2 Safety Instructions
2.1 Use According to Regulations
The photovoltaic system is intended solely for the generation of solar power. Mounting is to occur only upon roof
constructions in accordance with the present installation manual.
There is no guarantee for alternative applications, even if analogous. Categorically any such application is not in
accordance with regulations.
2.2 Safety Regulations
The operator of the photovoltaic system is responsible for seeing that all relevant legal regulations and guides are
adhered to.
Start, operate and maintain the photovoltaic system only in accordance with the following regulations and
standards.
Installation manual
Warning labels and tips on the photovoltaic module
Further applicable documents
System specific regulations and requirements
Valid international, national and regional specifications, especially as pertaining to the installation of electrical
appliances and systems, to working with direct current and to the regulations of the local power company
applicable to parallel operation of solar power system
Regulations of the construction employers’ liability insurance association
Regulations concerning accident prevention
2.3 Personnel Qualifications
The operator and the installer are responsible for engaging only trained and schooled specialists to carry out
installation, maintenance, initial operation and dismounting.
Ensure all personnel have understood this manual and are capable of implementing the instructions.
Ensure all personnel are familiar with and adheres to the pertinent accident prevention and safety regulations.
Ensure all personnel uses appropriate protective clothing and equipment.
2.4 Changes and Alterations
Changes and alterations to the installation system can damage the photovoltaic module or impair its proper
functioning.
Refrain from making changes or reconstructions during the process of installation, excepting for the steps
described in this manual.
2.5 Sources of Danger
The photovoltaic module is a product made of glass and should be handled as such.
Do not place against bare edging.
Do not step on or burden improperly.

2.5.1 Electrical Installation
Ensure that the electrical installation and initial operation is carried out by a licensed electrician.
See that the entire off-circuit voltage is hooked up even by minimal sunshine.
Do not exceed the maximum permissible system voltage of the photovoltaic modules even by low
temperatures.
Electric Arcs on Direct Current Conductors!
Simultaneous contact to both poles causes fatal injury.
Do not sever live cables.
Bare cable ends should be connected or insulated.
Voltage Higher than Safety Extra-Low Voltage (SELV)!
Injury to persons due to summation of voltage during series connection
Observe proper safety and security measures.
Dampness During Electrical Installation!
Injury to persons, damage to the system
Carry out work on the system only on a dry undersurface.
During installation see that photovoltaic modules, wiring, etc., are dry.
2.5.2 Working on the Roof
TIP
Safety regulations state that work higher than 3 meters (eaves height) requires scaffolding with safety nets.
If it is not possible to put up scaffolding or if the roof is very steep:
Put on a safety harness and attach it to a stable structure.
Use a proper safety rail when working on the roof.
Arrange for a suitable work surface for tools and material.
Arrange for cordoned off areas to protect against falling objects.
Heed all relevant regulations for working on a roof.

3.2 Solrif®-framed photovoltaic modules
Solrif®-framed modules consist of standard modules mounted with special Solrif® profile frames and sealed
watertight.
The profile frames of adjoining modules fit neatly together, thus forming the water runoff level of the roof. Along the
sides impermeability between the overlapping module edges is guaranteed by means of an additional rubber lip.
By roof slopes >10° the rainproof integration of the modules into the roofing is thereby possible in accordance with
guidelines set by the German Roofers’ Association (ZVDH).
Ready to mount Solrif®-framed photovoltaic modules for in-roof installation can be obtained by various means:
Solrif®frame kit with framing from Schweizer
Module manufacturers, wholesalers or partners of the Ernst Schweizer AG.
The modules have the following measurements:
Measurement Lamination
measurement L x W
Framed module (mm) (L+50) x (W+32)
Laying measurements
(mm) (L+31) x W
Thickness (mm) Ca. 34
Mass (kg) Lamination + ca. 1.5 -
2.5
Table 3-1: Measurements of the photovoltaic modules
TIP
Please always consult the current data sheets for the exact specifications of framed modules.

3.3 Substructure
The substructure is the basis for the in-roof mounting of the modules. It consists of battens and mounting boards
fastened directly to the roof. It is constructed by means of a grid plan (cf. chapter 4.2.2, p. 26).
3.4 Mounting Clamps
Modules framed with Solrif® XL profile frames are braced to the substructure with mounting clamps. Three different
types of clamps can be used:
Number Designation Article Number
1 Mounting clamp “profile” and “frame”
respectively 13318
1.1 Mounting clamp “profile”, black 06497
2 Mounting clamp “glass” and “module”
respectively 13319
2.1 Mounting clamp “glass”, black 06500
3 Mounting clamp “top”, long, for flat
sheet-metal seams 33954

Mounting Clamp „Profile“
The mounting clamp “profile” is used to brace two modules respectively to their frames in the overlapping area.
This clamp is normally necessary.
Clamp width: 16.5 mm
Material gauge: 1,5 + 2,0 mm
Material: Stainless spring steel type 1.4310
Screw type: Cylinder-head screws 5 x 35 high grade (2
screws)
Image 3-3: Mounting clamp “profile”
Mounting Clamp „Glass“
In order to meet the demands of statics, a module can be additionally fastened in the glass area by means of the
mounting clamp “glass”. The necessary number of clamps per module edge is to be determined on the basis of the
grid plan in accordance with the static demands. To protect the glass the front side of the clamp has been coated
with weatherproof plastic.
TIP
The mounting clamp “glass” has been conceived as an additional measure, dependent upon module size and
static demands, not necessary all the time nor in every case.
Clamp width: 16.5 mm
Material gauge: 1,5 + 2,0 mm
