DISCLAIMER
This manual describes the proper installation procedures and provides necessary standards required for product reliability
and warranty. All installers must thoroughly read this manual and have a clear understanding of the installation steps and
procedures prior to installation. Failure to follow these guidelines may result in property damage, bodily injury or even
death.
IT IS THE INSTALLER’S RESPONSIBILITY TO:
• Ensure that the installation is completed by a licensed solar professional.
• Comply with all applicable local or national building codes, including any that may supersede this manual.
• Ensure all products are appropriate for the installation, environment, and array under the site’s loading conditions.
• Use only IronRidge parts or parts recommended by IronRidge; substituting parts may void any applicable warranty.
• Review the Design Assistant, Engineering Design Guide, and Certication Letters to conrm design specications.
• Comply with all applicable re codes including, but not limited to, keeping walkways clear and avoiding obstacles.
• Ensure provided information is accurate. Issues resulting from inaccurate information are the installer’s responsibility.
• Conrm with the module manufacturer that Ground Mount is compatible with the selected module.
• Validate foundation parameters prior to installation, as a local geotechnical report may be required to assess ground
conditions. We recommend consulting with a local engineer familiar with local regulations and build site requirements,
including soil conditions, terrain and load criteria. All parameters may impact foundation requirements.
• Ensure safe installation of all electrical aspects of the array. All electrical installation and procedures should be
conducted by a licensed and bonded electrician or solar contractor. All work must comply with national, state and local
installation procedures, product and safety standards.

1. BUILD BASE
A. POSITION PIERS
Establish pier locations. Once grid of pier positions has
been set, verify all angles are square.
☑Spacing varies with load conditions. Consult engineering specs.
B. STAND POSTS
Excavate foundation, insert vertical posts, and install
concrete piers. Make sure vertical posts are plumb, level,
and square, in parallel rows, evening tops with level.
☑For concrete piers, brace posts until cured to remain plumb.
☑In some cases, cross bracing is required to provide extra support
for posts. If required, install Diagonal Braces at this time.
A. MOUNT TOP CAPS
Mount a Top Cap on each post. Wait to tighten set screws.
☑If using Diagonal Braces, install them prior to Top Caps.
B. LAY PIPES
Set cross pipes in Top Cap grooves. Attach with 3/8”-
16 U-bolts, ange nuts, at washers, and lock washers.
Torque U-bolts to 180 in-lbs. Complete and align entire
assembly. Torque Top Cap set screws to 240 in-lbs.

3. PLACE RAILS
A. ATTACH HARDWARE
On ground, attach Rail Connector bracket to rail by sliding
3/8”-16 bolts into side slot. Space out to match pier
spacing. With bracket in place, nger tighten ange nuts
onto bolts. Repeat for remaining Rail Connectors.
☑If using Mid Clamps with hex bolts, slide provided 1/4”-20 bolts
into top slot of rails at this time. Space bolts for panel spacing.
☑Tape ends of rail, to keep bolts from sliding out while moving.
B. FASTEN CONNECTORS
Center rails on cross pipes, leaving equal distance on
ends. Secure with Rail Connector hardware: 3/8”-16
U-bolts, ange nuts, at washers, and lock washers.
Torque U-bolt to 60 in-lbs and bracket to 204 in-lbs.
☑Spacing between rails should align with module mounting holes.
WEEB LUGS
Review Wiley WEEB Installation Instructions, using 6-10
AWG (minimum) solid copper grounding wire. Torque hex
nut to 120 in-lbs and set screw to 84 in-lbs.

5. CLAMP MODULES
A. END CLAMPS
Place rst module in position on rails, a minimum of 1.5”
from rail ends. Secure End Clamps on rails, ensuring they
are hooked over top of module. Torque to 84 in-lbs.
B. MID CLAMPS
Slide Mid Clamp T-bolts in top rail slots, placing them ush
against opposite side of module. Place second module
into position on rails, against Mid Clamp bolts. Put a Mid
Clamp, then ange nut, on each bolt. Torque to 120 in-lbs.
Repeat for each following module.
☑Refer to WEEB Installation Manual for installing WEEB Clips.
☑If using Under Clamps or Wire Clips, refer to Page 6.
☑Grounding Mid Clamps should not be used with Ground Mount.
C. END CLAMPS
Place last module in position on the rails, a minimum of
1.5” from rail ends. Secure End Clamps on rails, ensuring
they are hooked over top of module. Torque to 84 in-lbs.
D. REPEAT STEPS
Clamp remaining module rows.
☑If using End Caps, refer to Page 6.

pests from collecting inside rail.
Firmly press End Cap onto rail end.
Wire Clips offer a simple wire management solution.
Firmly press Wire Clip into top rail slot. Open clip and
insert electrical wire accordingly. Close clip once complete.
