Before You Begin:
A.
Select the correct trunk cable:
1. Mark the array footprint on the roof.
2. Locate rafters and determine attachment points.
3. Install roof attachments.
4. Install rails.
5. Level rails.
6. Torque attachment hardware.
7. Stage the trunk cable atop the rails according to circuit
layout; add terminator (if not yet installed) to the circuit end.
8. Install the Rooftop Transition Flashing (if composition
shingle roof); or equivalent.
9. Install the Rail-Mounted J-Box (RMJ), or equivalent, and
wire the non-terminator end of the trunk cable into it,
transitioning to the building wiring and equipment ground
conductor (EGC).
10. Attach a ground lug assembly to the rail, adjacent to the
RMJ.
11. Attach a 6 AWG copper ground wire to the lug, and connect
it to the EGC inside the RMJ using the included cable gland.
Install the cover on the RMJ.

B.
Prepare the trunk cable:
• Determine the array circuit layout,
noting the number of connectors that
will NOT plug into a module (due to
row transition or irregular array shape),
then cut a section of trunk cable that
has one connector per module PLUS
that number. Add a sealing cap to each
skipped connector.
• Add a terminator (
C.
) to the trunk cable
where the circuit will end (you may
instead do this on the roof after you
stage the trunk cable).
C.
Add a terminator:
1. Remove 1/2
”
of outer sheathing from one
end of the trunk cable
—
DO NOT remove
the black and red insulation on the two
conductors. Very slightly separate the two
conductors.
2. Slide the nut over the cable, with its
threads facing away.
3. Fit the cable end into the terminator and
carefully insert it such that each of the two
conductors is internally separated by the
terminator. (Ensure that the white inner
grommet stays in place.)
4. Use a screwdriver through its end to
stabilize the terminator, and then tighten
the
nut
only
—
DO NOT ROTATE THE
TERMINATOR!
5. Use cable clips to manage the terminated
end of the trunk cable such that it is not
visible and does not contact the roof.
Important!
Terminators are single use
only!
