Dear customers,
With the CENPAC product from Centrosolar AG, you have
acquired a strong, high-quality product.
This reliable complete system combines the benets of
a customized PV installation with the possibilities of an
immediately available standard solution and guarantees
optimal returns under nearly all conditions. It is also un-
complicated and quick to mount.
1.1 Notes on these instructions
If you have any questions on the installation or any com-
ponents of the installation, please contact your local Cen-
trosolar ofce.
Repairing and operating a PV installation require solid
expert knowledge. This is why all work on the installation
should only be carried out by correspondingly qualied
and authorized specialist personnel. Read these mount-
ing instructions carefully and attentively before installing
and commissioning the system. Keep the instructions in
an easily accessible place. The instructions are part of the
product, they only apply to the complete CENPAC sys-
tems of Centrosolar AG. Pay special attention to the notes
on safe use. Centrosolar will not accept liability for dam-
age arising due to failure to observe these instructions.
Please observe:
Ensure that the correct safety instructions are followed for
mounting and operation. Pay attention to the relevant gen-
eral preliminary remarks from Centrosolar AG, available at
www.centrosolar.com.
Failure to observe the requirements in these mounting in-
structions can lead to the exclusion of all guarantees, war-
ranties and product liability.
The following details, notes and recommendations for
action may not be complete and should be constantly
checked to see whether they are complete and up-to-date.
1.2 Description of the mounting system
The bearing capacity of the roof in connection with the as-
sembly of a Centrosolar photovoltaic installation and the
arrangement of the fastening points are to be shown in a
structural analysis for which the building owner is respon-
sible. There is no liability on the part of Centrosolar AG for
the structural suitability of the mounting construction.
The MS Constocc Excellent mounting system basically
consists of module support proles and 2-C groove pro-
les. Please see the summary of the mounting materials
(chapter 2) for an exact overview of the necessary com-
ponents. Assembly takes place in a cross-cross arrange-
ment. This is mechanically the most stable and safe in-
stallation of photovoltaic modules. The 2-C groove proles
are constructed vertically. The module support proles are
inlaid proles fastened horizontally onto the 2-C groove
proles.
All connecting elements and system parts are manufac-
tured from aluminium or stainless steel. The system pro-
les are delivered anodized in black.
For the suitable rafter conguration of your complete
CENPAC system, please see the rafter conguration
plans in the document folder.
In case of different rafter distances, congure your rafters
according to chapter 3.3 or contact your local Centrosolar
ofce.
Proper use
Check the delivery is complete by way of packing list and
parts list before commencing the mounting. Electrical in-
stallation work that may exceed the range of the safety
extra low voltage may only be carried out by electrotechni-
cal specialists.
The mounting system MS Constocc Excellent was de-
signed solely for holding the PV modules. Any other use
is regarded as improper. Proper use also includes adher-
ing to the mounting instructions Centrosolar AG cannot be
held liable for damage resulting from failure to observe the
mounting instructions, in particular, the safety instructions
or improper use of the product.

3.2 Preliminary planning for mounting the
installation
Some preliminary planning is necessary before starting to
mounting the system.
Selecting the suitable constructions and rafter con-
guration
Calculate the available connected roof surface and rafter
distance for the installation. Select the suitable CENPAC
construction based on the roof dimensions and the nec-
essary overall dimensions of the CENPAC constructions
(see chapter 3.1). A choice must nally be made from the
rafter conguration plans (see installation instructions)
that corresponds to the distance of your rafters. Proceed
in accordance with chapter 3.3 if there is a difference in
rafter distances.
Positioning the PV installation
Position your CENPAC bearing in mind the Generator eld
dimensionsas close as possible to the centre of the roof.
Bear in mind that a margin of at least 500 mm must be
observed at all times. The actual mounting can now begin
(chapter 4).
If the distance relating to your rafters differs from that in
the drawings and you cannot carry out your rafter con-
guration yourself in accordance with chapter 3.3, please
contact your local Centrosolar ofce.
3.3 Rules relating to individual rafter
conguration
 Rafter distances of 600 – 800 mm are permitted
 Max. range that can be straddled with the module
supports: 1,500 mm
 Permissible cantilever: 50 – 400 mm
 Carry out the rafter conguration on the sides of the
generator eld on the two outer rafters
 Twice the number of roof hooks on the 2-C groove
proles in the border of the generator eld (to the
ridge, the eaves and the verges)
 Module support proles must be xed on at least two
2-C groove proles
Terminology
Overall dimensions
The overall dimensions state the free roof space that must
be available for the installation of the complete CENPAC
system in order to enable the CENPAC to be installed on
your roof safely. The overall dimensions also included the
necessary margins and an additional rafter adjustment
area as well as the generator eld dimensions.
Generator eld dimensions
The generator eld dimensions are clear from the genera-
tor surface of all PV modules of the complete CENPAC
system.
Margins
The margins stated here are safety-relevant distances of
500 mm to which your PV installation must at least adhere
to the eaves, the ridge and the verge of the roof.
Cantilever
The cantilever is the overhang of the module support pro-
les over the external 2-C groove prole in the generator
eld. The permissible cantilever may be between 50 and
400 mm. During the preliminary mounting planning, the
cantilever is dened by the overhang of the module sup-
port proles over the centre of the outer rafters.
Rafter conguration plans
These are CAD plans for the rafter conguration on the
roof. These plans for the rafter distances of 600, 650, 700,
750 and 800 mm for the individual constructions of the
complete CENPAC system are enclosed. They explain
the optimal conguration of the rafters by way of the en-
closed roof hooks, the positioning of the mounting proles
as well as the cantilever to be applied.

4 Mounting process
1 - Removing roof tiles
Select the rst rafter from the left for mounting
the rst roof hook using the rafter conguration
plan and taking account of the margins and the
maximum cantilevers to be observed.
Remove the roof tiles above the rafter to be al-
located.
It may be necessary to remove several roof tiles
from the system in order to carry out the mount-
ing depending on the individual rafter distances.
Note: Each rafter must be allocated when using
a CENPAC including the wind and snow exten-
sion package. Please observe the assembly in-
structions of the extension package.
2a - Positioning of the roof hook
The roof hooks can now be mounted onto the
cleared rafters. When positioning the base of
the roof hook, ensure that it lies at on the rafter.
Please ensure: The roof support shaft (a) may
not lie directly on the tile.
2b - Positioning of the roof hook
The roof hooks are tailored to battens 30 x 50
mm. A batten 40 x 60 mm requires the installa-
tion of separators, e.g., of 10 mm thick impreg-
nated wood. (b)
