Foundation Hole and Pole Guidelines
• e suggestions below are recommendations
only. It is the installer’s responsibility to
validate foundation parameters prior to
installation, a local geotechnical report may
be required to assess soil conditions. We
recommend consulting with a local engineer
familiar with local regulations and build site
requirements, including soil conditions, terrain,
and load criteria (wind, snow, seismic). All
of these parameters may impact foundation
requirements.
• If you are planning to make seasonal
adjustments to the solar array angle, use
the steepest angle that you plan to use for
foundation and pipe sizing to insure that the
pole and foundation are strong enough to
support the array, and that the desired minimum
ground clearance is maintained, at all projected
angles.
• Highlighted lines in the tables on the next 2
pages require schedule 80 pipe for the main
support pole.
• Dig hole according to recommended depth and
diameter. Remove or properly compact any loose material at the bottom of the hole.
• e pipe lengths listed in the following tables are based on having the pole pipe installed 2-3 inches from
the bottom of the dug holes. Use a brick, concrete block, tiles, or other non-organic solid material at the
bottom of the hole to support the pole on, allowing it to be raised above the bottom of the hole and allowing
the concrete to fully encapsulate the pipe pole. If using a thicker material, be sure to allow for the added
thickness when calculating the above-ground and total pipe lengths.
• Set pipe in hole and use a level to insure that it is straight and plumb in all directions.
• Brace pipe to prevent movement while pouring concrete. Pouring so that concrete is in direct contact with
the soil is recommended. If forming or using sonotube, properly compact backll. Allow concrete to cure for
recommended length of time.
Soil Classifications
• If in doubt about the soil type and holding strength, consult a local engineer.
• Class 3 - Sandy Gravel and/or Gravel - Lateral Bearing Pressure - 200 lbs/sq  below natural grade
• Class 4 - Sand; silty sand, clayey sand, silty gravel, and clayey gravel - Lateral Bearing Pressure - 150 lbs/sq 
below natural grade
• Class 5 - Clay, sandy clay, silty clay, silt and sandy silt - Lateral Bearing Pressure - 100 lbs/sq  below natural
grade

Step One - Pole Cap Assembly
• Place the Pole Cover on top of the mounting pole.
• Install the 3/4 x 6-inch Cap Support Bolt through the two top holes in the rear half of the
cap and install nut and tighten rmly. is bolt keeps the cap at the top of
the pole.
• Put the two 3/4 x 7-inch bolts into the back half of the mount, then
through the front half and put the nut losely on the bolts.
• Slide the assembled Cap over the 4-inch vertical pole.
• Rotate the cap on the pole so that the front (larger) half of the cap is on
the side of the pole the the array will be facing.
• Loosely install the four 1/2-inch set screws in the threaded holes on the
rear half of the cap. Do not tighten at this time.
• Securely tighten the two 3/4-inch
bolts in the cap assembly, but do
not fully torque to spec until nal
assembly is complete.
Step Two - Assemble Frame
• Slide one of the 2” Support Pipes (2-3/8-inch O.D.)
through the holes on the side of the front half of the Pole
Cap. Center the pipe in the Pole Cap.
• Install a Rail Support Blade to each side of this Support
Pipe with a 1/2-13 x 1-1/4-inch bolt, at washer and
split lock washer. Leave these bolts hand-tight until you
install the second support pipe.
• Attach the other 2-inch Support Pipe (2-3/8-inch O.D.)
between the two Rail Support Blades with a 1/2-13 x
1-1/4-inch bolt, at washer and split lock washer on each side. is support must be above the back section
of the cap when it is attached between the blades. Tighten the 4 bolts to 45 -lbs.

