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’s racking system. 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 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. If loose
components or loose fasteners are found during periodic inspection, re-tighten immediately. If
corrosion is found, replace affected components immediately.
•Installer to ensure the structural support members 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.
•Installer is responsible for and shall provide an appropriate method of direct-to-earth grounding
according to the latest edition of the National Electrical Code, including NEC 250: Grounding and
Bonding, NEC 690: Solar Photovoltaic Systems, and CSA C22.2, Safety Standard for Electrical
Installations, Canadian Electrical Code, Part 1.
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 roof system is responsible for reading these instructions and determining the safest way
to install the roof 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. Provide required safety railing, netting, or safety lines
for crew members working on the roof.

SunModo Racking Self-Bonding System
SunModo’s SMR system meets the stringent requirements of UL 2703 and CSA C22.2 No. 61730-2
which covers rack mounting systems, mounting grounding/bonding components, and
clamping/retention devices for photovoltaic (PV) modules. The SMR system is intended for, but not
limited to, PV module installations on residential roof tops, commercial buildings and freestanding
ground mount structures.
The SMR system components are designed in accordance with the National Electrical Code,
ANSI/NFPA 70 and Model Building Codes. These code requirements cover rack mounting systems
and clamping devices intended for use with PV module systems with a maximum system voltage of
1500V.
The patented SMR self-bonding system is for use with PV modules that have a maximum series fuse
rating of 30A. This means the maximum number of PV modules in the SMR system is limited by the
system voltage, so if a system has multiple inverters, the SunModo racking system can theoretically go
on forever.

Torque Values
These values must be adhered to, both for mechanical strength and to insure the performance
of the integral grounding and bonding features. It is required that a torque wrench be used to
measure the bolt torque during final assembly, and it is recommended that anti-seize
compound be applied to the screw threads.
