Scope of application
– This system has been designed solely for the generation of electricity from solar energy
and as weather protection�
– The mounting of full-surface PV installations, where the PV eld extends to the roof edges,
is possible, but is not covered by these mounting instructions�
– Solrif
®modules are solely designed for in-roof mounting in accordance with this manual�
– Information on electrical connections, earthing and wiring can be found in the relevant plans
and component instructions�
– Correct use includes observing all the information in this manual�
– These instructions apply to the Solrif
®N as well as to the Solrif ®D system�
– The sheet metal surround is designed and tested for typical interlocking tiles� Its suitability for other
roof coverings or connection to roof edges and roof superstructures must be assessed by a specialist;
if necessary, transition sheets must be made by a roong materials specialist. Suggested solutions
can be found at www�solrif�com�
Any use of the system that goes beyond correct use, as well as any different use of the system or of the
Solrif
®modules, counts as incorrect use and can lead to dangerous situations�
Illustrations in this manual are intended for basic understanding, and may deviate from the actual design
of the system�
Exclusion of liability
– The information and safety instructions in this manual have been compiled taking into account the
currently applicable norms, guidelines and regulations, the latest technology and the accumulated
experience of Ernst Schweizer AG�
– The shipment contents, or the design of the system, can deviate from the descriptions and diagrams
specied in this manual because of optional items ordered, manufacture of customised designs or
the latest technological changes�
– Apart from the contractually agreed obligations, the manufacturer's General Terms and Delivery Conditions
apply� These are subject to the laws that were valid at the juncture when the contract was concluded�
– Ernst Schweizer AG reserves the right to make technical changes to the system as part of further
development to improve performance characteristics and safety�
– Ernst Schweizer AG accepts no liability for damages and accidents arising from the following causes:
– Inappropriate use of the mounting system
– Non-observance of the information and instructions in this manual
– Work carried out on or with the system by non-qualied or unauthorised personnel
– Yield losses due to electrical defects of the modules

Requirements for the roof
– Roof pitch: 10° to 75° (with foil underroof)
– Underlay, sub-roof membrane against condensate and moisture according to ZVDH/SIA 232/1,
temperature resistance up to 80° C
– Wooden substructure: analogous to tiled roof or on vertical counter battens�
– Wood quality: Strength category C24
Allow an additional requirement of 10% for wood offcuts compared to the batten plan� In addition,
keep a range of auxiliary material to hand to smooth out any irregularities in the roof construction or
to be able to implement connections or linings�
Note
Permissible deviation from the atness of the substructure 0,5 % (5 mm per metre)
Note
Stepping on modules that have already been laid can lead to cell breakage and, in the long term,
to a reduction in performance� If unavoidable, please follow the manufacturer’s instructions or only
use the appropriate devices�

Hazards due to electrical energy
WARNING
– Solar modules produce electricity when light falls on them�
– Have work on the electrical system carried out only by qualied electricians.
– Observe the regulations applicable at the installation site�
– If modules are found to be damaged, please contact the supplier�
– In case of damage to the cable insulation, immediately disconnect the power circuit
and arrange for repair�
– Do not connect or disconnect cable assemblies if they are carrying current�
– Make sure that the maximum permissible system voltage is not exceeded when connecting
the modules in series�
Note
– Make sure that when modules are connected in parallel, each row is individually protected
by a fuse�
– Observe the instructions of the module manufacturer and of the system planner�
– Observe the information sheet on equipotential bonding and lightning protection at
www�solrif�com�
Transport and packaging
Please observe the handling instructions on the packaging� If the goods or the packaging show any defects,
please contact the supplier�
– Do not set the module down on its glass rim� Risk of damage to property!
– Leave the module in its original packaging until immediately prior to insertion into the PV array�
– Never hold or carry the module under any circumstances by its connection cables or junction box�

Preparation
Before installation, the following documents must be checked for completeness and taken into account:
– Solar�Pro�Tool documentation (SPT), incl� parts list and CAD plan
– Electrical planning (cable routing plan)
– Protection concepts (lightning protection, earthing, equipotential bonding)
– Roof Plan
Working area
– Safety equipment such as scaffolding etc� must be professionally installed before installation�
– Observe the local and national regulations for the installation of PV systems, safety equipment and
electrical systems�
– Check goods and auxiliary equipment for completeness and damage�
Solrif
®N to Solrif ®D
The mounting of the two systems is identical. The systems differ in the module frame and edge prole
geometry, which means that different mounting brackets are required� The same grid dimensions are
assumed for both systems�

® N proles Solrif ® D proles
Earthing
If the modules are earthed, then attach the earthing terminal* (article number 21899) as follows:
Preparation: Screw on earthing terminal To connect: Remove 30 mm insulation of the
earthing cable and press into earthing terminal

Maintenance and cleaning
Unless otherwise specied by the module manufacturer, it is recommended to check the PV array for
damage annually and after severe weather events such as storms or hailstorms� In case of heavy soiling, it is
recommended to clean the modules and module drainage channels� If the yield changes, the electrical
installation must be checked by a specialist�
Replacing modules
1� Move the module to the left of the defective module upwards, e�g� with the aid of glass suction cups,
until it comes free from the mounting brackets at the lower edge (when replacing modules at the left edge
of the generator eld, the edge prole must be pushed upwards).
2� Lift up the right-hand corner of the module to the left of the defective module by about 3 to 5 cm and
secure the module in this position using a wooden wedge�
3� Shift the defective module upwards until it detaches from the mounting clamps on the bottom edge�
4� Lift up the defective module by the bottom edge and pull it downward and out�
5� Disconnect the connections to the neighbouring modules in the cable group and secure the loose cable
ends of the neighbouring modules so that these do not ‘disappear’ between the PV array and the roof
underlay�
6� Disconnect the equipotential bonding cable�
7� Remove the defective module�
8. Thread the replacement module under the lifted module or edge prole to the left of it until the equipoten-
tial bonding cable can be placed in the earthing terminal, and clamp it in place again�
9� Establish connections to the neighbouring modules in the cable group�
10� Now push the replacement module further under the module above it (at the upper edge of the generator
eld: under the connection plate) until the stop point is reached and lay it down.
11� Pull the replacement module downwards until it clicks into place into the bottom mounting clamps�
12� Remove the wooden wedge under the right-hand bottom corner of the module to the left of the replace-
ment module�
13. Pull the module or the edge prole to left of the replacement module downwards until it clicks into place
in the lowermounting clamps�
Disinstallation and disposal
Disinstallation and disposal of PV systems may only be carried out by qualied specialist rms. Have
dismantling and disposal carried out only by a specialist company for roof-integrated photovoltaic systems�
