SYSTEM CERTIFICATION
24
The Ecofoot5D system has been certifi ed 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 fi re resistance testing.
In conducting these tests, specifi c modules are selected for their physical properties so that the certifi cations can be broadly applied. The following lists the specifi c
modules that were tested and the applicability of those certifi cations to other modules that might come onto the market. PV modules may have a reduced mechani-
cal load rating, independent of the Ecofoot5D load rating. Please consult the PV module manufacturer's installation guide for more information.
In addition to UL 2703 certifi cation, Unirac performs internal testing beyond the requirements of certifi cation 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:
• Frame thicknesses greater than or equal to 1.0 mm.
•
Basic single and double wall frame profi les (some complex frame profi les could require further analysis to determine applicability).
•
Clear and dark anodized aluminum frames.
•
All installation confi gurations have achieved a minimum of 5psf design load in the downslope direction, tested with the Q Cells Q.PEAK DUO
XL-G11.3/BFG module listed in this table
