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.

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
