Top-of-Pole Mount for 12 Modules (TPM12) For Module Types A, B, & C A few words about the product The TPM12 for module types A, B, & C is designed to mount on 6 inch SCH40/80 galvanized steel pipe (installer supplied). Pipe size and foundation requirements are based on several factors including the array surface area, maximum design wind speed, exposure category, soil type, steepest expected tilt angle, and above-ground clearance.

Step 1: Install the Mounting Sleeve on Vertical Pipe CAUTION: Use care while working around the structure during assembly. There could be components that create hazards or obstruct free movement causing serious bodily injury. Many are at head/eye level. Move slowly and with care around the work area. Before installing the Mounting Sleeve, verify that the Mounting Pole is plumb to the ground and hasn't shifted or leaned while the concrete footing has cured.
NOTE: Although this system offers six elevation set points, for ease of assembly, set the angle to its lowest setting of 15-degrees. Optimum tilt setting of the rack will take place later in these instructions. B. Remove the Pivot Bolt from the Mounting Sleeve and collect the 3/8” x 1-3/4” bolt, flat washers and lock washer needed to secure the Support Bar to its Pivot Tab on the Mounting Sleeve. C.

CAUTION: Be sure to place the 3/8” square washers on the surface of the Cross-Bar and not the Mounting Angles of the Strongback. Failure to do so will damage the surface of the Cross-Bar when the attaching hardware is tightened.

Start by installing the inboard sections of Module Rail first and work outward. A. Referring to Figure 4-1 for orientation of the inboard Module Rails, position the first section of Module Rail (with its angle cut end positioned north) at the northern most position on the Cross-Bars. Align the Module Rail mounting holes with the holes of the Cross-Bar mounting tabs and secure with 3/8” x 1” bolts and hardware. Finger-tighten for now.

A. Referring to Figure 4-1 for orientation of the outboard Module Rails, position the first section of Module Rail (with its angle cut end positioned north) at the northern most position on the Cross-Bars.
N W Beveled-End E S Strongback Cross-Bar NOTE: Double check the orientation of inboard to outboard Module Rails. If they are installed differently from these instructions the mounting holes will not align to the holes of the PV Modules.
CAUTION: This is a two person activity. PV 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. Step 5: Installing PV Modules to Module Rails PV Modules are secured to the Module Rails using 1/4” x 3/4” bolts and hardware.
CAUTION: 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 Pivot Bolt is loosened and the Support Bar hardware is removed, the rack is heavy and unstable. The rack must be held in place by one person while the second person loosens and removes the hardware and then re-installs/tightens the hardware back in place.
C. Re-tighten the Pivot Bolt. After changing the tilt angle and tightening the Support Bar hardware, the Pivot Bolt must be re-tightened. The Pivot Bolt cannot be left loose - the Mounting Sleeve Vertical Towers must be firmly clamped to the sides of the Strongback, eliminating any gaps between the Vertical Towers and the Strongback. Torque to 125-150 ft.-lbs.
