1.3 Warnings

The warnings used in this installaon guide idenfy safety-relevant informaon.
They consist of:

1.4 General informaon

The manufacturer of the PV system must be consulted before the installaon in order to ensure that the exisng
roong and roof substructure is designed to support the addional loads. The condion of the roof substructure must
be checked via the installer (e.g. the quality and strength of the purlins, if necessary also the raers and roof baens,
the quality of the roong, adequate aachment of the roof covering to the substructure, and the maximum load­bearing capacity of the roof covering).

Before installing the substructure, ensure that the module manufacturer's specicaons regarding the module clamps
are observed (e.g. the width and type of the clamp as well as its mounng posion on the module). If this is not the
case, either the module manufacturer's consent must be obtained by the customer prior to installaon, or the frame
must be adapted to the module manufacturer's specicaons.

The requirements for lightning and surge protecon of installaon systems for PV modules must be met in accordance
with DIN and VDE regulaons (e.g. DIN EN 62305-1-4, DIN V VDE V 0100 Part 534, VdS data sheet 2010).
The specicaons of the respecve power supply company must also be complied with.

During installaon, re protecon regulaons must be sased; for example, re protecon walls should not be
modied and the corresponding clearances must be observed.

When changing the roong, the manufacturer's instrucons must be followed. During and aer installaon, the frame
parts must not be stood upon or used as a climbing aid. There is a risk of falling and the underlying roong could be
damaged.

Before carrying out work on the roof, check that all accident prevenon regulaons have been complied with (in their
current version), and that sucient protecon against falling objects has been provided.

The installaon should only be carried out by adequately trained specialists who work in accordance with the rules of
the German roong trade (ZVDH).

This installaon guide is based on state-of-the-art technology as well as our long-standing experience
of installing our systems in situ. Since individual project-specic features must be taken into account
for each roof, it is always necessary to seek expert advice
before starng the installaon.
In addion, the manufacturer of the photovoltaic system must be consulted before the installaon, in
order to ensure that the exisng roong and roof substructure is designed to support the addional
loads.
Structural engineers should aend the site for this purpose.
Each photovoltaic system must be installed in accordance with the structural requirements of the site
and the installaon situaon, taking into account the informaon contained in this installaon guide.

Ensure that only current and complete installaon guides are used during the installaon and that a
printout of the installaon guide is kept in the immediate vicinity of the system.

Subject to technical modicaons.

When installing the PV systems, always observe the installaon instrucons provided by the module
manufacturer, as well as the relevant standards, accident prevenon regulaons, and any other
applicable regulaons and
provisions.

Before installaon, the manufacturer of the photovoltaic system must be consulted in order to
ensure that the installaon is strictly carried out in accordance with the naonal and site-specic
building regulaons, safety and accident prevenon regulaons, relevant industrial standards and
environmental protecon regulaons.

All individuals who install S:FLEX PV installaon systems are obliged to independently inform
themselves about all relevant rules and regulaons relang to proper planning and installaon, and
to adhere to them during the installaon process. This also includes checking the current state of the
various rules and regulaons.

The applicable local and naonal direcves regarding occupaonal health and safety and
environmental protecon must also be respected.

Module approvals: a list of approved modules is available from S:FLEX GmbH;
request individual approvals from the module manufacturers
Materials: supporng brackets made of aluminium EN AW 6060 T64, module clamps made of aluminium
EN AW 6063 T66, stainless steel screws, wind deectors made of galvanized steel
Requirements: the structural load-bearing capacity of the roof and the roof insulaon must be ensured by the customer;
the general business and warranty condions as well as the user agreement apply

Modules

The system requires that modules with this type of fastening (clamp on the module's short side) can also be used. This approval
may exist either generally within the scope of the module cercaon or may be granted by the module manufacturer on a
project-specic basis.

Flat-roof coverings

The LEICHTmount 2.1 E/W can be installed on the following at-roof coverings:
foil, bitumen, gravel, green, concrete.

The compability of the roof covering and the protecve mats must be ensured. The roof covering (and possibly the insulaon
layer) must be able to absorb the pressure loads of the PV system. The fricon coecient of the exisng roof covering is used as
the basis for the ballast chart and must be determined by the customer.

If the roong gravel lies directly on the water-bearing roof skin, the system must not be placed on the gravel layer. In this case, the
gravel must be removed in the area of the brackets.
