Bonding and Grounding
Appropriate means of bonding and grounding are required by regulation. The information provided in this manual shall
always be verified with local and national building codes.
K2 Systems has obtained a UL 2703 system listing from Underwriter’s Laboratories (UL).
A sample bonding path diagram is shown in Figure 1 below. Your specific installation may vary, based upon site conditions
and your AHJ‘s requirements.
Each electrical connection has been evaluated to a maximum fuse rating of 30A. At least one ground lug per row of
modules must be used to ground all strings within each sub-array, although additional may be used for redundancy. When
installed per these installation instructions, all connections meet the requirements of NEC 690.43.
This racking system may be used to ground and/or mount a PV module complying with UL 1703 only when the specific
module has been evaluated for grounding and/or mounting in compliance with the included instructions.
