3.7 Electrical Grounding
Every module must be electrically bonded. The FX system makes bonding simple through
integrated bonding.
• One Grounding Lug is required per continuous array.
• The Grounding Lug attaches easily to any Bridge along the north edge of the array.
• Each Bridge provides east-west bonding, but only along the south (down-slope) side.
o FX can be installed without Trim, in which case the Bridges on the southern edge
of the array can be turned around to provide east-west bonding.
• Each Mount provides north-south bonding
Bonding Example
In the arrays shown below, no Bridges are required between the right column and the center
column for structural reasons. BUT, at least one Bridge is required for bonding.
Right column is NOT BONDED
