Safety instructions explained
Danger
This symbol warns against the
risk of injury.
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively
designed for qualified personnel.
■ Work on electrical equipment must
only be carried out by a qualified elec-
trician.
■ The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
Regulations
Observe the following when working on
this system
■ National installation requirements
■ All legal instructions regarding the pre-
vention of accidents,
■ All legal instructions regarding envi-
ronmental protection,
■ The Code of Practice of relevant trade
associations
■ All current safety regulations as
defined by DIN, EN, DVGW, VDE and
all locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI and SWKI
Working on the system
■ Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing the separate fuse or
by means of a main isolator.
Note
In addition to the control circuit, there
may be several power circuits.
■ Safeguard the system against unau-
thorised reconnection.
!Please note
Electronic modules can be dam-
aged by electrostatic dis-
charges.
Before beginning work, touch
earthed objects, such as heating
or water pipes, to discharge static
loads.

Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of your sys-
tem.
Replace faulty components only
with original Viessmann spare
parts.
Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the system can compromise
its function. Installing non-author-
ised components and making
non-approved modifications or
conversions can compromise
safety and may invalidate our
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.
