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 absolutely be observed. For
your own safety and to safeguard your solar module,
please observe the following safety guidelines:
Important Notice!
„ During the setup and maintenance of solar modules,
the valid regulations and safety guidelines for the in-
stallation 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 insulation
fi lm at the reverse) may not be set up.
Damage to the insulation fi lm at the reverse has severe
potential consequences (delamination, endangerment
of life and health).
„ Defi nitely align the solar module so as to avoid a sha-
dowing eff ect (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. formation 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 cur-
rent can lead to light arcs. Therefore, prior to perfor-
ming any work on the solar system – particularly prior
to separating the plug connectors in the direct-current
circuit – it is essential to disconnect the frequency
inverter from the alternating-current grid.
„ For roof-mounted systems, the modules must be atta-
ched above a fi reresistant surface.
„ Solar modules may not be installed near easily-fl amma-
ble substances, gases or vapors.
„ The guidelines on fi res in electrical systems (e. g.
VDI 3819) apply hereto.
„ The maximum permissible totalsystem voltage for the
frequency inverter may never be exceeded. In addition,
due to the negative temperature coeffi cient of the solar
modules, the atrest voltage of the total system at the
minimum permissible temperature must also be calcu-
lated (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 follo-
wed.
„ 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.
