WARNING! When draining the water out of the water
tank all necessary precautions must be taken to
prevent damages from flowing out water.
IMPORTANT! In Denmark, Sweden, Norway and
Finland, the connection of the water heater to the
public water supply may only be performed using a
suitable pressure reducing
regulations must be observed.

Electrical connection

WARNING! Any electrical connection may only be
performed when the water heater is filled with water.
IMPORTANT!
The water heater is powered by direct
current. The water heater is protected against electric
shock "class III" and may only be supplied with safety
extra-low voltage (SELV). Only power sources
recommended by the manufacturer may be
connected. A faulty and/or unsuitable power supply
involves a high risk and is likely to cause an accident.
The connection cables of the device must be replaced
if they are damaged.
IMPORTANT! Photovoltaic modules may

connected in When connecting more than
one photovoltaic module, always use a suitable
connector for parallel connection. For more
information, refer to the illustration "Parallel PV-
Connector". Connecting photovoltaic modules in
series will damage the water heater.

The electrical connection of the water heaters is
performed using MC4 plugs. Check the functionality
of the appliance after the electrical connection has
been performed. When all supply connections are
removed, the water heater is completely
disconnected from the power sources.
CONNECTION OF PV-MODULES:
IMPORTANT!
connection of PV modules may only be carried out by
a qualified person and may not endanger third
parties. When installing the photovoltaic modules, the
locally prevailing rules and laws must be complied
with.
IMPORTANT!
tripping over them or getting caught. There is a risk of
injury. The cables must be fastened in such a way that
no tensile load is applied to the connectors.
Furthermore, it must be ruled out that the cables and
connectors rub against surfaces and edges (e.g. in
wind). The cables must not lie in water permanently.
IMPORTANT!
maximum of 60 resp. 120 cells and an open-circuit
voltage of 42.4 V may be connected.

The higher the number of hours of
sunshine per day, the smaller the
required PV power.
The warmer the water taken from the
pipeline, the lower the required PV
power.
Dimension the required photovoltaic
