Universal Top-of-Pole Mount 6 Modules (UTPM6) Module Type G Assembly Instructions step-by-step assembly and installation Version 1, Rev B SP3331-3 PCN 120516-2
Universal Top-of-Pole Mount For 6 Modules (UTPM6) For Module Type G WARNING Follow the procedures and precautions in these instructions carefully. About the product Periodic Inspection The UTPM6 for module Type G is designed for a wide range of Module size, from 37-42” in width to 61-67” in length. The Universal Topof-Pole support structure mounts on 6 inch SCH40/80 galvanized steel pipe (installer supplied).
UTPM6 Type G Main Components Strongback Module Rails Support Bar Mounting Sleeve Double Hole Slide Plate Cross-Bars Single Hole Slide Plate There are seven main components and attaching hardware.
Universally adjustable to accommodate a range of PV Module sizes E-W adjustability of Module Rails along Cross-Bars. N-S adjustability of Single & Double Hole Slide Plates along Module Rails.

1 Calculate Site Specific Dimensions NOTE When selecting mounting holes, make certain that the hole diameters accept 1/4” hardware as it will be used to secure the PV Modules to the system. The dimensions must be taken from the site-specific Modules. The dimensions will be used to calculate the Module Rail positions. 2 Calculate and Mark the Rail Positions on Cross-Bars Use the worksheet on the next page to calculate Rail positions on the Cross-Bars.
2 6 Calculate and Mark the Rail Positions on Cross-Bars (continued) Assembly Instructions, UTPM6 Type G (Version 2, Rev A)
3 Mark the Cross-Bars NOTE Use precision when measuring and marking the Rail positions on the Cross-Bars. Measure and mark the center of the Cross-Bars then use the calculated dimensions I and O from the previous page to mark off their respective Rail positions. The image below shows these marks and their relationship to the Cross-Bars and Rails after assembly.
4 Calculate and Mark Slide Plate Positions on Module Rails Use this worksheet to calculate the eight Double Hole Slide Plate positions on the Rails. Enter dimensions “H” from Step 1 and complete the calculations. The results define positions “K” to be measured and marked on the four Rails for the eight Double Hole Slide Plates.
4 Calculate and Mark Slide Plate Positions on Module Rails (continued) NOTE Use precision when measuring and marking the Double Hole Slide Plate positions on the Module Rails. Locate the center of the Rails and mark as shown above. These marks correspond to the “K” dimension representing the locations for the eight Double Slide Plates (two-per Rail). The remaining Slide Plates do not require marks as they will be aligned to the Module mounting holes as the Modules are installed.
6 Attach Double Hole Slide Plates to Rails On each of the four Rails, install the two Double Hole Slide Plates to be centered over the previously made marks on the Rails. Insert the head of the Hex Bolt into the Rail channel as shown and align their centers over the marks. Tighten these four Slide Plates securely and torque at 32-34 ft.-lbs. 7 Attach Single Hole Slide Plates to Rails Install the two Single Hole Slide Plates in a similar manner, loosely positioning them as shown above.
8 Install the Mounting Sleeve on Vertical Pipe N Slip the Mounting Sleeve on top of the Mounting Pole allowing it to slide down and bottom out on the Pole. Rotate the Mounting Sleeve so that the Support Bar 9 Pivot Tab is pointing north and the Strongback Vertical Towers are leaning south. Tighten Set Bolts and torque to 55-60 ft-lbs. Install the Strongback CAUTION This is a two person activity.
9 Install the Strongback (continued) Tighten Pivot Bolt closing any visible gaps between the Strongback and the Mounting Sleeve Towers. Torque to 125-150 ft.-lbs. 10 Install the Cross-Bars CAUTION This is a two person activity. Cross-Bars are long and unstable before they are fully secured to the Strongback. Cross-Bars must be held in place by one person while the second person aligns and secures them to the Strongback. Failure to do so could lead to serious personal injury.
11 Install Rails CAUTION This is a two person activity. Module Rails are unstable before they are secured to the Rail Brackets. When installing the Rails orient their profiles as shown. Be sure to align the correct side of the Rail with the Rail alignment marks on the Cross-Bars. Align the Rail to the alignment marks and straddle its mounting holes over the Cross-Bar.
12 Install Modules CAUTION This is a two person activity. Modules are heavy and unstable before they are fully secured to the Module Rails. PV Modules must be held in place by one person while the second person aligns and secures them to the Module Rails. Failure to do so could lead to serious personal injury and damaged components. Align Module mounting holes with the installed Double Hole Slide Plates and secure Module with 1/4” x 3/4” Hex Bolt, Flat Washers, Lock Washer and Hex Nut.
14 Adjust the Array Tilt Angle WARNING Do not attempt to remove the Pivot Bolt during tilt adjustments! Removal could lead to serious personal injury or death. Adjustments are made with the Pivot Bolt hardware loosened but in place. CAUTION This is a two person activity. As the hardware is loosened, the rack is heavy and unstable. The rack must be held in place by one person while the second person loosens the hardware and then re-installs and tightens the hardware back in place.
