Safety and Installation Manual
3.0 Safety Instructions
3.1 Handling Safety
➢ Always use protective wear according to your local regulations and to best industry pratices.
➢ Always use the original product packing. Repacking modules using different methods and materials may lead to
module damage or breakage.
➢ The module pallet labels contain information regarding the maximum number of modules which can be stacked,
and the number of stackable pallets. Follow them strictly. Contact your distributor for further information.
➢ PV modules are vulnerable to breakage. Handle them with appropriate care.
➢ Do not damage or scratch the PV module surfaces. Especially do not apply paint or adhesive to the surfaces.
➢ Do not use the junction boxes or cables as a grip.
➢ Do not use a single frame as module grip. Always hold the modules with both hands each grabbing a frame
part.
➢ PV modules with broken glass cannot be repaired and must not be used. Broken glass could cause injury.
Contact with any part of broken PV modules can result in lethal shock. Broken or damaged PV modules must
be handled carefully and disposed of properly.
➢ Do not walk on the module neither use it as a support holder for people, animals or tools. The module may
only be used for the functions it has being designed
➢ Ensure that PV modules are only subjected to ambient temperatures in the range of -30 °C to + 45 °C.
3.2 Installation Safety
➢ When exposed to light (even under low light conditions), PV modules produce almost full voltage. Current and
power increase with light intensity.
➢ Under operating conditions, a PV module is likely to produce more current and/or voltage than reported at
Standard Test Conditions (1000 W/m2, AM 1.5 and 25 °C cell temperature). Accordingly, the values of short-
circuit current (Isc) and open-circuit voltage (Voc) given on the module label should be multiplied by a factor
of 1.25 when determining component voltage ratings, conductor current rating, fuse sizes, and size of controls
connected to the PV output.
➢ Do not install when there are strong or gusty winds, frosted roof surfaces or wet conditions. Do not install or
handle the modules when they are wet.
➢ Before installation visually inspect the module for transportation damages. Never install or expose to sunlight a
module with damaged junction box where live terminals are exposed or accessible.
➢ When installing PV modules above ground follow all applicable safety requirements to avoid possible falling or
other safety hazards.
➢ Open Renewables® PV modules can only be switched off by removing them entirely from light or by fully
covering their front surface with an opaque material. When working with PV modules in light, follow all
applicable regulations regarding working with live electrical equipment. Do not touch electrically live parts
while the PV module is exposed to light.
➢ Fasten the cables to the mounting structure but avoid any mechanical stress on them. Ensure that connectors
are clean and dry before connecting.
➢ Never disconnect electrical connections under load, because direct current can arc across gaps.
➢ Do not wear metallic jewellery while performing installation.
➢ There are no user serviceable parts within the module. Do not attempt to repair any part of the module.

4.0 Preparation for operation
4.1 Storage
➢ For transportation of Open Renewables® modules shall be on the original product packing.
➢ Store the products within the storage conditions limits.
➢ Secure modules against falling and scratching.
4.2 Unpacking
➢ Please read, understand and follow the unpacking instructions, on this manual.
➢ Notice that the packing instructions may change without prior notice, therefore you should consult Open
Renewables® website or request your distributor for the latest version.
5.0 Mechanical Installation
➢ Install the PV modules under a tilt angle of min. 15 degrees in order to allow any dirt being washed away from
rain.
➢ Use support structures specialized for PV applications and designed for local maximum wind and snow loads.
Ensure the PV modules are not subjected beyond the specified wind or snow loads.
➢ Ensure PV modules are not subjected to excessive forces resulting from thermal expansions of the support
structure.
➢ The support structure must not cause any bending or twisting of the PV module.
➢ The distance between the rear module surface and the roof shall be at least 100 mm to allow for proper
cooling. A minimum clearance between PV modules of at least 1.0 cm is required to allow for thermal
expansion of the PV frames.
➢ Keep the rear surface of the PV modules free from any objects which could come into contact with the module,
particularly under mechanical load.
➢ Do not drill any holes on the frames. Modules equipped with 3rd generation frames do not have any pre-drilled
holes. Customers requiring pre-drilled holes should order them in advance.

