The Schletter FS Uno for ground mount photovoltaic (PV) installation is specifically designed to meet or exceed applicable IBC and ASCE standards.
Features• Pre-assembled components• Fully integrated and modular components • Wind tunnel tested• Includes grounding module clamps
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. During installation, fully assemble the system before securing bolts to the final torque.

CONCRETE SHALL BE READY MIXED IN ACCORDANCE WITH ASTM C94 AND SHALL BE DESIGNED FOR A MINIMUM 28 DAY COMPRESSIVE STRENGTH AS FOLLOWS: FOUNDATIONS…………………………………………………………3,000 PSI* *DESIGNED FOR 2,500 PSI
• Review final drawing. Drawing will include information vital to the proper installation of the foundation posts such as the embedment depth, post-to-post spacing, and installation tolerances.
• Please note: Schletter does not provide construction layouts.
• For longer racks, intermediate stakes may be required.
• Installation tolerances:
Lateral post placement is ±5.0”
Total Lateral deviation of posts within an array is ±5.0”
Post height variation tolerance ±0.40”
Post verticality tolerance <2.0° in all directions
Post rotational tolerance <±5.0°
Array tilt angular tolerance ±1.0°

Position hydraulic ram and lift post into position beneath ram head
Hammer head touching top string line indicates correct depth is reached
2. Post Installation
• Position each post at respective installation locations based on the completed stake-out (use a forklift).
• Position the hydraulic ram (GAYK) at the installation location and lift the post into position beneath the ram head.
• Level hammer using bubble level on hydraulic ram.
• Level mast of hydraulic ram.
• Level post using a torpedo level.
• Advance the post approximately two feet into the subsurface then re-check level.
• Advance the post to the embedment depth as shown on the final drawing.
• Position string lines: bottom string line is used for correct placement of post; top string line is measured from the top of the post to bottom of the hammer head indicating the correct embedment depth.
• When installing subsequent posts, ram until the hammer head touches the top string line. Use string line as guide to determine
correct placement and depth of posts
Mark each post location using soil nails with flagging
Position posts on marked locations (use a forklift)
Ram two posts at opposite ends of array for string line
Individual Assembly Groups1. Install of Optional Post Splice
2. Attach Steel Head
• Verify torque on all bolts.
• Splices are used to extend the length of a post.
• Splice location will vary depending on project.
• Consult project specific drawings.
• Once the head assembly is aligned, verify the torque of the bolts.
• Head piece attaches to inside right of the post
Feed the M12 bolts through the pre-punched hole in the strut and ti ghten loosely with nut and washer to the steel head
Align steel head to the inner side of the post and fasten using M12 bolts, washers and nuts (front view of post)
Install shim plates between post and splice tubing using 3/4” bolts, nuts, and washers
