Installation and Maintenance Instructions for Multisol P6-60, M6-60 Photovoltaic Modules Application class A in accordance with EN 61730
Multisol modules are quality products produced us
ing high quality solar cells made of crystalline silicon. All materials used have been carefully selected. That is why Multisol modules have an especially long life cycle. It is important that the information provided below is observed. These instructions should be read carefully and observed fully before installation, initial operation and during maintenance of photovoltaic systems that use Multisol PV modules.
Danger! Risk of death or serious injury if not observed! It is crucial therefore that any work performed on PV systems is carried out exclusively by skilled professionals who have the respective training. 1. Module mounting When installing Multisol photovoltaic modules, local building regulations and the relevant generally accepted rules of technology must be adhered to at all times. The rules as per DIN 1055 or EN 1991 apply for structural safety. The applicable latest version of regional standards and regulations should be adhered to respectively. For this reason, installation of the modules should only be planned and implemented by skilled professionals with respective training. Distributed loads from wind, snow and tare weight will affect the modules. These will be carried by the glass of the laminate and the module integrated frame made of aluminium profiles. For this purpose, the solar modules must be mounted to a stable substructure using a suitable mounting system. A minimum distance between Modules of 5 mm is recommended. The mounting holes found in the long frame segments can be used (for their position see fig. ll Mounting holes). M6 sized bolts with approx. 10 Nm torque should be used. Alternatively, clamps can be used for the connection. In this case, clamp supplier’s users manual has to be followed. When using clamps, they can be attached at the position where the frame holes are found. The dimensions of the clamp surfaces should be sized adequately. (We recommend surfaces of 500 mm?).

I. Mounting the modules
II. Mounting holes
Mounting methods deviating from fig. I, fig. II or appendix II need approval from Scheuten Solar. Forces impacting the frame profile at the points of contact must not result in any deformation of the frame. Constraint between frame and glass should be avoided at all costs. If installed on an incline, the modules should be secured from sliding. Suitable fasteners should not be attached any further away than around 100 mm from the frame’s edges. Drainage openings must not be covered up. All attachment means must be made of noncorrosive material. When designing PV systems using Multisol standard modules, no changes may be made to original design as was delivered. For example, no additional holes should be drilled into the unit for mounting purposes, for potential equalisation or for any other purposes. Any changes of this kind will void the unit’s warranty.
Additional information: Fasteners and mounting systems are not included in the scope of delivery of Multisol standard modules. The conditions of use as provided by the respective manufacturer of such elements and systems are to be observed. Multisol photovoltaic modules are not considered as regulated building products (in the meaning of e.g. DIBT=Deutsches Institut für Bautechnik; German Institute for Building Technology). Local building codes and regulations must be followed at all times, such as in case of the use of Multisol PV modules as overhead glazing or rooftop systems, where an adequate fire protection must be taken care of. To rule out extreme temperatures and damage as a result, PV modules may not be subject to any artificially concentrated sunlight. Instead, it should be assured that there is enough ventilation from behind.
The applicable regulations pertaining to work safety, accident prevention and securing the construction site must be observed. Persons and objects have to be secured against falling. Any third party need to be protected against injuries and damages.
Do not step on the modules. 2. Electrical installation The solar modules are designed to be used in PV systems of application class A and can therefore be operated in systems using hazardous direct current and power (with ratings higher than 120 V DC in accordance with EN 61730). PV modules in this application class may be used in systems that are accessible without restrictions. Multisol modules that are certified within this application class in accordance with EN 61730 satisfy the requirements of safety class II if installed in accordance with instructions.
Danger! Risk of death or serious injury from electric shock! Despite protection against accidental contact, under unfavourable conditions if several modules are connected in series, hazardous voltage of several hundred volts may be present when exposed to light. For this reason, work on the modules may only be performed by qualified skilled professionals. The manufacturer’s instructions of the other components being used, especially those of the inverter, are to be observed.
After unpacking the modules, inspect them carefully for any damage. Inspect in particular all plastic parts, which are critical to assure proper reinforced or dual insulation. PV modules may not be lifted at the connection cables or the junction box.
Danger! Risk of death or serious injury from electric arcs! Exposed to light, under load and especially in the event of a short circuit, high levels of direct current can result in dangerous electric arcs, if, for example, the connection between two PV modules is separated. When integrated into a grid connected system, instructions of your local grid operator have to be followed. 2.1. Junction box The junction box is of protection class IP 67. Within it are the module-integrated bypass diodes. Observe the details listed on the cover. The box cover may only be opened in exceptional cases by a skilled electrician authorized by the module manufacturer. 2.2. Connection cables and plug-in connectors The integrated connection cables are dual insulated and UV resistant. The wire diameter of the connection cables is 4 mm?. For wiring, the connection cables have preassembled plugin connectors with reverse polarity protection. Because of its safe design features, accidental contact with current-carrying cables can be ruled out entirely when used correctly. When connected, protection class IP 68 applies. The connectors may only be plugged in when dry. Special attention should be given to assure a seamless connection. In general, the connection cable should not be subject to any tensile loads. Wires should be attached to the mounting system using UV resistant cable ties to avoid chafe marks from movements or tensile loads. 2.3. Module interconnection Module voltage adds up as a result of a series connection, module current adds up as a result of a parallel connection. Applicable regulations should be observed to assure safety when working with electrical devices. The maximum system voltage noted in the appendix, on the data sheet and on the type label must not be exceeded, not even at especially low temperatures. Depending on its set-up location and environmental conditions, a PV module may supply higher voltages and / or higher current when compared to standard testing conditions. For this reason, in order to define the rated voltage values of components, rated current values of wires, the size of fuses and the design of control systems that are to be connected at the output of PV modules, the Isc and Voc values listed on the module and in the data sheet should be multiplied by 1,25. Depending on the installation location, special protection may need to be taken against lightning and electrical surge. Tight parallel wiring of the plus and minus lines can reduce coupling of interference currents.
2.4. Grounding When grounding the module frame, only use the grounding holes provided, which are marked accordingly (see Ill. Grounding). The mounting systems may not be used for grounding. Grounding may only be performed by a qualified electrician. During maintenance and repair work to the module, grounding may not be interrupted or destroyed.

3. Maintenance Generally speaking, solar modules are maintenance free. For smaller inclination angles, it may be necessary to clean the modules with plenty of clean water. Avoid any harsh additives. When cleaning the glass, typical cleaning tools may be used. Any dried dirt residue should not be scratched or scraped off using sharp tools. Otherwise, scratches or microcracks may cause damage to the glass surface. Every once in a while, the modules should be inspected to assure they are in proper condition, correctly wired and mounted. While doing so, assure that they are still firmly attached and that there is no corrosion. 4. Exclusion of liability
