Bonding with QClick Technology° <br /> As shown in Image 2.4.4 and 2.4.5, the QRail Clamps with QClick <br /> Technology and rails are designed with complementary, sharp hooks. <br /> When the clamp is installed in the rail and the bolt is tightened, the bolt - <br /> forces the hooks into the rail. Then, as the clamp engages the module <br /> and the bolt is tightened to the recommended torque specification n°°ksft <br /> [12 ft-lbf (16 N-m)], these hooks are pulled into the QClick channel <br /> and penetrate the aluminum oxide or painted coating on the rail and <br /> electrically bond to the rail, clamp, and bolt. A star washer under the bolt Image 2.4.4 Image 2.4.5 <br /> head serves to electrically bond the bolt to the body of the mid or end Clamp hooks Clamp hooks and rail <br /> clamp, thus forming a secure electrical bonding path as shown in Image <br /> 2.4.6. <br /> PV Module Bonding <br /> PV module frames are electrically bonded to the QRail system by the bonding mid clamps. <br /> Bonding plate mid clamps are preassembled with a stainless steel plate below the clamp head. <br /> The stainless steel bonding plate is formed with spikes that pierce the oxide of the clamp head <br /> and the PV module, forming an electrical bond between the module, the clamp head, and thus Image 2.4.6 <br /> to the rest of the QRail system. Bonding mid clamps are available in either mill or black finish. Clamp bonding path <br /> Universal height end clamps are available with optional bonding <br /> clips (WEEB-BMC-11). Bonding versions of the end clamps <br /> are useful when mounting a single module or in shared rail <br /> configuration where bonding mid clamps are not utilized. The <br /> WEEB-BMC-1 works in the same way as the bonding plate. <br /> Image 2.4.7 Image 2.4.8 <br /> Bonding plate mid clamp Fixed end clamp <br /> NOTE! <br /> The installer is responsible for and shall provide an appropriate W <br /> method of direct-to-earth grounding according to the latest <br /> edition of the National Electrical Code, including NEC 250: <br /> Grounding and Bonding and NEC 690: Solar Photovoltaic <br /> Systems. <br /> The QRail Hidden End Clamp is NOT a bonding solution and <br /> therefore cannot be used on single modules. It must always be <br /> installed in conjunction with at least one Bonding Mid Clamp. <br /> Image 2.4.9 Image 2.4.10-1 <br /> Universal end clamp Universal end clamp <br /> w/WEEB-BMC <br /> 'WEEB-BMC-1 is evaluated as an alternative component and maybe used interchangeably with a WEEB-BMC Bonding Clip. <br /> B1 7.2.3-46 9 Jul-2019, Rev 4.2 <br />
