2-ROW ELEVATED
SYSTEM CERTIFICATION

MECHANICAL LOAD TEST
The SM Ascender system has been certified and listed to the UL 2703 standard (Rack Mounting Systems and Clamping Devices for Flat-Plate Photovoltaic Modules
and Panels). This standard includes electrical grounding, electrical bonding, mechanical load and fire resistance testing.
In conducting these tests, specific modules are selected for their physical properties so that the certifications can be broadly applied. The following lists the specific
modules that were tested and the applicability of those certifications to other modules that might come onto the market. PV modules may have a reduced mechani-
cal load rating, independent of the SM Ascender load rating. Please consult the PV module manufacturer's installation guide for more information.
In addition to UL 2703 certification, Unirac performs internal testing beyond the requirements of certification tests in order to establish system functional limits,
allowable loads, and factors of safety. These tests include functional system tests, and destructive load testing.
Mechanical Load Test Modules
The modules selected for UL 2703 mechanical load testing were
selected to represent the broadest range possible for modules on the market.
The tests performed cover the following basic module parameters:
•
PV module may have reduced load rating, independent of the SM Ascender
rating. Please consult the PV module manufacturer's installation guide for
more information.
•
Frame thicknesses greater than or equal to 1.0 mm.
•
Basic single and double wall frame profiles (some complex frame profiles
could require further analysis to determine applicability).
•
Clear and dark anodized aluminum frames.
