This install guide officially documents the components used and proper methods for an EcoFoot5D installation.
Bonding elements are incorporated into EcoFoot5D 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:
EcoFoot5D 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.
Seismic and Uplift Design Requirements:
EcoFoot5D can be attached when required by seismic and uplift
conditions as specified by the Authority Having Jurisdiction (AHJ). Addendums in this install guide document
the components used and proper methods for an EcoFoot5D installation with attachments. Use the method
required for the specific Fire Code Rating of the PV module.
Re-Inspection:
Ecolibrium Solar 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 EcoFoot5D ballasted racking system. A list of compatible modules may be found in “EcoFoot5D Install
Guide Appendix - Compatible Modules.pdf” on our website: www.ecolibriumsolar.com
UL2703 Qualification:
In cases where UL 2703 certification is required, the EcoFoot5D system conforms to the
UL2703 Standard for grounding and bonding and fire ratings. The EcoFoot5D 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.
EcoFoot5D 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. When installing Type
2 modules a Ballast Tray is required. For roofs with lower fire ratings, the existing rating is maintained when
EcoFoot5D is used.
At this time, the EcoFoot5D system is undergoing further testing pertaining to mechanical loading with specific
modules. Further information about Ecolibrium Solar’s UL2703 conformance may be found in “EcoFoot5D
Install Guide Appendix - UL2703 Qualification.pdf” on our website: 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
