BeforeInstallation,Please
ReviewtheFollowingChecklist
● Ensure that SolaRack® is compliant with your module
manufacturer.
● Ensure compliance with any clearances required by
your local fire department of building & safety code.
● Ensure your work complies with naonal, tate and
local requirements - Even those that may supersede
this manual.
● All installaons mu t be preformed by licensed
contractors & electricians that are bonded and
insured.
● Only use system components supplied by SolaRack®
● Make sure your roof is in proper condion prior o
installaon. Do not in tall on damaged roofs!
● Use only appropriate, recommended tools and wear
safety goggles and gloves during installaon

Please follow this instruction graphic when solar modules
are mounted in portrait alignment. Rail must be mounted

requirements rail placement that differs from these
instructions, please check with your module manufacture
for compliance regarding mounting requirements.
Rail must not exceed 24” cantilever

The SolaRack® Comp Kit is optimally spaced based on local city code and the rail system used.
For measurements related to clearances and roof setbacks, please refer to your local building and safety office or other
authorities having jurisdiction. When using the Comp Kit with SolaRack® Rails, attachments may be spaced
up to 72”. For proper installation, please refer to the detailed installation guide on page 11. Lag screw must be
installed in the center of a roof rafter and sealant must be applied under the flashing during installation. Installation must be
preformed by licensed professionals to avoid roof damage. Removing stone gravels and deforming shingles in any way
during installation can and will shorten the lifespan of the roofing. Be sure not to install systems on poor quality or damaged
surfaces.

UL Requirement & Guidelines
Page 12
CONFORMSTOULSTD1703
SolaRack® racking systems have been tested and listed by ETL for system fire
classification Class A type 1& 2. Testing was preformed and passed at 5” above
the roof, allowing installation without limitation of distance between the roof and
solar modules. System assembly to be mounted over a fire resistant roof covering
rated for application. Re-inspect the installation for loose components, loose
fasteners and any corrosion. If found, the affected components are to be replaced
immediately.
CONFORMSTOULSTD2703
SolaRack® system components were evaluated assuming a 20 Amp maximum
series fuse size. SolaRack® mid & end clamps bond and ground the system by
penetrating the anodized surface of thesolar module with our stainless steel
pointed pins. (Fig 1,2) The system is grounded to the rails by stainless steel
channel nut. At the end of every array, an ILSCO SGB-4 ground lug must be used
for grounding (Fig 3), ILSCO SGB-4 acceptable wire size is 4-14 SOL-STR and is
suitable for use with either copper or aluminum wire,The size of grounding wire
will be determined by electrical code. The SolaRack® splice kit was tested as a
grounding & bonding method and is also listed under UL 2703 (Fig 4). SolaRack®
does not require jumpers! Periodic inspection is required. Re-inspect installation
for loose components, loose fasteners and any corrosion, such that if found the
affected components are te be replaced immediately.
Important
All bare copper must be separated from any aluminum surface.
Check with your local AHJ regarding roof setbacks or any special requirements.
Some jurisdiction’s require visible labels to easily identify UL listed systems.
Please read carefully and follow the following guidelines and standards set by UL to comply with the ETL certification
issued. SolaRack® is certified by ETL for the following listing: UL STD 1703 Fire Rating & UL STD 2703 Grounding
and Bonding. The components evaluated for grounding and bonding that has passed received the UL STD 2703 by
ETL are as follow:
- SolaRack® Integrated Grounding & Bonding Series SR-UMGM Under Module Universal Mid Clamp
both in clear anodized and black electrophoresis.
- SolaRack® Integrated Grounding & Bonding Series SR-UMGE Under Module Universal End Clamp
both in clear anodized and black electrophoresis.
- SolaRack® Integrated Grounding & Bonding Series SR-ECO, SR-STRD, SR-HD Splice Kit’s
both in clear anodized and black electrophoresis.
- SolaRack® Integrated Grounding & Bonding Series IGB-SR-MICRO Micro Attachment Bolt
