RATINGS UL 2703 LISTED #5003225 #5017912 Conforms to STD UL 2703 (2015) Standard for Safety First Edition: Mounting Systems, Mounting Devices, Clamping/ Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels • Max Overcurrent Protective Device (OCPD) Rating: 40A • Max Module Size: 30.
CHECKLIST PRE-INSTALLATION IRONRIDGE COMPONENTS ☐ Verify module compatibility. See Page 14 for info. ☐ Purchase 2” or 3” Pipe or Mechanical Tubing Pipe: 2” or 3” (NPS) ASTM A53 Grade B SCH 40 Pipe, galvanized to a min of ASTM A653 G90 or ASTM A123 G35. Mechanical Tubing: 2.375” x 12 ga (O.D) or 3.500” x 8 ga (O.D.) Mechanical Tubing with one of the following Galvinizations (ASTM A1057).

1. BUILD Build BASE Base (CONT.) GROUND SCREW FOUNDATIONS Follow respective Ground Screw Manufacturer’s installation methods for driving screws into soil. Insert vertical piers into ground screws, ensuring at least 22” of pier is inserted into ground screw. Tested and/or Evaluated Ground Screws 2” System Manufacturer Model # Set Screw Torque Specification 3” System American Ground Screw Model 3 76mm x 3(+)mm American Ground Screw Model 3 102mm x 3.
3. Place Rails A. ATTACH HARDWARE A On the ground, attach Rail Connector brackets to rail by sliding 3/8”-16 bonding bolts into side slot. Space out to match vertical pier spacing. With brackets in place, finger tighten Flange Nuts onto bolts. ➢ Tape ends of rail, to keep bolts from sliding out while moving. B. FASTEN CONNECTORS Center Rails on horizontal beams, leaving equal distance on ends. Secure with Rail Connector hardware: 3/8”-16 U-bolts, Flange Nuts, Flat Washers and Lock Washers.
5. SECURE MODULES A. SECURE FIRST END A UFO 80 in-lbs Place first module in position on rails, a minimum of 1” from rail ends. Snap Stopper Sleeves onto UFO. Fasten module to rail using the UFO, ensuring that the UFO is hooked over the top of the module. Torque to 80 in-lbs. ➢ Ensure rails are square before placing modules. ➢ Hold Stopper Sleeves on end while torquing to prevent rotation. ➢ If using CAMO instead of UFO + Stopper Sleeve, refer to Page 7 for CAMO installation procedure. B.
CAMO A. SLIDE INTO RAIL A Slide CAMO into rail channel far enough to clear the module frame. CAMO requires 6" of clearance from end of rail. B. PLACE MODULE 6" Cle ara nc e B Place module on rails (module cells not shown for clarity). When installing CAMO the module can overhang the rail no more than 1/4”. C. PULL TOWARDS END C Pull CAMO towards rail ends, at 45 degree angle, so the bonding bolt contacts the module flange edge. D.

DIAGONAL BRACES (OPTIONAL) Slide sleeve on north pier 2-3” above the ground (6” max). Attach Diagonal Brace to sleeve with 1/2” hardware. Slide second sleeve up on south pier 2-3” below top cap (6” max). Raise Diagonal Brace to align holes in sleeve and brace. Attach hardware and raise sleeve to full extent. Torque Diagonal Brace bolts to 40 ft-lbs. Torque set screws to 15 ft-lbs.
SPLICING CROSS PIPE The following instructions should be followed, when required, to join more than one section of horizontal beam together to ensure bonding is maintained throughout the system. A Horizontal Beam Horizontal Cross Beam Beam A. MECHANICAL TUBING SPLICES Mechanical tube splices shown in the table below shall be of equivalent Allied Flo-Coat, Allied Gatorshield or Wheatland ThunderCoat coating. Mechanical Tube Size of the Structure Splice Tube Size 2.375” OD, 12 Gauge 2.
MICROINVERTER KITS Use IronRidge's Microinverter Kit to bond compatible microinverters and power optimizers to the racking system. Insert Microinverter Kit T-bolt into top rail slot. Place compatible microinverter or power optimizer into position and tighten hex nut to 80 in-lbs.
DiagonalUSING SYSTEMS Braces MICROSTORAGE (Optional) PRODUCTS Use IronRidge's Microinverter Kit to bond compatible microstroage devices to the racking system. Insert Microinverter Kit T-bolt into top rail slot. Place compatible microstorage into position and tighten hex nut to 80 in-lbs. COMPATIBLE PRODUCTS Microinverter Kit (80 in-lbs) PHAZR PHAZR Devices PHAZR-X, where X is 6-12. ➢ Running a separate equipment grounding conductor to the PHAZRs is not required.
MODULE COMPATIBILITY The Ground Mount System may be used to ground and/or mount a PV module complying with UL 2703 only when the specific module has been evaluated for grounding and/or mounting in compliance with the included instructions. Unless otherwise noted, “xxx” refers to the module power rating and both black and silver frames are included in the certification.
