Please read the installation and operating man-
ual completely before transporting, installing or
operating the solar modules. It contains impor-
tant safety instructions. The warranty will be
void if you fail to follow the instructions in this
manual when using the solar modules.
This documentation is current as of January
2009. We reserve the right to update the infor-
mation it contains without prior notice.
1. Safety instructions
Electrical installation and initial operation may
only be carried out by licensed electricians in
accordance with the instructions below. Im-
proper installation or initial operation may re-
sult in damage to property and injury to per-
sons. Personal fall protection systems should
be used when working on rooftop solar genera-
tors. All applicable occupational health and
safety regulations must be followed. For your
own safety and to protect your solar module,
please observe the following instructions:
Notes:
When carrying out installation and main-
•
tenance work on solar modules, comply
with all applicable regulations and safety
precautions relevant to the installation of
electrical equipment and systems, as well
as the regulations issued by your electric-
ity supply company concerning grid-
parallel operation of solar power sys-
tems.
Make sure that the solar module is fully
•
intact before installing it.
Damage to the rear surface insulation
•
film can have serious consequences (de-
lamination, danger to life and health). Do
not install or operate a module with
damaged rear surface insulation film.
When modules are connected in series
•
(addition of module voltages), voltages
may occur in excess of the safety extra-
low voltage of 120 V DC.
Module usage class: A
•
Note that a full open circuit voltage is
•
generated in the modules even at low
ambient light levels.
Disconnecting the direct current of live
•
cables leads to arcing. Be sure to discon-
nect the inverter from the AC mains grid
before carrying out any work, especially
before disconnecting the plug connectors
in the DC circuit.
In the case of rooftop systems, modules
•
must be installed on a fire-resistant sub-
surface.
Solar modules must therefore never be
•
installed near easily flammable materials,
gases or vapours.
Observe all guidelines regarding fires in
•
electrical systems.
The maximum permitted system voltage
•
of the solar modules must never be ex-
ceeded, even at low temperatures (see
data sheet and module type plate).
Handle solar modules as you would a
•
glass product and do not walk or step on
them.
Never leave a solar module in a free-
•
standing or unsecured position.
Do not install solar modules with broken
•
glass.
Do not make any changes to the struc-
•
ture of modules.
Comply with the safety instructions pro-
•
vided by the manufacturers of all other
components in the solar power system.
2. Positioning instructions
To ensure the highest annual energy output
possible, we recommend a module position that
meets the following criteria:
Align the front of the solar module so it
•
faces south.
In Germany, select a tilt angle based on
•
local and structural conditions (30° ±
15°). Specific instructions on optimal
module positions can be found in the
relevant technical literature. The tilt angle
may be calculated using the following
formula: tilt angle = latitude of place of
installation –20°.
