Safety instructions
Installation instructions
The system is to be installed only with ballasting according to the design documents. You can get these from us with our system design, or directly
through software in the download area at www.schletter-group.com .
Breakage hazard! PV modules can be damaged if they are stepped on.
Planning of the photovoltaic system, installation and commissioning may be done only by qualified technical personnel. Improper installation can cause
damage to the system and endanger people.
Electrical hazard! Installation and maintenance of the photovoltaic system is to be done only by qualified technical personnel. Observe the safety
regulations of the PV module manufacturer!
Falling hazard! There is a risk of falling when working on the roof and when climbing up and down. Is it imperative that the accident prevention
regulations be observed and that suitable fall protection devices be used.
Injury hazard! People may be injured by falling objects. Before starting the installation, block off any danger zones and warn people nearby!
For very uneven roofs or roofing strips, compensation measures may be needed to ensure even application of the load.
Necessary distances to roof edges must be maintained.
Due to linear thermal expansion, the main beams must be separated by reasonable distances. A recommended reference value for the maximum bar
length on foil roofs is 10 m.
FlatGrid is not recommended for roofs with more than a 10-degree slope. For slopes of 3° and more, additional fastening may be needed on the roof.
The surface load must not exceed the building’s residual load capacity!
For static reasons, at least two contiguous rows of modules must be installed. If this is not possible, please contact Technical Advice.
Please follow any project-related instructions in the planning documentation!

!Extension of base profiles
• Extend the base profile as needed.
• To do this, insert the internal
connector into two profiles and fasten
it at both ends with two self-drilling
screws.
Tool:
Screwdriver with 8 mm plug
attachment
"Installing the structure protection mat
• Adhere the structure protection
mat strips to the existing base
profile after removing the
protective film.
• Observe at least a 30 mm
projection for the structure
protection mat at the ends of the
profiles.
#Alignment of the base profile
• Place the finished base profiles
parallel to each other on the roof in
the direction of the ridge eaves.
• The distance between the profiles
should match static specifications.
$Installing Rapid 2+ L
• Press the one-click module and square nut
into the space provided in the base profile.
• Place Rapid 2+ L onto the profile, align it,
and fasten it with a screw and shim.

Slip protection
• For sloped roofs, module fields must
be secured against slipping. Either
through horizontal fastening or
coupling of opposite tension
connectors using the tension
connector on the ridge. To do this,
thread the connectors into each other,
press them together at the ends, and
use 2 screws to fasten them from
above using a one-click module and
square nut on both base profiles.
• Roof fascia in certain circumstances
could also offer protection against
slipping. Make sure the connection
and static load-bearing capacity are
suitable.
• In general, for individual connections,
it is a good idea to consult an
engineering firm.
"
Installing the module support profiles
• Insert the module support profiles
onto the lower screw channel in the
clamp.
• Align the module support profile
vertically together with the clamping
part and tighten the screws to fasten.
#
Ballasting
• Distribute the ballast according to the
planning documents. You can get them from
our company with the system plan or
directly through the configurator in the
download area of our website:
www.schletter-group.com
• Distribute the ballast evenly on the base
profile. If the load distribution is uneven,
bring the loads close to the module support
profile.
Ballast is not included with FlatGrid.
Recommended stone dimensions: 20x10x8cm

If the base profile is not adequate for ballasting, a
tray can be filled with more stones for additional ballast.
Fasten the structure protection mat pieces to the trough
with fastening flaps.
$
Fastening the modules
• Position the module on the
module support profile
according to the plan
specifications, install the cables
and fasten with Rapid16 module
clamps.
Observe the module manufacturer’s
clamping points.
The fastening points for the module
clamps can be freely chosen in the module
support profile’s aluminum channel. The
specified torque for fastening the module
clamps is 15 Nm.
