and into the switch area.

20 Water heating
Water heating with the heat pump requires another
heating water circuit in addition (parallel) to the heating
circuit. When integrating, make sure that the hot water
supply is not fed through the buffer tank of the heating
circuit.

21 Hot water tank
If the heat pump is to be used to heat water, you
must integrate special hot water tanks in the heat
pump system. Choose the storage volume so that the
required quantity of hot water is available even during
a power cut.
The heat exchanger surface of the hot water tank must
be dimensioned so that the heating capacity of the
heat pump is transferred with minimum temperature
drop. We offer a variety of hot water tanks for you to
choose from. They are optimally matched to your heat
pump.
Integrate the hot water tank in the heat pump system
as shown in the hydraulic diagram for your system.
