1.1 Action-related warnings
The action-related warnings are classified in accordance
with the severity of the possible danger using the following
warning symbols and signal words:

1.2 Intended use
There is a risk of injury or death to the user or others, or of
damage to the product and other property in the event of
improper use or use for which it is not intended.
Photovoltaic modules are designed as stationary power
generators for photovoltaic installations in combination with
a suitable inverter.
The photovoltaic modules must never be used for mobile
operation or a façade installation. It is not permitted to use
mirrors or lenses to concentrate the sunlight on the surface
of the module.
Intended use includes the following:
– Observance of all other applicable documents for the
product and any other system components
– Installing and fitting the product in accordance with the
product and system approval
– Compliance with the inspection and maintenance condi-
tions.
Intended use also covers installation in accordance with the
IP code.
Any other use that is not specified in these instructions, or
use beyond that specified in this document, shall be consi-
dered improper use.
Any direct use in industrial or commercial processes is also
deemed to be improper.
1.3 General safety information for the end user
and competent person
Danger caused by improper operation
Improper operation may present a danger to you and
others, and cause material damage.
> Carefully read the enclosed instructions and all other
applicable documents, particularly the „Safety" section
and the warnings.
> As the end user, you should only carry out those activi-
ties for which these operating instructions provide inst-
ructions.
Risk of death from electric shock
Photovoltaic modules can create a high DC voltage at any
time.
> Keep away from current-carrying components.

Imminent danger to life or risk of severe
personal injury
Risk of death from electric shock
Risk of minor personal injury
Risk of material or environmental
damage
Risk of injury and material damage due to mainte-
nance and repairs carried out incorrectly or not
carried out at all
> Have faults and damage eliminated immediately.
> Adhere to the maintenance intervals specified.
Risk of death caused by missing fall protection
> Secure people and material against falls.
1.4 General safety information for the
competent person
Risk caused by inadequate qualifications
All of the work that is described in the installation and main-
tenance instructions must only be carried out by sufficiently
qualified competent persons.
> Proceed in accordance with current technology.
Risk of death from electric shock
There is a risk of death from electric shock if you touch live
components.
Before commencing work on the product:
> Disconnect the product from the power supply by swit-
ching off all power supplies at all poles (electrical parti-
tion with a contact gap of at least 3 mm, e.g. fuse or cir-
cuit breaker).
> Secure against being switched back on again.
> Check that there is no voltage.
> Ensure that the insulation is not missing or defective.
When the photovoltaic module is de-energised and earthed,
this may result in a high voltage.
> Before carrying out any electrical work on the photovol-
taic module, remove the earthing from the photovoltaic
module.
The photovoltaic modules generate high DC voltages even
when the light incidence is low.
> Never touch the electrical connections without wearing
protective gloves.
> When working on the cabling, de-energise the photovol-
taic installation as described in the instructions for the
inverter.
> Always use a suitable insulated tool.
> Cover the photovoltaic modules with an opaque plastic
film or a fleece.
If the connections are not established or disconnected pro-
perly, this may lead to an arc forming.
> Avoid working on electrical components when the inci-
dence of solar radiation is high.
Damage to the insulating film on the rear of the photovoltaic
module may lead to a potentially lethal electric shock, fire or
severe burns.
> Prevent sharp or pointed objects from coming into con-
tact with the insulating film.
> Ensure that the insulating film is not damaged.
Risk of death due to inadequate load-bearing
capacity of the roof
A roof may collapse as a result of the additional load of the
photovoltaic modules.
Additional wind and snow loads may cause the roof to col-
lapse.
> Ensure that a structural engineer has confirmed the roof
as suitable for installing photovoltaic modules.
> Only install the photovoltaic modules on a roof that has
adequate load-bearing capacity and a suitable mounting
frame.
