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 ft -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. Th
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.
• Th
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.
