6 | 11Fire Rating

UL1703 - S Dome Fire Rating:

The S Dome system has undergone fire performance testing per UL 1703 Section 15, Fire Performance.

A System Class A fire rating is achieved when using CrossRail under the following conditions:¬ Used in combination with a UL 1703 Listed module with a fire performance of Type 1 or Type 2. Consult the module manufacturer

for specific fire performance rating information.¬ Type 1 modules tested with UL

- Use of Fire Guards required on East and West edge of arrays to be compliant with UL 1703 for Type 1 modules.- The use of the Fire Guard on a UL 2703 system will not affect the UL 2703 system listing.

¬ Type 2 modules tested with Western Fire Center¬ Roof slope of 2/12 inch rise per linear foot or lower.¬ The assembly is to be mounted over a fire resistant roof covering rated for the application.¬ The results of the racking system do not improve a roof covering Class rating.

UL2703 - S Dome Bonding:

The S Dome system has obtained a UL 2703 system listing from Underwriter's Laboratories (UL).

A sample bonding path diagram is shown in Figure 1, below. Specific installations may vary based on site conditions and AHJ requirements.

Each electrical connection has been evaluated to a maximum fuse rating of 30A. When installed per these installation instructions, all connections meet the requirements of NEC 690.43.

Installation should be periodically reinspected for loose components or fasteners and any corrosion.

Everest S Dome system was tested with the SolarWorld, Sunmodule family of modules.¬ PlusSW200-300Mono (including black)¬ PlusSW200-280Poly (including black)

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.
