Tighten Mid Clamp U-Bolts
As each module clamp is positioned tight against module frames,
thighten the U-Bolt nuts through the square access holes on the top
of the top clamps. Torque the U-Bolts nuts to 20 ft-lbs.
End Clamp Installation
Install an End Clamp at both ends of the mount, tightening the
U-bolts just enough to hold them in a horizontal position. Leave an extra 1/4" of space, more than the PV
module width, between the End Clamp and the Mid Clamp to allow for easy insertion of the module.
Starting at one end of the array, place an end PV module tight up against the last Mid Clamp, and rest the other
side of the PV module on the bottom tabs of the End Clamp to hold it up.
Loosen the End Clamp U-Bolts if necessary and move it to fit firmly against the solar module frame and re-
tighten to hold position.
Attach Panel Frame Clamps to the end clamp base with the 5/16-18 x 7/8 bolt flange nut and washer as shown,
torque to 12ft Lbs. NOTE: The Panel Frame Clamp must be resting on the inside of the solar module frame with
bolts against the solar module frame.
Tighten the U-Bolt nuts on the End clamps to 20 Ft-lbs. There are slots in the End Clamp base to use for the
module clamp. Choose two of the slots that place the frame clamp closest to the mounting hole in the solar
module frame. We provide two possible positions for the module clamps because some modules have cross
braces that interfere with placing the clamp.
