Carrying out the electrical installation
Danger!
Risk of death from electric shock!
A continuous voltage is always present on
the mains connection terminals L and N.

mains by de-energising the product using
a partitionb with a contact opening of at
least 3 mm (e.g. fuses or power switches).
Danger!
Risk of death from electric shock as a res-
ult of an improper electrical connection!
An improper electrical connection may neg-
atively affect the operational safety of the
product and result in material damage or per-
sonal injury.
▶
The electrical installation must be carried
out by a suitably qualified competent per-
son who is responsible for complying with
the existing standards and directives.
Caution.
Risk of damage to the electrical lines as a
result of high temperatures.
The electrical lines may be damaged by the
high temperatures from the solar fluid that
flows through the copper pipes.
▶
Make sure that the electrical lines are
not positioned directly next to the pipes
through which the solar fluid flows.
▶
For the electrical installation of the product, observe the
technical connection requirements for connecting to the
low-voltage network of the power supply network oper-

Connecting the shift-load switching valve
Note
If a UV5 shift-load switching valve is included in

use a 3-way valve from the Vaillant range of ac-
cessories and connect this using the connection
cable that is also available as an accessory.
