1 Mounting InstructionS FS UNO FS Uno The Schletter FS Uno solar mounting system for ground mount photovoltaic (PV) installation is specifically designed to meet or exceed applicable I, SE, and UL standards. Features onforms to UL 70 ertified to UL/OR Std 70 Electrically bonded unit 0 mp series fuse rating Pre-assembled components Fully integrated and modular components Wind tunnel tested Includes grounding module clamps The FS Uno is capable of accommodating nearly any framed PV module in portrait or landscape orientation. Each FS Uno is custom designed to meet specific structural load requirements. Included in the FS Uno are clamps specifically designed to secure and bond the frame of a PV module. In turn, the components and assemblies that comprise an FS Uno form an electrically bonded unit. While individual components and structural sections will vary between designs, the primary assemblies and installation methods will remain the same. uring installation, fully assemble the system before securing bolts to the final torque. The following is a guide to properly install an FS Uno in order to meet design and test standards. 7 6 Key omponents. Post. Steel head. Strut. -Rail (girder). Retainer plate 6. Z-Rail (purlin) 7. RapidK TM module clamp I00 The FS Uno is evaluated for electrical bonding only. The FS Uno meets all I and SE requirements for structural loading; it was not evaluated for loading under UL 70. FS Uno is not to be used in corrosive atmospheres. Maximum number of modules shall not exceed maximum system voltage ³ Individual parts and components will vary from system-to-system. Please reference system specific drawings. This racking system may be used to ground and/or mount a PV module complying with UL70 only when the specific module has been evaluated for grounding and/or mounting in compliance with the included manual. Installer is responsible for verifying that system meets applicable NE and S standards. Schletter Inc. Updated 0/07 V Subject to change without notice /

Equipment Grounding Many PV installations contain more than one mounting system. Such cases call for electrically bonding each of the different manufacturers systems. Since individual racks are fully bonded units it is only necessary to connect individual racks together from one single point to another single point. 6 Only use stainless steel hardware when connecting harnesses or jumpers to the mounting system. Take care to prevent copper wires from directly contacting aluminum surfaces as this will cause corrosion. For this purpose, Schletter offers a bonding jumper (see page 9). The PV INSTLLER of Schletter s electrically bonded FS Uno must provide the components necessary for the final connections to the grounding electrode system. Typically the installation will incorporate a grounding electrode (ground rod), appropriately sized copper wire, rated wire connectors, and grounding lugs which are rated for this purpose. The PV INSTLLER must follow all manufacturers installation literature. Installation must comply with all applicable NE/S sections including but not limited to; NE 0 (Grounding and onding), NE 690 (Solar Photovoltaic Systems), S. (Safety Standard for Electrical Installations), and all other applicable state, and local electrical code requirements. PV INSTLLER shall be fully responsible for all connections between Schletter s bonded FS Uno and PV grounding electrode system. Equipment grounding conductors shall be no less than WG (copper) or WG (aluminum). Equipment grounding conductors can be connected to any exposed metallic portion of rack system provided that: a. connection area is sufficiently sized b. dissimilar metals are not in direct contact c. connection does not interfere with other components d. connection is protected from damage alculation for overcurrent protection device including but not limited to spacing and wire size is the responsibility of the installer. 6 Schletter recommends two bonding jumpers to connect separate systems for redundancy. / Schletter Inc.

13 FS UNO Mounting InstructionS Maintenance Yearly inspection of system should be conducted to maintain optimal performance. Visually inspect for signs of damage, wear, corrosion, or movement. Replace any affected components immediately. heck for loose wiring heck mechanical details of the structure: -t least % of bolted connections must be checked using a calibrated torque wrench. The torque wrench must have a display or be a click type torque wrench. -Torque wrench should be set at 0% of the intended tightening torque. heck is successful if the bolt cannot be loosened. -If >0% of the checked bolted connections are loose, the check has to be increased by a factor of five. -If more than 0% of connections are still loose, all bolted connections much be checked. -Tighten to specified torques Requirements per SME 07 and IS WRNING: Risk of death by electric shock Maintenance should only be performed by qualified personnel. Safety Precautions Follow proper installation and safety procedures at all times. Edges of parts may be sharp. Follow proper lifting procedures.
