2 Mounting InstructionS G-MX G-Max Ground Mount System The Schletter G-Max 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 Includes grounding module clamps The G-Max is capable of accommodating nearly any framed PV module in portrait orientation. Each G-Max is custom designed to meet specific structural load requirements. Included in G-Max are clamps specifically designed to secure and bond frame of a PV module. In turn, the components and assemblies that comprise G-Max 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 system before securing bolts to the final torque.⁵ The following is a guide to properly install a G-Max in order to meet design and test standards. 6 6 Key omponents. Post. Strut*. Girder*. Head*. Purlin 6. Module clamp Pre-assembled girder assembly *Strut, girder, and head make-up pre-assembled girder assembly The G-Max is evaluated for electrical bonding only. G-Max meets all I and SE requirements for structural loading; it was not evaluated for loading under UL 70. G-Max 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 mounting system may be used to ground and/or mount a PV module complying with UL70 only when specific module has been evaluated for grounding and/or mounting in compliance with included manual. Project drawings supersede installation instructions; see project drawings for all measurements, torques, and tolerances. 6 Installer is responsible for verifying that system meets applicable NE and S standards. / 6 Schletter Inc.

Refer to project drawing for tolerances for: Embedment depth (Figure 6) Support distance (Figure 7) Lateral cantilever (Figure 7) Post height variation (Figure 8) Post verticality (Figure 9) Post rotation (Figure 0) For longer racks, intermediate stakes may be required. Posts are installed vertically. For East-West slopes greater than.7 (0% slope) (Figure ), contact your Schletter representative to discuss custom rack options. Racks can be designed for slopes up to 0 (8% slope).

6 Mounting InstructionS G-MX. Post Installation Position each post at respective installation locations based on completed stake-out. dvance post to embedment depth as shown on final drawing. Position string lines: bottom string line is used for correct placement of post; top string line indicates correct embedment depth: string is run from top of first post to top of first post of adjacent rack. When installing subsequent posts, ram until hammer head touches top string line. Upon completion of post pile drive, check that each post meets appropriate tolerances. If posts do not fall within tolerances, contact your Schletter representative. Notes: If post splice is required, see Splice onnection section for splice installation instructions. If after ramming post, there are signs of cracking, use 9% zinc paint to touch up post. Mark each post location using soil nails with flagging Position posts on marked locations X Ram two posts at opposite ends of array for string line Use string line as guide to determine correct placement and depth of posts Position hydraulic ram and lift post into position beneath ram head Hammer head touching top string line indicates correct depth is reached 6 /6 Schletter Inc.

7 G-MX Mounting InstructionS Mounting Individual ssembly Groups. Mount Girder ssembly Girder, strut, and head are pre-assembled for ease of installation and adjustability to ensure that specified tilt angle and clearance tolerances are maintained. Install location bolts (shown as and ); hand tighten to allow for installation of girder assembly. Position strut onto previously installed lower location bolt. Position head onto upper location bolt Pivot girder until head and post align. Secure girder assembly in place by installing bolt at upper post. hole location (shown as ). heck angle of girder and ground clearance; refer to construction drawings for measurement. Ground clearance is a reference dimension only and can be affected by adjustment to rack. See project drawings. Tighten post bolts using 9 mm socket.

14 Mounting InstructionS G-MX Equipment Grounding Many 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. 8 Only use appropriate 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 ). The installer of Schletter s electrically bonded G-Max must provide components necessary for the final connections to grounding electrode system. Typically 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 installer 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. Installer shall be fully responsible for all connections between Schletter s bonded G-Max 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: connection area is sufficiently sized dissimilar metals are not in direct contact connection does not interfere with other components connection is protected from damage alculation for overcurrent protection device including but not limited to spacing and wire size is the responsibility of installer. 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. Maintenance should only be performed by qualified personnel. heck mechanical details of 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 intended tightening torque. heck is successful if bolt cannot be loosened. If >0% of checked bolted connections are loose, check has to be increased to 0% of all bolted connections. If more than 0% of connections are still loose, all bolted connections much be checked. Tighten all non-conforming bolts to specified torques Requirements per SME 07 and IS WRNING: Risk of death by electric shock. VERTISSEMENT: anger de mort par secousse électrique. Safety Precautions Follow proper installation and safety procedures at all times. Edges of parts may be sharp. Follow proper lifting procedures. For More Information For United States, visit or call or for anada, visit or call to speak to a Schletter representative for more information. 8 Schletter recommends two bonding jumpers to connect separate systems for redundancy.
