Stainless steel Midclamp points, 2 per module,
pierce module frame anodization to bond
module to module through clamp.
Serrated ange nut bonds stainless steel clamp
to stainless steel T-bolt
Serrated T-bolt head penetrates rail anodization
to bond T-bolt, nut, clamp, and modules to
grounded SM rail.

Serrated T-bolt head penetrates rail anodization
to bond T-bolt, nut, and L-foot to grounded
SM rail System ground including racking and
modules may be achieved through the trunk cable
of approved microinverter systems. See page I for
details
WEEB washer dimples pierce anodized rail to
create bond between rail and lug
Solid copper wire connected to lug is routed to
provide nal system ground connection.
NOTE: Ilsco lug can also be used when secured to
the side of the rail. See page J for details

BONDING RAIL SPLICE BAR
Bonding Hardware creates bond between splice
bar and each rail section
Aluminum splice bar spans across rail gap to
create rail to rail bond. Rail on at least one side
of splice will be grounded.
Note: Splice bar and bolted connection are
non-structural. The splice bar function is rail
alignment and bonding.
