Roof Slope Range: 0-7 degrees maximum, 3-degree limit for unattached seismic.
Wind Zone: EcoFoot2+ is designed to mount photovoltaic modules on flat roof surfaces with a maximum pitch of 7
degrees in areas with extreme wind conditions. Please contact Ecolibrium Solar for clarification or assistance.
Installation Requirements: EcoFoot2+ is ballasted photovoltaic racking designed as a system which requires all
EcoFoot2+ components, the specific module, and ballast placement prescribed in the PE stamped design. The
absence of any of these elements in any given sub-array could present a compromised condition on the roof. Arrays
shall not be left unattended in such a state during an installation.
This install guide officially documents the components used and proper methods for an EcoFoot2+ installation.
Bonding elements are incorporated into EcoFoot2+ components. As the system is built on the roof, components and
modules are bonded together. Specific steps to ensure a bonded system are described through the installation guide.
It is the installer’s responsibility to ensure that the system is safely and properly installed, and that the system is
bonded back to a final ground point.
When wiring the array, keep bare copper from contacting bare aluminum.
Thermal and Seismic Design Requirements: EcoFoot2+ is a flexible and expandable design that accommodates
various array geometries.
Maximum widths for arrays are as follows:
• 60-cell modules, 26 modules in a row
• 72-cell modules, 22 modules in a row
Minimum spacing between sub-arrays is 6”. Site specifics may further limit array sizes and spacing.
Re-Inspection: Ecolibrium recommends periodic re-inspection of the installation for loose components, loose
fasteners, and any corrosion, such that if found, the affected components are to be immediately replaced.
Compatible Modules: Ecolibrium Solar has evaluated many photovoltaic modules for installation compatibility with
the EcoFoot 2+ 10-degree racking system. A list of compatible modules may be found in “EcoFoot2+ Install Guide
Appendix - Compatible Modules.pdf” on our website: www.ecolibriumsolar.com
UL2703 Qualification: In cases where UL 2703 certification is required, the EcoFoot2+ system conforms to the
UL2703 Standard for grounding and bonding and fire ratings. The EcoFoot2+ system may be used to ground and/or
mount a PV module complying with UL1703 only when the specific module has been evaluated for grounding and /or
mounting in compliance with the included instructions.
EcoFoot2+ Racking maintains a Class A fire rating when installed in landscape orientation according to the installation
instructions, on a low slope roof Class A roof with Type 1 and Type 2 modules.
Further information about Ecolibrium Solar’s UL2703 Listing, including module load ratings may be found in
“EcoFoot2+ Install Guide Appendix - UL2703 Qualification.pdf” at www.ecolibriumsolar.com

UL2703 System Label: The label shown below is stamped into to the Wind Deflector (identified as component 5 in
the installation guide).
The Date Code ABCYZZ shown above will appear on production parts, letters defined as follows:
• ABC shall be an acronym for identifying the source factory
• Y shall be the Quarter of the year (i.e. 1, 2, 3, 4) of manufacture
• ZZ shall be the last 2 digits of the year of manufacture
