2 Safety instructions The system must be built exclusively with the ballast specified in the structural analysis for superimposed loads. You will receive these from Schletter along with the plant design. Alternatively, the data can be obtained directly in the "Download" area on our website: Risk of breakage! PV modules can be damaged if stepped upon. The planning, mounting and commissioning of a solar energy plant must be undertaken, exclusively, by qualified personnel. Unprofessional execution of the project can result in damage to the plant and place people in danger. Risk of electric shock! The mounting and maintenance of the PV modules must be carried out by qualified specialists only. Please observe the safety regulations issued by the PV module manufacturer! Risk of falling! There is a risk of falling when working on the roof as well as when ascending and descending the building. Accident prevention regulations must be observed and appropriate safety equipment must be used. Risk of injury! Objects falling from the roof can cause injury to people. The danger area around the installation site must be sealed off and people close to this area must be warned. Mounting information Make sure that the sealing of the flat roof and the rubber underlays are compatible. If the roof of the roof sealing is very uneven, compensatory measures may have to be taken in order to safeguard an evenly distributed load transfer. The required distances to the roof edges must be maintained. The maximum size of array depends on the type of roof. On membrane roofs, the maximum permissible size of array normally is 0 m, on concrete roofs up to 0 m. On roofs with substrate covering or gravel, it has to be safeguarded that the contact area between the continuous beams and the subsurface is sufficiently skid-proof. AluGrid is not recommended for roofs with a pitch of more than 0 degrees. For reasons of structural safety, at least two module rows should be interconnected. If this is not possible, please consult our technical advisers. The distributed load must not exceed the excess load-bearing capacity of the building! The partial pressure on the surfaces under the continuous beams on the roof cladding must not exceed the admissible distributed surface load.

3 Extending the continuous beams Continuous beams can be extended if required. Insert an AluGrid connector into two rails and fasten it with two self-drilling screws to each rail end. Tools: Power screwdriver with 8 mm bit Mounting of the rubber underlays Press the rubber underlay into the underside of the profile profile (rail). Alternatively: Strips of the surface protection mat are to be laid under the profiled continuous beams that have been designed for this purpose. If the rain water runs at right angle to the continuous beam, short surface protection mat strips are to be laid at certain distances so that the rain water can drain off. The specific distance between these protection mat strips is determined on the basis of the local amount of precipitation. Alignment of the continuous beams After the continuous beams have been equipped with rubber underlays, they are arranged parallel to each other and vertically to the planned module rows. Distance between the beams: Module length plus 0 mm (± 5mm) Anti-skid device On inclined roofs, module arrays must be secured against sliding by a) horizontal fastening or b) coupling two opposite continuous beams using a tension connector at the ridge. For this purpose, fasten the connector to both beams from above with four screws each. Roof parapets can also serve to prevent sliding. A correct fastening and structural safety are compulsory.

4 Mounting of the AluGrid+ clamps Appropriate shade distances and / or row distances must be observed. Let the fastening clamps snap into the profiles at the respective points - see the dimensional drawing on page 5 Mounting of the module-bearing profiles Hook the module-bearing profiles into the AluGrid+ fastening clamps at the front and let them snap in downwards to the rear. Align the profiles at the edge with a small projection and arrange the profiles in the interior area centrally as shown in the picture at the bottom of this page.

6 Mounting of the module-bearing supports. Position the first module bearing support at the edge with its solid support facing inwards. Place the fastening clamp into the cut-out of the metal sheet (left side from the rear) and let it snap into the continuous beam below. Mounting of the module-bearing profiles Slot the module-bearing profile onto the metal lobe of the support. Slot the T-handle onto the metal lobe and hold it firmly - do not turn the T-handle! Turn the profile by 90. The lateral cut-out is used for the edge profiles (turn the long side inwards), in the interior zone, the central cut-out is used. Arrangement: To optimize the load distribution, arrange the inner module bearings as shown in the picture on the right. The bearings along the edge must be positioned with their solid support sides facing inwards. Option AluGrid Protect: Preferably, the mounting of AluGrid Protect is carried out before the ballast is put on. 6

7 Ballast loads Fill the ballast trays as specified in the structural analysis for superimposed loads. We will send you the structural analysis for superimposed loads together with the plant design or it can be obtained directly in the download area on our website: Distribute the ballast evenly into the ballast trays. If the ballast loads are unevenly distributed, place them close to the continuous beams. (Ballast is not included in the scope of delivery for the AluGrid system). Increased loading If heavier ballasts are required for structural reasons, for example in corner zones, additional load trays are to be attached. They can be fastened under the modules. Arrange the ballast trays as required Overlap the metal sheets as shown in the picture on the right. Fit the end plate into the last cut-out. Place the fastening clamps into the lateral cut-outs of the metal sheet and let it snap into the continuous beam below. Maximum permissible ballast per tray: 00 kg Cabling between the module rows Fasten the plastic clips for the cable covering to the continuous beam. Lay in the cables. Cut the cover to size. Thread in the covering at the bottom, then snap it in at the top. Hook in the earthing (grounding) clamp at the continuous beam and clip it onto the cable covering. The cable covering cannot be laid over the module rows without interruptions. max. 0.5 m 7

8 Prepare the cabling of the module Place the cable clips into the designated slots of the bearing supports. Module mounting Position the lower edge of the module on the module-bearing profiles (rails) Connect the module cables as required. Press the cables into the clips. Position the upper edge of the module on the module-bearing profiles. Preparation of the AluGrid pliers Set the AluGrid pliers using the setting screw according to the size of the modules. Make sure that the jaws are movable! Please make sure that the clamp slightly reaches over the edge that is to be clamped when the pliers are strained. Due to tool wear, production tolerances of the module frames, etc., a readjustment may be required. If the clamp does not fit tightly enough, this will have a bad effect on the clamping and thus has to be absolutely avoided

9 5 Fastening of the modules Span the module clamps using the AluGrid pliers. Press the module fittingly onto the bearing. Hook the module clamp into the bearing - first at the bottom and then at the top. Clamp the module clamp onto the module frame by releasing the pliers. Fasten each module with two clamps at the bottom and two at the top. 6 Fastening of further modules Fasten the remaining modules in the same way (Item -5).
