1. BASICS
1.1 Notes
For the installation of the TRI-FLAT East-West mounting system only products
from the range of the TRI-FLAT South mounting system must be used. Using
third-party components can result in adverse effects on the system’s stability
and in major damages. The system may only be installed by trained and skil-
led personnel. We do not assume any liability for damages arising from the
use of third-party components or from incorrect installation.
These installation instructions describe the proper installation procedure for
the TRI-FLAT East-West flat roof system. In some situations, it is advisable, ho-
wever, to have a specialist (e.g. roofer or joiner) check the special featrues of
the roof.
1.2 Load effect
In addition to the dead weight of the photovoltaic system, mainly wind and
snow loads affect the system components and the substructure. For this rea-
son, each system must be calculated and planned for your individual require-
ments and external influences, taking into consideration DIN EN 1991*
(Actions on Structures).
The stresses by wind loads depend mainly on the wind zone (according to DIN
EN 1991-1-4*), the building’s height, the shape and slope of the roof and the
position of the roof’s centre. Weight stresses through snow load are depen-
dent on the snow zone (according to DIN EN 1991-1-3*), the building’s height,
the shape and slope of the roof and the position of the roof’s centre.
For each location the wind and snow load zone can be determined, which
will determine the design of the system.
1.3 Statics
On principle, the structural calculations of all roofs must be checked by autho-
rised experts. The main question to be answered is whether the roof can take
the additional stresses caused by the solar system.
Since the load bearing capacity of a roof and the load effect of a photovol-
taic system are determined by many factors, structural calculations must be
made for each roof individually.

1.4 Roof condition
The current condition of the roof must be such, that renovation will not be-
come necessary for a period of at least 20 years. In case of doubt, it is advis-
able to have the roof checked by an expert. The TRI-FLAT South mounting
system has been optimised for flat roofs with plane surfaces. If the roof is un-
even due to aging or other reasons, it is advisable to consult a qualified
specialist.
1.5 TRI-DESIGN dimensioning software
The TRI-DESIGN dimensioning software calculates and designs the
TRI-FLAT East-West mounting system according to the standards of DIN EN
1991 (EC)*. The relevant directives are DIN EN 1991-1-4* for wind loads and
DIN EN 1991-1-3* for snow and ice loads, which affect the photovoltaic sys-
tem and its substructure.
The dimensioning software calculates all sizes and distances relevant for the
installation. In addition, the dimensioning software allows us to design the
system optimally for the individual roof and thus to select the best version of
the mounting system.
Under the warranty terms and conditions, all TRI-FLAT East-West systems
must have been dimensioned using the TRI-DESIGN dimensioning software.

2. INSTALLATION
2.1 Tools
The TRI-FLAT bending tool is required for the installation of TRI-FLAT
East-West.
2.2 Setup
Mounting is provided in five steps:
1. Pre-mounting of the substructure
2. Preparation of the roof and setup of substructure
3. Ballasting
4. Insertion of earthing plates
5. Insertion and fixation of PV modules
2.2.1 Pre-mounting of the substructure
1. Mounting of the upper module holder
Pre-mounting of the substructure can be done on a table.
Click together the upper TRI-FLAT module holder and the module carrier.
Place the holder in the middle of the carrier.
The module holder thus pre-mounted is pushed to the stop into the TRI-FLAT
bracket.
Pre-mount another module holder and insert on the opposite side of the bra-
cket.
Note: Holders and brackets must fit together flush.
2. Mounting the central module holder
Click in the bracket between two bottom profiles. Care must be taken that
both profiles are flush together and the bracket is centred.
Subsequently, the connection between bracket and bottom profiles is bent
off at four points using the TRI-FLAT bending tool.
Note: The bend must be torn out.
3. Mounting the lower module holder
Push the TRI-FLAT clip over the lower module holder and hook in.
Centrally click together module carrier and module holder.

8_Installation
If necessary, for drainage of water, 2 holes may be drilled into the carrier of
the lower module holder in those places which module manufacturers
demand.
4. Clicking in lower module holder
Click the lower module holder into the bottom profile.
Click clip into bottom profile and push over link of the module holder.
Installation_9
5. Determine space of module holder
Place gauge onto the carrier of the upper and lower module holders with the
corresponding module width plus the module width tolerance of 2 mm (va-
lue by experience).
Push the lower module holder so far that the gauge lies flush on both bra-
ckets without any clearance
With the bending tool, bend off 1x per edge flush on the lower module hol-
der and the bottom profile.
Note: If the substructure is assembled without pre-mounting, this bending
off can be done later in Chapter 2.2.2 with the inserted series connector.
Note: The bend must be torn out.

2.2.2. Preparation of the roof and setup of substructure
1. Laying out the protective bottom mat
On the roof, the grid is drawn in accordance with the row division (RT) and
the module length + a.
a = space between two modules (e.g. 5 mm)
plus tolerance of module length (depending on manufacturer, e.g. 2 mm)
The protective bottom mats can either be cut to size or laid out directly.
As needed, the protective bottom mat is cut to size 20 mm longer than the
bottom profile and laid out according to plan in north-south direction or in
east-west direction or in both directions simultaneously.
