2 Safety guidelines
The setup and commissioning of the electrical system
may only be performed by a specialist electrician in
observance of the following guidelines, since improper
performance of this work can lead to damage and injury.
When performing work on solar generators – primarily
on roofs – suitable safety precautions (e. g. fall arresting
devices) must be used. The regulations set forth by
Employers‘ Liability Insurance Associations must absolu-
tely be observed. For your own safety and to safeguard
your solar module, please observe the following safety
guidelines:
During the setup and maintenance of solar modules,
the valid regulations and safety guidelines for the
installation of electrical devices and systems, as well
as the regulations set forth by the competent energy
supply company for the parallel grid operation of
solar power systems.
Prior to setup, the solar module must be inspected
for mechanical soundness. Damaged solar modules
(e. g. modules with broken glass, damage to the insu-
lation film at the reverse) may not be set up.
Damage to the insulation film at the reverse has se-
vere potential consequences (delamination, endan-
germent of life and health).
Definitely align the solar module so as to avoid a
shadowing effect (even to a temporary or partial
extent: e. g. due to roof dormers, trees), since this
can lead to damage in the solar modules (e. g. forma-
tion of „hot spots“), failure of the PV generator and
loss of output.
The serial connection of the modules (addition of the
module voltages) may result in voltages above the
safety extralow voltage of 120 V DC!
Application class of the modules in accordance with
IEC 61730: A
Even when the light intensity is low, one must reckon
with the full atrest voltage of the modules – that is to

say, in the course of setup, one must always exercise
the greatest caution with regard to electrical faults
(e. g. short circuits).
The separation of conductors which carry direct
current can lead to light arcs. Therefore, prior to
performing any work on the solar system – particular-
ly prior to separating the plug connectors in the di-
rect-current circuit – it is essential to disconnect the
frequency inverter from the alternating-current grid.
For roof-mounted systems, the modules must be
attached above a fireresistant surface.
Solar modules may not be installed near easily-flam-
mable substances, gases or vapors.
The guidelines on fires in electrical systems (e. g.
VDI 3819) apply hereto.
The maximum permissible totalsystem voltage for the
frequency inverter may never be exceeded. In additi-
on, due to the negative temperature coefficient of the
solar modules, the atrest voltage of the total system
at the minimum permissible temperature must also
be calculated (see data sheet and module type sign).
The solar module is to be treated as a glass product
and may therefore not be used or walked on under
any circumstances in the transport container or used
as a placement area (e. g. for toolboxes), since this
can lead to visible or even invisible damage (e. g.
microcracks in the cells and with that, a premature
drop in output – among other faults).
The module frames may not be drilled, nailed or
welded to a contact surface.
The solar modules may not be held or transported by
their connector cables or by the connector socket.
Solar modules may never be left standing freely or
unsecured.
The safety guidelines set forth by the manufacturers
of other components of the solar system must be
followed.
The drainage drill holes in hollowchamber frames may
not be covered.
Solar modules made by Bosch Solar Energy are not
regulated construction products in the context of the
DIBt (Deutsches Institut für Bautechnik – German
Institute for Construction Engineering) and may not
be used as overhead glazing.
