The previously assembled
bearing block and vertical post
assembly from step 3 are inserted
into the sigma posts with the short
vertical posts serving as the front
and the longer vertical posts as
the rear legs of the array.
The posts are aligned on site in
accordance with the tilt angle
of the rack; a minimum lapped
joint length of approximately
12 in. (200 mm) is needed for
attachment.
The base rails (ST-AK 182-120) are fastened
to the bearing blocks with 4 T-bolts assemblies
attached by sliding head of the T-bolts into the two
slots on the bottom of the base rails (ST-AK 182-
120)on the north-south axis.
See Figure 5.1
The T-Bolts must be turned 45° clockwise until
they cannot be turned any further.
A line on the bottom of the T-Bolts shows proper
alignment. Line must be perpendicular to rail.
(Torque hex nuts: 10 ft. lbs.)
See Figure 5.2
Base rail is now securely fastened to the bearing
block.
See Figure 5.3
After the frame is complete
the system must be fixed to the
sigma post with the supplied
M10 x 120mm hardware. The
vertical posts can be moved
up and down to achieve the
required tilt angle. When the
correct angle is achieved a
cordless drill with a 7/16 bit
must be used to drill through the existing holes in the sigma post and through
the aluminum vertical post before the hardware can be installed. Again, the
vertical post must contact the sigma post for a minimum of 12 in. (200 mm).
(Torque: 10 ft. lbs.)
After the system rails are attached
to the bearing blocks, the upper
module rails are attached
lengthwise. This requires 4 cross
adapters per intersection point.
Click the cross adapters onto the
base rails and slide attachment
lip into channel on base rail.
Fasten the clamp screws by turning
clockwise.
See Figures 6.1 &
6.2
(Torque: 10 ft. Lbs)
Module mounting rail is now properly fastened to base rails. Four cross
adapters are used at each of these connections
To line up several system rails
with one another, slide the splice
halfway onto the assembled
system rail until rivet on splice stops
forward movement.
Next, slide the other system rail
onto the splice. Push complete and
add cross adapter if applicable.
Splice does not have to occur at a
cross rail. Splice is now properly
installed and will allow the rail to perform under thermal expansion and
contraction. Do not attempt to through-bolt splice. ½” gap or separation
between rails is required for thermal expansion.
