Please read carefully before installing
Product is tested to and recognized to UL 2703 standards for safety grounding and
bonding equipment.
SunModo PV Rack Mount System can be used to mount photovoltaic (PV) panels in
a wide variety of locations. All installations shall be in accordance with NEC
requirements in the USA. The self-bonding system is for use with PV modules that
have a maximum series fuse rating of 30A. Mechanical design loads per UL 2703:
Downward Pressure: 33.42 psf (1600.2 Pa), Upward Pressure: 22.28 psf (1066.8
Pa), Down-Slope: 5 psf (239.4 Pa).

Installer Responsibility
Before ordering and installing materials, all system layout dimensions should be confirmed by field
measurements. SunModo reserves the right to alter, without notice, any details, proposals or plans. Any
inquiries that you may have concerning installation of the PV system should be directed to your SunModo
Sales representative. Consult SunModo Sales for any information not contained in this manual. This manual
is intended to be used as a guide when installing SunModo EZ Tilt-Up systems. It is the responsibility of the
installer to ensure the safe installation of this product as outline herein.
Installer shall employ only SunModo products detail herein. The use of non SunModo components
can void the warranty and cancel the letters of UL compliance.
Installer shall guarantee that screws and anchors have adequate pullout strength and shear
capacities.
Installer shall adhere to the torque values specified in this Instruction Manual.
Installer shall use anti-seize compound, such as Permatex anti-seize, lubricant is recommended for
all threaded parts.
Installer is responsible to install solar panels over a Fire Resistant roof covering rated for the
application.
Installer is responsible to determine that the roof, its rafters, connections, and other architectural
support components can sustain the array under all code level loading conditions.
Installer shall adhere to all relevant local or national building codes. This takes account of those that
supplant this document’s requirements.
Installer shall guarantee the safe placement of all electrical details of the PV array.
Installer shall comply with all applicable local, state and national building codes, including periodic
re-inspection of the installation for loose components, loose fasteners and any corrosion, such that
if found, the affected components are to be immediately replaced.
Installer to ensure the structural support members or footings for mounting the array can withstand
all code loading conditions. Consult with licensed professional engineer for the appropriate loading
conditions.
Installer to follow all regional safety requirements during installation.
This racking system may be used to ground and/or mount a PV module complying with UL 1703
only when the specific module has been evaluated for grounding and/or mounting in compliance
with the included instructions.
Installer shall ensure bare copper grounding wire does not contact aluminum and zinc-plated steel
components to prevent risk of galvanic corrosion.
If loose components or loose fasteners are found during periodic inspection, re-tighten immediately.
If corrosion is found, replace affected components immediately.
Safety
Review relevant OSHA and other safety standards before following these instructions. The installation of
solar PV systems is a dangerous procedure and should be supervised by trained and experienced
personnel.
It is not possible for SunModo to be aware of all the possible job site situations that could cause an unsafe
condition to exist. The installer of the ground system is responsible for reading these instructions and
determining the safest way to install the ground system. These instructions are provided only as a guide to
show a knowledgeable, trained erector the correct part placement one to another. If following any of the
installation steps would endanger a worker, the erector should stop work and decide upon a corrective action.

SunModo Self-Bonding System
SunModo developed a proprietary grounding and bonding system that is built into the mounting
hardware for the rails, clamps and splices. We provide further grounding through all of the SunBeam
racking components including the Pipe Caps, Beams, Posts and Post Base Plates. All hardware meet
UL 2703 Grounding and Fire Standards tested by ETL.
The basis of the system is our patented stainless steel floating grounding pin which is designed to be
captive in the mounting components and provides a bonding path from the PV panel frames to the rails
and rail splices, and finally to the ground lug. The self-grounding and bonding system is for use with
PV modules that have a maximum series fuse rating of 30A. The maximum number of PV modules is
limited by the system voltage, so in a system has multiple inverters, the SunModo racking system can
theoretically go on forever.
Finally we have added a spring and Blue 242 Loctite to our Mid Clamp assemblies. The sprig keeps
the Mid Clamp in the open position ready to receive the solar module. The Blue Loctite is a light
bonding agent allowing the T-Bolt engagement into the Rail when the Collar Nut is turned from above.
The Blue Loctite has the added benefit of being an anti-seize agent for stainless steel hardware in the
area where it is applied. For additional anti-seize protection refer to the ‘Tools Required for
Installation’ section of this document.
Mid Clamp with Ground Pins
Similarly, the rail splices the grounding pins, eliminating the need for extra bonding components.
