Polar Bear III 10 Degree Installation Manual

Appendix B: UL 2703 Grounding 

PanelClaw components within the array are required to be electrically bonded to other DC grounding 
paths via the use of either #8 or #6 AWG Cu bonding jumpers and a UL 467 listed Tyco solid wire 
grounding assembly, part number 2106831, manufactured by Tyco Electronics Corporation. The ground 
path follows through the Tyco lug, Ballast Tray, Support, Claw and into the module frame. The module 
frame’s anodization is broken via the through-bolt connection at the module mounting holes, which is 
secured with a serrated flange nut. The bonding continues through the module frame to the adjacent 
Claws as shown below.
