4 General safety instructions Ensure you observe the general safety fitting and maintenance prescriptions. If you need any clarifications, please call immediately our customer service at number Fitting and commissioning of the systems must be carried out exclusively by skilled personnel who, thanks to their specific training or professional experience, are able to ensure that the work is performed correctly and to high standards. 2.The existing structures on which the system is to be fitted must be checked to ensure that the loading capacity of the building/structures is adequate. 3.Observe all regulations and local and national building regulations, and provisions relating to the environment. 4.Observe all regulations and national laws and local regulations regarding health and safety, accident prevention and the requirements of professional associations. In particular, it is necessary: Wear personal protective equipment: safety helmet, safety gloves, safety shoes, etc. If the system is to be fitted on an elevated surface comply with safety regulations for work at heights by using safety harnesses, falling objects signs, etc. At least two people must be on the work site during the fitting procedures, so that one person can provide first aid or call emergency services in case of accident. 5.Efficient grounding system is essential. If necessary, use the lightening protection devices. 6.You can not cut the mounting rails. In the event that Thesan S.p.a. Technical Dept. requires to cut the profiles, depending on the specific project to be carried out, you must make sure to remove the burrson the surfaces affected by the cut in order to eliminateany possible risk of injury. Also you need to make surethat the cutted rails are not curvy. 7.The electrical installation must be carried out exclusively by skilled personnel who, thanks to their specific training or professional experience, are able to ensure that the work is performed correctly and to high standards. The wiring of the photovoltaic modules must be made to avoid the possible creation of loops. General safety instructions 3

5 Universal Light system with locking brackets, for sloped roof FEATURES OF THE SYSTEM Thanks to the significant reduction in the number of components, Thesan Mounting System allows a reduction of approximately 57% in the amount of time required to fit the photovoltaic modules, compared to similar mounting systems of key competitors. Robustness, practicality, and reliability over time are key characteristics of the system. Suitable for photovoltaic modules with and without frame. Thesan is leader in guaranteeing, on request, a reliable and efficient after-sales service, which is at customers disposal for any requirements. All Thesan Mounting System documents are available at: For any need or clarification you may required, please contact our customer service: tel ufficio.tecnico@thesan.com The Universal Light system with locking brackets, for sloped roof, is a not pre-assembled mounting system for photovoltaic modules. In order to ensure safe and proper fitting of the system, each step described in these instructions must be carefully and accurately followed. At each step, necessary materials and equipment are listed. For any inconvenience or misunderstandings please call immediately our customer service.

10 Assembly instructions Step 1 Preliminary checks a. Check the design measurements on the roof on which the system is to be fitted. b. Provide a minimum distance of the rails from the edge of the roof of 500 mm. This system is highly versatile, hence it is ideal for installation on different types of roofs and surfaces, such as: - Corrugated sheet metal roofs; - Wooden porch roofs; - Metal porch roofs; - Pitched roofs with counter batten Step 2 Alignment a Use the line marker cord to trace the positions where to apply the adhesive and structural tape. The distance will be determined by Thesan Technical Dept. (or Thesan configurator software) depending on the specific project to be carried out. In case of different assembly solutions the warranty is void. Step 3 Applying the adhesive and structural tapes a. Make sure that the metal surface where the tapes are to be applied is clean. If there are traces of dirt, remove any residual particles with a rag soaked in an oil-free cleaner. b. Cut the tape into lengths of approx. 10 cm. c. Remove the protective film from the tape and apply the latter, with a slight pressure, to the support surface. Assembly instructions 9

11 Step 4 Positioning the Universal Light mounting rails a. Remove the protective fi lm from the upper side of structural adhesive tape, previously applied on the corrugated metal sheet. b. Position the Universal Light mounting rail aligned with the tape, taking into account the trace previously made with the line marker cord in order to ensure correct alignment of the rails. c. Place a couple of brackets, one on the left side and one on the right side of the rail, close to the previously applied tapes. d. Fasten the brackets to the support surface. Use suitable fasteners depending on the support surface: - Wood surfaces use stainless steel torx drive self- drilling screws, fl at head - Metal surface use galvanized steel hex head self- drilling screws - Concrete surfaces use concrete wall plugs The type of fastener will be determined by Thesan Technical Dept. (or Thesan confi gurator software) depending on the specifi c project to be carried out. e. Space each profi le from the next by at least 1 cm in order to allow a safety margin in the case of thermalexpansion. Step 5 Positioning and fixing the photovoltaic modules If the clamps you are using are not preassembled, insert the hammer head screw in the specific opening in the upper side of the mounting rail, turn the screw of 90 clockwise, position the clamp and partially tighten the nut with safety fit. Upper side Bottom side Attention: Follow the instructions of the manufacturer of the PV modules. b. If the PV module is mounted landscape, the long side of the clamp must be in longitudinal position respect the mounting rail, if instead the PV module is mounted portrait, the long side of the clamp must be in orthogonal position respect the mounting rail. c. Position the photovoltaic module and fully tighten the nut with safety fit to a torque of 14Nm. d. Ensure the correct position of the clamp compared to the frame of PV module. The vertical walls of the clamp must adhere perfectly to the frame of the module: a. If pre-assembled clamp sets are used, insert the hammer head screw into the specific opening in the upper side of the mounting rail, press the clamp gently to turn the screw of 90 clockwise. Make sure that hammer head screw is in an orthogonal position respect to the rail, and that the spring of the clamp makes completely adhere the hammer head screw to the rail.

12 Step 6 Grounding system a. Efficient grounding system is essential. b. Fastened with a screw the ground wire at any point on the aluminium rail, using only stainless steel fasteners and components. c. Tighten the screw securely. Assembly instructions 11
