Appendix A: UL 2703 Grounding
The clawFR Dual Tilt 10 Degree flat roof
system may be used to ground and/or mount
a PV module complying with ANSI/UL 1703
or ANSI/UL 61730 only when the specific
module has been evaluated for grounding
and/or mounting in compliance with the
included instructions. For a list of modules
which have been evaluated see
PanelClaw’s
“
clawFR UL 2703 List of Ratings and
Compatible Modules and
MLPEs”
. The most
recent version is available on the PanelClaw
website (
).
System Ground Path
The system ground path
“grid”
is established throughout the array by the interconnection of system components. Specifically, in the column
direction via the Base and Module Connector connections and in the row direction via the Rail connections. A Tyco lug connected to the Rail
establishes a point of connection for the EGC at one location with a contiguous array. All modules are grounded to the system through their
Cam to Module connection.
Note:
The presence of a PV module does not affect the bonding ability of the clawFR system components. More precisely, the grid provides
a means to ground PV Modules which have been evaluated for ANSI/UL 2703 grounding with clawFR.
