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.

Stainless steel self drilling screws drill and tap
into splice bar and rail creating 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.
Serrated ange nut removes L-foot anodization
to bond L-Foot to stainless steel T-bolt
Serrated T-bolt head penetrates rail anodization
to bond T-bolt, nut, and L-foot to grounded SM
rail
Hex nut with captive lock washer bonds metal
microinverter ange to stainless steel T-bolt
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 I-3 for details
