3.1.(m):
Collectors: Check that mounting post is an equal distance vertically from each
conductor bar. This will provide equal tension per collector. Each collector is to be centered on
the conductor on which it is to travel.
3.2: System
with
Expansions
The following are general system installation guidelines; see the following sections for specific component installation instructions.
3.2.(a):
Check alignment of mounting brackets prior to assembling hangers and bar. Correct any
brackets that are misaligned. Mounting brackets should not exceed ¼” in horizontal and vertical
misalignment over 5’0” mounting centers.
3.2.(b):
To expedite assembly, it is recommended that the hanger brackets be loosely
assembled to the mounting brackets prior to hanging the mounting brackets.
3.2.(c):
Anchor hangers will be located on mounting brackets: 120 ft. from the centerline of the
expansion assembly on 90 Amp and 110/125 Amp systems; 80 ft. from the centerline of the
expansion assembly on 250 Amp and 400 Amp systems.
3.2.(d):
Begin system assembly by installing the expansion assemblies or the first set of
expansion assemblies. Locate the end of the expansion (joint) approximately 2½ ft. from a
hanger – this will prevent joint/hanger interference as the system is assembled.
3.2.(e):
Once the first set of expansion assemblies are assembled to the mounting brackets,
begin to assemble additional conductors to the system in one direction from the expansion.
3.2.(f):
The expansion gap will need to be set as per the chart located on page 23.
NOTE: Set gap to the appropriate dimension. This will need to be verified prior to clamping the
anchor hangers.
3.2.(g):
Continue to assemble the system in one direction through the anchor hangers (do not
tighten at this time) to the end or to the next expansion assembly.
3.2.(h):
Between each individual bar, a joint and a joint cover must be mounted. When
assembling a joint, the following items should be checked:
3.2.(i).(i):
The sections of the conductor bars are assembled tightly together (never to
exceed 1/8”
gap).
3.2.(i).(ii):
The joint assembly is centered over the end of each bar.
3.2.(i).(iii):
The joint is appropriately tightened and checked prior to installing the joint
cover.
3.2.(j):
Open each end on the joint cover and remove the packaging foam. Mount over joint,
prior to closing the end covers. Verify the centering tabs and the bottom of the cover are located
between the ends of each conductor cover and clear the collector slot.
3.2.(k):
Power feeds are designed to be mounted at system joint locations. Ensure that the
hardware is tightened appropriately and the power feed cover is properly located on the bar. Be
sure feed cables do not apply any additional stress on the conductor bars.
3.2.(l):
From the other end of the initial expansion assemblies installed, continue to install the
system in the other direction.
