PLANNING YOUR NXT UMOUNT INSTALLATIONS
The installation can be laid out with rails parallel to the rafters or perpendicular
to the rafters. Note that NXT UMOUNT rails make excellent straight edges for
doing layouts.
Center the installation area over the structural members as much as possible.
Leave enough room to safely move around the array during installation.
Some building codes and re codes require minimum clearances around such
installations, and the installer should check local building code requirements
for compliance.
The length of the installation area is equal to:
• the total width of the modules,
• plus 1/2” for each space between modules (for mid- clamp),
• plus 2" minimum ( 1” minimum for each MODULE END) (This will not be
included when we use the hidden end clamp.)
LAYING OUT ROOF ATTACHMENTS
Locate and mark the position of the roof attachment within the installation
area. Refer to Unirac NXT UMOUNT D&E Guide & U-Builder for rail spans and
cantilevers. Follow module manufacturer installation requirements allowable
spacing based on appropriate mounting locations. Modules should be placed
such that they overhang the rails symmetrically.
NXT Rail Splices are fully structural and do not interfere with roof attachments or Combo Clamps.
There is no need to determine splice locations at this stage.

THERMAL BREAK
EXPANSION JOINT USED AS THERMAL BREAK
Expansion joints prevent buckling of rails or system connection failure
due to thermal expansion. Determine location of expansion joints prior to
installation of roof attachments and rails. To create a thermal expansion
joint, provide a sufcient gap between rails for proper installation of end
clamps and tooling to achieve required torque. A thermal break is required
when a continuous length of spliced rails exceeds the maximum allowable
lengths shown in the table to the right. For additional concerns on thermal
breaks in your specic project, please consult a licensed structural engineer.
Rails in expansion joint congurations are considered cantilevered and
must follow the cantilever rule on both sides of the expansion joint, which
states that the maximum amount of rail that can be cantilevered is 1/3 the
respective adjacent span. An expansion joint must not be spanned by a PV
module. Installing a module over an expansion joint would defeat the goal
of a thermal break and could result in damage to the array.
Bonding connection for splice used as a thermal break. Option shown uses
two Ilsco lugs (Model No. GBL-4DBT P/N GBL-4DBT - see product data sheet
for more details) and solid copper wire. Optional grounding may be achieved
through NXT UMOUNT MLPE & Lug Clamp. See Page 16. The values displayed are the maximum allowed rail length, in feet, without a thermal
break. If your span is less than 48”, refer to the NXT UMOUNT Design & Engineering
Guide for max lengths of continuous rail before a thermal break is required.
Determine the maximum rail temperature difference (ΔT) between the time of
installation and the extreme high or low temperature. The Extreme Annual Design
Conditions table at the following URL can be used as a reference when determining
ΔT. http://ashrae-meteo.info/. The installer is responsible for determining the
maximum temperature difference (ΔT) used to establish the maximum rail length.
As spans increase, so does the maximum reaction force that the rail exerts on
the L-foot. Ensuring that the Maximum Reaction Forces do not exceed the shear
capacity of the roof connection. See NXT UMOUNT Design & Engineering Guide for
corresponding reaction forces.

clamps and tooling

STRONGHOLD ATTACHMENT WITH BUTYL
PLACING STRONGHOLD ATTACHMENT WITH BUTYL BASE:
Identify the position of the attachment to install before peeling the release
paper.
Ensure that the attachment lands on a at surface. If the surface at the location
of the attachment is uneven, add butyl patches to atten the surface.
MARK ARRAY LOCATION:
Clean roof surface of dirt, debris, snow, and ice. Mark array location and
determine roof attachment locations based on array layout. Snap chalk lines
to mark each row of roof attachment points. On shingle roofs, snap lines 1/4”
below upslope edge of shingle course. Locate rafters and mark at intersection of
attachment lines. Attachment spacing determined per Design and Engineering
Guide or project specic U-Builder Engineering Report .