Step Three - Assemble Adjuster Arm
• Install the Adjuster Arm as shown in the image below. Attach it to the Support Pipe that does not go through
the holes in the Pole Cap with a 2-3/8-inch U-bolt and two ange nuts. Tighten hand tight to allow it to be
alligned with the tab on the Pole Cap Backplate.
• Attach the Adjuster Arm to the tab provided on the Pole Cap Backplate with a 1/2-13 x 1-1/2-inch bolt and
nut.
• Use the hole that makes the Rail Support Blades approximately horizontal for assembly purposes. is will be
readjusted in nal assembly.
Step Four - Module Mounting Rail Assembly
(for TTP-3 only)
• Assemble a 127.5-inch Module Mounting Rail by splicing an 85-inch rail and a 42.5-inch rail section using a
rail splice and two 5/16” x 1.125-inch bolts and channel nuts. Slip the splice 5-inches into the end of one rail
section, place a channel nut and bolt approximately 2.5-inches from the end and tighten. Slide the second rail
section over the splice, butting the rail section ends together, and repeat this process
• Tighten Splice Bolts to 12 -lb. If a Module Clamp needs to be placed between the two Splice Bolts, they will
need to be loosened to allow it to be inserted.
• Repeat this process for the second Module Mounting Rail.

Step Five - Rail Mount Attachment
• Attach a Rail Mount to
each of the 4 end holes
on the Rail Support
Blades. If the length
of the solar module
being used is less than
70-inches, place the Rail Mounts on the inside
of the Rail Support Blades. If the solar module
length is 70-inches or more, place the Rail
Mounts on the outside of the Rail Support
Blades. Leave the bolts on the Rail Mounts
loose until the Rails are installed.
Step Six - Module Mounting Rail Attachment
• Place one of the Module Mounting Rails on the two Rail Mounts installed
on the Rail Support Blades, and center it in the north/south direction so it
extends past both Rail Mounts the same distance. Make sure that the Rail
Mount slips into both of the mounting features on the bottom of the rails
(see drawing at right).
• Tighten the the 3/8-inch bolts with a 9/16-inch socket to 18 -lbs.
• Repeat above step for the other Module Mounting Rail.
System Grounding
• Tamarack Module Mounting Rails and the PV module frames are electrically
bonded together by the Tamarack Module Clamps. is creates a single electrically
bonded unit for grounding purposes per UL 2703 requirements. Only one Ground
Lug is required to provide equipment grounding for the entire column of PV
modules.
• e Ground Lug can be attached at any location desired on either one of the two Module Support Rails.
• Connect the ground lug to the ground wire in the system according to local code.

Mount Solar Modules on Rails
• To center the modules on the rails, calculate the amount of excess Module
Mounting Rail length:
1) Add the width of the modules plus 1/2-inch space between modules.
2) For TTP-2: subtract the above calculated number from 85-inches.
For TTP-3 subtract the above calculated number from 127.5-inches.
3) is will give you the total excess length of the Module Mounting Rails.
• Start module installation at the bottom. To center the column of modules on
the rails, place the rst two Module Clamps on the rails 1/2 of the total excess
rail length from the bottom of the rails. Be sure to put the side of the top
clamp with the two bonding pins inward toward the module frame.
• Center the rst module east to west over the rails and hold in place. Make sure
that the module is straight and level on the rails and tighten the two end clamp
bolts to 108 inch-pounds (9 foot-pounds).
• Install one Module Clamp in each rail on the other side of the rst module
and slide it down so that the inside of the clamp contacts the frame of the rst
module. e springs will hold the clamps in place prior to tightening. Place
the second module on the rails, align it with the rst module, and slide down
and fully into the two mid-clamps. Tighten the mid-clamp bolts to 144 inch-
pounds (12 foot-pounds) to fully secure the module. Install the third module
on TTP-3 in the same manor.
• On the top edge of the last module of the rst column, install the Module
Clamps so that the sides with the two stainless-steel pins are facing in toward
the module frame, and the clamp is tight up against the module frame.
Tighten the two end clamp bolts to 108 inch-pounds (9 foot-pounds).
Final Assembly
• Set the array tilt to the desired angle and tighten the Tilt Adjuster bolt to 40 -lbs.
• Tighten the U-bolt on the Tilt Adjuster to 20 -lbs.
• Rotate the array to point in the desired direction. Tighten the 3/4-inch nuts on the Pole Cap to 100 -lbs.
• Tighten all of the 1/2-inch set screws on the Pole Cap to 40 -lbs with a 3/4-inch socket.
