Appendix A: Grounding & Bonding
The EcoFoot5D system has been tested by TüV Rheinland and conforms to UL 2703 for Grounding and
Bonding when installed per the published installation instructions.
EcoFoot5D carries module-to-module ground bond through the Wind Deflector and Mid-Support – Items 5 and
Items 7 & 8 respectively, listed in the “EcoFoot5D Core Components” table in this document.
Each row of modules/wind deflectors in an array of up to 400 modules must be grounded per the NEC and
ANSI/NFPA 70 either through the designated ground hole in the Wind Deflector, or by drilling a ¼” ground hole
into the Wind Deflector a minimum of ½” from any edge. One Ground Lug is required for every 400 modules
connected within an array.
Ecolibrium Solar recommends using #6 copper ground wire in conjunction with WEEB grounding devices such
as the WEEB-LUG-6.7 or WEEB DSK516. Lugs are a single use component.
Other grounding methods must be reviewed and approved by a licensed master electrician or electrical
engineer and Authority Having Jurisdiction (AHJ).
Green lines represent ground bond path.
Wind Deflectors carry module-to-module
east/west ground bond. Mid-Supports carry
row-to-row north/south ground bond.
