6.3 Installing the End Modules The end modules of the PV system are fastened on the outer side with two module end clamps each. Three types of module end clamps are available from Quick Mount PV. Fixed end clamps are sized to fit a particular module thickness and will not work on modules of other thicknesses. Hidden end clamps will work on any module with a flange in the acceptable clamping zone. Universal end clamps are designed to fit 2 ranges of module thicknesses. Universal end clamps are available in the following size ranges: ■ 30-45mm -`•��- ■ 38-50mm ---` Mounting Steps, Fixed Height End Clamps: ■ Place and align an outside module. The QRail must extend beyond Image 6.3.1 the module frame by a minimum of 1.2 in. ■ Insert the QClick of the end clamp into the channel of the QRail. ■ Push the module end clamp flush to the module frame. -=== ■ Tighten the bolt to 8 ft-Lb (11 Nm), thus clamping the module. Mounting steps, Universal End Clamps: ■ Place and align an outside module. The QRail must extend beyond the module frame by 1.2 in. (30 mm). Image 6.3.2 ■ Insert the QClick of the end clamp flush against the module frame. The lip of the upper clamp body should be flush against the edge of the module. ■ Ensure that the lower section of the clamp body sits squarely on the top of the rail. ■ While holding the upper clamp body against the module and 1 2 3 the lower clamp body, tighten the clamp bolt to 8 ft-lbf (11 N-m). m age 6.3.3 End Clamp installation Material damage due to incorrect installation Incorrectly mounted clamps with QClick Technology can slip out. PV modules can fall and be damaged. Mount all clamp connections in accordance with the instructions. • ■ Make sure the clamps are installed correctly. DANGER ' Ensure the module is installed flush and tight against the side of the end clamp. ■ Ensure proper torque of the end clamp mounting bolt 8 ft-lbf(11 N-m) or 9ft-lbf for hidden end clamps.
