Install Module Clamps
Position and place the Mid Clamps and End Clamps onto the Main Beam at the marked locations. See the spac-
ing info on the previous page.
Use a level to put each Mid and End Clamps in a horizontal position before tightening their U-bolts
Tighten the U-bolt nuts just enough to hold the horizontal position as you will be placing solar modules onto
them in next steps. You will need to move the clamps slightly after you place the solar modules between them so
that the module frames are tight against the vertical stops on the mid clamps.
Start in the center of the Main Beam. Lay the first module onto the flat flanges of the clamp bases.
Center the solar module in the north/south direction to overhang equally past the clamps.
Loosen the next mid clamp and move it against the first solar module so that both clamps are firmly against the
module frame and re-tighten to hold position.
Add modules one at a time and repeat this procedure in both directions.
Place each solar module onto the mid clamp base and center the module to
overhang equally past the clamps.
Install Mid Clamp tops with the 1/4 x 2.5-inch hex bolts, flat & lock washers
after the mid clamps have been moved thight against the module frames.
Be sure that the bolt holes in the top part of each clamp lines up with the
threaded hole in the bottom part of the clamp. It is a good idea to use
antisieze compound on these bolts. Start the bolts by hand far enough to be
sure they are not cross-threaded and torque to 84 inch-lbs (7 ft-Lbs). TO AVOID DAMAGE TO THE BOLT
AND FASTENER, DO NOT OVERTIGHTEN. The flanges on the top part of the clamp will pull downward on
the top of the module frames when the bolts are tightened.