STRONGHOLD ATTACHMENT WITH BUTYL
INSTALLING STRONGHOLD ATTACHMENT WITH BUTYL BASE TO RAFTER:
Peel-off the release paper from the underside of the attachment and place
stronghold attachment with butyl over rafter location and align edge of mount
with horizontal chalk line. Secure mount with the two (2) provided rafter screws
in the rafter holes of the attachment.
Note:
Ensure to use drill extension or deep socket tool for installing rafter screws.
CAUTION
• To determine if the screw is engaging the rafter, there should be resistance
to driving the screw through the entire length. If the screws do not properly
engage the rafter, install the 4 additional deck screws.
• It is recommended to begin installation with the screws on the upslope side
of the attachment and continue installing the screws on the downslope side
of the attachment for best t.
Do not over-torque the structural screw.
When proper torque is applied, the EPDM washer
should slightly expand out from the sides as shown in
the image.
WARNING
INSTALLING STRONGHOLD ATTACHMENT WITH BUTYL BASE TO DECK:
When installing the attachment to the decking instead of the rafter (direct-
to-deck), install 4 additional screws on the remaining screw holes on the
attachment
CAUTION
1. Allowable attachment spans may change for direct-to-deck applications.
2. Unirac recommended spans are only valid with Unirac supplied screws.
Note:
• Additional deck screws are NOT included in the KIT. Must be purchased
separately.
• Pre-stock with additional screws in case going direct-to-deck.

STRONGHOLD ATTACHMENT WITH BUTYL
INSTALLING STRONGHOLD DTD BUTYL ATTACHMENT OVER SHINGLE OVERLAP OR GAP
If the attachment falls over a shingle overlap, level the surface by following below steps:
A. Measure the attachment overhang.
B. Cut the butyl pads to required size.
C. Stack extra butyl pad layers as necessary to level the roof and place the attachment.
D. Begin installation with the screws on the upslope side of the attachment and continue to install the screws on the downslope side of the attachment.
PRO TIP
If the attachments overlap from one shingle course to the next shingle course in a rail-based system, reposition the attachment by moving up or down the shingle
course along the same rafter line to avoid butyl layering.
Note:
• Extra butyl pads are NOT included in the KIT.
• Pre-stock with extra butyl pads from Unirac Kits in case installation is required over overlap or gap.

RAIL INSTALLATION
POSITION RAIL ONTO RAIL CLAMP:
With the bolt in the pre-assembled (loose) position, Insert the rail ange on one side of the clamp
groove. Then click-in the other side of the rail into the clamp groove.
ALIGN RAILS: Align one pair of rail ends to the edge of the installation area. The opposite pair of rail
ends will overhang installation area. Do not trim them off until the installation is complete. Install
the rst module at the aligned end. If the rails are parallel to the rafters, the aligned end of the rails
should face the lower edge of the roof. Securely tighten all hardware after alignment is complete.
Mount modules to the rails as soon as possible. Large temperature changes may bow the rails within
a few hours if module placement is delayed.
TIGHTEN RAIL ONTO RAIL CLAMP :
Adjust the rail height as needed until
rail alignment is complete and tighten
bolt.

STRUCTURAL SPLICE
SPLICE INSTALLATION (IF REQUIRED PER SYSTEM DESIGN)
If your installation uses NXT UMOUNT Rail Splice, attach the rails together either
before installing the rail or after. Use marking on the splice for centering the
connection. To install, slide the splice into the rail on each rail and drag it to the center
of the marking. Tighten both bolts on each rail with an impact drill, pressing rmly
until the bolt-head is ush against the splice and torqued to 15 ft-lbs. Installation is
complete when the bonding hardware penetrates the opposite side of the rail, and the
assembly torque is achieved.
,,are the steps of installation.
TORQUE VALUE: 15 ft-lbs. Do not use Anti-Seize.
CAUTION
• If assembling splice directly on roof, take care to prevent bolts from penetrating
roof covering.
• While installing the splice, ensure either of the rails is not offset from the center
marking.
Note:
1. Maximum gap between rails should not exceed 3/16” at splice connection
2. Splice certied for single-use only