Safety and Installation Manual
Open enewable PV modules supports two different mounting methods:
5.1 Method “A”
➢ Method “A” is only applicable to modules equipped with 1st and 2nd generation frames. Please consult drawing 4
or contact your sales representative to determine which frame equips your module.
➢ Modules shall be mounted using 4 holes located on the rear side of the long frame parts. Use 4 M6 stainless
steel bolts per PV module, with nuts, washers and lock washers see drawing 1).
5.2 Method “B”
➢ The selected mounting structure shall be sufficiently-dimensioned, load-bearing and permanently corrosion-
resistant.
➢ The solar module must be aligned in such way to avoid any total or partial shadowing of the module, even
temporary. Shadowing may lead to damage the solar modules, failure of the PV generator and loss of output.
➢ The modules must be attached to the substructure without tension and deformation at no less than four points,
and the clamp surface per attachment point on the module must be at least 750 mm².
➢ The centreline of the clamps should be centred with the area marked as per drawing 3. Some models have a
pre-printed mark on the frame, for easier mounting.
➢ Follow the mounting instructions of the substructure manufacturer. Use appropriate tools and ensure the torque
is within the manufacturer specified range for the module fixing clamps and other screw connections.
➢ The additional loads which arise by way of the weight and the structural attachment of the PV system are to be
included in the structural analysis of the overall construction.
➢ Attachment with clamps on the narrow sides of the solar module may not be performed.
➢ Attach the solar modules so that they with-stand all foreseeable loads and weather-induced influences.
➢ The substructure and the solar module must have the same heat-expansion coefficient as the aluminum frame.
Contact corrosion between the solar module and the substructure is to be avoided when different materials are
used. Lightning protection is recommended according to local regulations.
➢ The solar module may not stand in tail water or condensation water.

6.0 Electrical Installation
➢ PV modules of different size and/or electrical configurations must not be used in the same system.
➢ Open Renewables® PV modules are factory-equipped with cables and connectors for easy interconnect in series.
➢ Cover all modules in the PV array with an opaque cloth or material before making or breaking electrical
connections.
➢ Open Renewables® recommends that all wiring be double insulated with a minimum temperature rating of
110°C. All wiring should use flexible copper (Cu) conductors. The minimum size should be determined by the
applicable codes. We recommend a size not less than 4mm2. The insulation type should be appropriate for the
type of installation method used and must meet SKII (Safety Class II) and IEC 61730 requirements."
➢ Match the polarities of cables and terminals when making the connections; failure to do so may result in
damage to the PV module.
➢ Ensure that all electrical connections are secure and tight.
➢ A bypass-diode is integrated in one of the 2 PV module junction boxes. This diode is not user-replaceable. The
junction box must not be opened in the field. Doing so will void the warranty.
➢ When connecting module in series be aware the module voltages will be summed. The maximum number of PV
modules being connected in series must be calculated in line with the applicable regulations in such a way that
the specified maximum system voltage of the PV module and all other electrical DC components will not be
exceeded in open-circuit operation.
➢ Not more than 2 PV modules or module strings shall be connected in parallel without using series fuses rated at
20 Ampere minimum.
➢ PV modules with a suspected electrical problem should be returned to Open Renewables® for inspection and
subsequent actions as described in the Open Renewables® LIMITED WARRANTY FOR PV-MODULE(S).
6.1 Safety-related grounding of module frames
➢ Open Renewables® strongly recommends grounding of PV module frames even when applicable regulations,
code requirements and standards do not require any safety-related grounding. On 1st and 2nd generation frames
the long frame rails are provided with holes should be used for grounding purposes only and in accordance
with the local regulations, code requirements and standards, as per drawing 4, bellow. On the 3rd generation
the any of the corner pieces can be used to connect the module to ground using a self tapping screw, ST 4.8
with a length between 6 and 16mm.

7.0 Operation
➢ Before connecting a PV system to the grid the entire system must be checked and tested according to the
applicable regulations for low voltage electrical systems and for grid-connected power generators.
➢ Depending on local utility policies the connection to the grid and start-up of the PV system may only be
performed by an authorized installer.
8.0 Maintenance
➢ Open Renewables® PV modules do not require any routine maintenance. However, Open Renewables®
recommends that PV systems are checked periodically - at least once a year - and any significant changes are
reported immediately. Pay special attention to loose or corroded mechanical and electrical connections.
➢ The performance of the PV modules might be affected by dust, dirt or other deposits on the surface. In this case
Open Renewables® recommends cleaning the surface of the modules with cold water and a sponge. Do not use
harsh cleaning materials such as scouring powder, steel wool, scrapers, blades or other sharp instruments to
clean the glass surface of the module. Use of such materials will void the product warranty.
9.0 Decommissioning and Disposal
