Page 5 of 12 Assembly Instructions UPM 12XHD, 15X, 18X Place pivot cap on top of steel post. Orient pivot bore with bronze bushings east and west. The 4 set bolt nuts should face south. Secure the pivot cap with ¾” square head set bolts. It is essential that you bolt the winch foundation/bracket to post approximately 1” below pivot cap. Use level to center foundation lugs plumb with center of pivot bore. Securely tighten bolts before installing winch. Bolt winch to foundation/bracket with 3 – ½” bolts.
Page 6 of 12 Place 4” block of wood on top of pivot cap. Keep 2 wedges handy. This block MUST NOT BE REMOVED until telestrut, winch and cable are installed and fully secured. Severe injury may result if center tube pivots without block or telestrut/winch restraining or controlling it! Lower center tube onto pivot cap. Line up holes in the center tube lugs with bore in the cap and insert 13” bolt. Note: 1 washer should be under nyloc nut.
Page 7 of 12 Install the 2 ¼” x 2 ¼” end of telestrut between the lugs on the bottom of the pivot cap. Tighten the nyloc nut all the way. Bolt telestrut bracket to longitudinal with 3 ½” sq. u-bolts. The dimension between the “west” lug on the bracket and the inside of the cross piece for your specific mount can be found on the attached table. Insert 7/16” bolt through lugs and upper end of telestrut and tighten.
Page 8 of 12 Attach orange pulley to pad eye on telestrut bracket. Thread cable with quick link connector through pulley before closing pulley hanger with 3/8” bolt and nyloc nut. Now attach quick link to hole on left side of winch foundation (see attached Winch Detail). Fully tighten collar on quick link. Pull tension on cable as it comes off winch drum and cut zip ties. Take up slack in cable by turning winch handle while still holding tension on cable. This will prevent it from jamming in winch drum.
Page 9 of 12 Before proceeding, tighten 5/8” bolts at the end plates of center tube. Place 2 aluminum channels or angle on top of the longitudinals. Loosely attach 4 square u-bolts in holes provided at the bottom of the channels, or brackets for angles. Loosely place 2 PV panels on rail and attach to establish rail spacing. Center rails on longitudinals by equally measuring side to side to longitudinal ends. Then place the rest of the panels on the rails.

Page 11 of 12 LONGITUDINAL STEP 1 Bolt winch to winch foundation with 3 – 3/8” grade 8 bolts – put flat washer on each side of winch/foundation interface. STEP 2 Attach red snatch block through “eye” in telestrut bracket. Before closing snatch block thread ¼” cable around sheave of pulley. Then attach quick link at end of cable to hole drilled in winch foundation. Tighten collar with a wrench. Asdfas Be sure to thread nylon nut on closure bolt for snatch block all the way down to end of threads.
Page 12 of 12 WARNING!!! Serious Injury or Property Damage may occur if array shifts while adjusting tilt angle without a safety line or winch attached and secured! DO NOT stand between post and lower side of the array while seasonally adjusting tilt angle. AND Use the winch you purchased with your mount, or tie a safety rope to top of array and wrap around car bumper or heavy permanent object to control adjustment of array.
