SAFET Y INFORMAT I ON
The system is to be installed only with ballasting in accordance with static loads. You will receive these
with the planning of your solar plant from the Schletter configurator
Risk of breakage! PV modules can be damaged if they are stepped on.
Planning of the solar power system, installation and commissioning may only be performed by qualified
personnel. Improper execution can cause damage to the system and endanger people.
Danger due to electric current! Installation and maintenance of the PV modules may only be performed
by qualified personnel. Observe the safety regulations of the PV module manufacturer!
Risk of falling! 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 are observed and that suitable fall protection devices are
used. PV mounting systems are not suitable as climbing aids or fall protection.
Risk of injury! People may be injured by falling objects. Before starting the installation work, block off
the danger zone and warn people in the vicinity.

For roofs with substrate or gravel covering, it must be considered that a low weight
load for the system can only be achieved if sliding of the system sections is reliably
prevented by an adequately slip-free connection for the substrate surface. For gravel
roofs, flush embedding of the base beams in the gravel surface is enough. For overgrown
roofs, slip resistance can be achieved with additional measures. For example,
screws in the continuous beam can be used on the construction site to create a non-slip
connection to the substrate.
NOTE ON USE OF ROOFS WITH SUBSTRATE OR GRAVELLED COVERING

MOUNTING INSTRUCTIONS
Ensure that the flat roof waterproofing is compatible with the mounting system.The roof
drainage system has to be included in the planning of your solar plant.
In the case of very uneven roofs or roof waterproofing, compensatory measures may have to be taken in
order to ensure a uniform introduction of the load.
Necessary distances to roofedges have to be maintained.
The maximum field size depends on the type of roof.
For foil roofs, it is max. 10 m; for concrete roofs, it can also be larger in individual cases.
In the case of roofs with substrate or gravel roofing, it has to be ensured that a sufficiently non-slip
connection occurs.
Please check the existing pitch of the roofandwhether the mounting system has to be secured against
slipping.
Thesurface load is not permitted to exceedthe residual load-bearing capacity of the building!
The partial surface pressure, which acts on the roof membraneand insulation underthe base rails, is not
allowed under any circumstances to exceedthe maximum permissible surface pressure.
Current country-specific rules and regulations have to be observed.
Roof cleaning! In order to ensure that the base rails are supported across their entire surface, impurities
such as moss, leaves,dirt, stones, etc. have to be removed.
If there is a lightning protection system involved, it is important to determine theextent to which
integration by a certified lightning protection company is necessary. Whether or notthe lightning
protection requirements change as a result of the installation also has to be determined.
Due to static reasons, the installation of a single module row is not permitted!
Prior to installation, the roofhas to be checked for damage of any kind, particularly water beading
or damage to the roof membrane. These should be documented with photos in order to be able to
counteract any recourse claims. The system hasbeen developed for modules with a width of 950-1050
m m (standard module dimensions according to the current status). Other module dimensions on request
and separate verification. Information about module clamping pursuant to the manufacturer has to be
observed.
The FixGrid18 mounting system is fixed to the roofpurely with ballast (except special cases). A detailed
ballast calculation can be found in the project-related planning documents. The ballasting is calculated
in such a way that sliding, tilting and lifting of the rack is avoided.
Use only original Schletter components!
No modifications to the modules are required to secure them. It is the client’s/installer’s
responsibility to ensure the clamp location is in accordance with the panel installation
manual.
All other markings, information on the number of modules and
additional information can be found in the project-specific
documents.

1. DEFINING THE BASE RAIL LENGTHSAND DISTANCES BETWEEN MODULE SUPPORTS.
This applies to modules width between 950mm and 1050mm( other modules needs a special release)
The length of the base rails depends on the selected module width, maintenance aisle width and the
number of module rows.The distance between "System Rail at the bottom" and"System Railat the top"
only dependsuponthe module inclination. The first support should be placed at least 40 mm from the
frontedge of the base rail. The module frames are always flush at the top with the Rapid 16 module clamps.
The base rail length can be selected from the six standard lengths (2150, 2650, 3150, 4200, 6000, 6300 mm)
and combined with each other. The base rails can be connected with theinternal connector, Item No.

3. MOUNTING O F THE SURFACE PROTECTIO N MAT
•After removing the protective film, gluethe cut parts of the surface protection matonto the base
rails.
•Take into account a projection of the surface protection mat of at least 30 m m at the railends.
•Marking for the mounting of the module support:
Frontedge of the module support = Distance - 28 mm
•Place the frontedge of the support on the mark; pay attention to the direction of rotation!
•Turn clockwise by 90°.
Observe suitable module and row distances for railand module mounting.
In the case of transversely flowing rainwater, the distance has to be
dimensioned on the basis of the amount of precipitation on site.
The installation distances of the surface protection mats below the base rail result from the chosen
installation variant.
Variant A
•Mount 20-mm-thick and300-mm-long strips centrally under each support
•Load introduction on a small area (for low loads and/or solid subsoil)
•An additional surface protection mat should be positioned under joints of the base rails!
•If the roof water drains off transversely, an almost unhindered drainage is possible.

10. O BSTRU C T THE BALL AST
There are basically 3 ballasting options:
•Ballasting with 100-mm-wide concrete blocks on the base rails (see Detail A)
•Ballasting with additional trough (see Detail B)
•Ballasting with additional ballast shafts (see Detail C)
•Ballasting from the combination of the 3 possibilities
Theinformation about ballasting can be obtained
with the planning of your solar plant from the Schletter
configurator.
Use fixing flaps to attach the parts of the surface protection mat to the additional trough.

LAY THE BAL L A S T WITH ADDITI ON AL BA LL AST TR AY S
If the ballast trays are filled with gravel,the gravel can be prevented from leaking at the row ends by
folding up the tray ends. To do so, the ends of the ballast trays have to be folded at the perforation.
The first ballast tray is laid from the right with the recesses
andthe upstand on the base rails.
All other trays are turned 180degrees (recesses on the left) from right to left. The tray always lies with
the side of the slots at the bottom and in the base rail with a positive fit.
At the last ballast tray, the endhas to be unfolded again.

GENERA L NOTES O N MAINTE NANC E
Yearly inspection of the system should be conducted to maintain optimal performance by qualified
personnel.
Visual inspection for
•signs of damage
•signs of wear of components
•signs of components
•position of the ballast
•position of roof protection mats
Replace any affected components immediatly: torque at module clamps must be verified with a
Torque wrenchand should be set at 50% of intended tightening torque.
Do not touch thelive part of thewire, cable and connector directly but with safery equipment
(insulating tools) when necessary.
WARNING! Contact your installer immediatly if you suspect your system is not working
properly.
WARNING! ThePV System must be shut down first if it needs any electrical
maintenance. Improper maintenance may cause lethal electric shocks/ or burns.
