Certification Details
SnapNrack Ultra Rail system has been evaluated by Underwriters Laboratories (UL) and Listed to UL/ANSI Standard 2703
for Grounding/Bonding, Mechanical Loading, and Fire Classification.
The Ultra Rail system has been designed in compliance with UL Standard 2703 Section 9.1 Exception, which permits
accessible components that are not part of the fault current ground path to not be electrically bonded to the mounting
system (e.g. roof attachments, array skirt, etc.). For more details on the integrated grounding functionality see the
Grounding Specifications section.
This racking system may be used to ground and/or mount a PV module complying with UL 1703 only when the specific
module has been evaluated for grounding and/or mounting in compliance with the included instructions. See the Grounding
Specifications for the list of modules tested with the Ultra Rail system for integrated grounding.
Ground Lugs have been evaluated to both UL 467 and UL 2703 Listing requirements.
Ultra Rail has been listed with the following Enphase microinverter models for grounding/bonding: M215, M250, and C250.
The Enphase microinverters are certified to be mounted to SnapNrack rail with the MLPE Attachment or to the module
frame with the Enphase Frame Mount. When installing the Enphase microinverters per the specifications in the MLPE
Installation section of this manual, the total roof-mounted PV system is bonded (modules, racking and microinverters)
and grounded through the Enphase ground circuit when the Enphase units are properly grounded through to the service
entrance. Therefore, no ground lugs or equipment grounding conductor (EGC) are required on the SnapNrack systems.
Ultra Rail has been Listed with the following SolarEdge optimizer models for grounding/bonding: P300-5NC4ARS, P320-
5NC4ARS, P370-5NC4AFS, and P400-5NC4AFS. The SolarEdge optimizers are certified to be mounted to SnapNrack rail
with the MLPE Attachment or to the module frame with the SolarEdge Power Optimizer Frame-Mounted Module Add-
On. When installing the SolarEdge optimizers per the specifications in the MLPE Installation section of this manual, the
total roof-mounted PV system is bonded to the optimizer backing plate (modules, racking and optimizers) and grounded
through the ground lugs installed on the SnapNrack rail. Therefore, it is not necessary to run an EGC to each SolarEdge
optimizer.
Note: Frame-Mounted Module Add-On has been evaluated for all modules except Suniva modules.
Ultra Rail has been Listed with the following Ginlong Rapid Shutdown Units for grounding/bonding: Solis-RSD-1G 1:1
and Solis-RSD-1G 2:2. The Ginlong Rapid Shutdown Units are certified to be mounted to SnapNrack rail with the MLPE
Attachment.
The mounting system Bonding Listing is only valid when installed with a Non-Separately Derived PV system. The PV system
is required to have a direct electrical connection to another source, such as connecting to the grid via a grid interactive
inverter.
SnapNrack recommends that bare copper never come into contact with aluminum.
Grounding/Bonding
The Ultra Rail system is Listed for mechanical loading for different load ratings depending on the mounting configuration
and PV module installed. For more details on the mechanical loading details see the Mechanical Loading Specifications
section.
SnapNrack engineered systems should only be used with SnapNrack components and hardware. Any application outside
of those specified in this Installation Manual and the Structural Engineering Report may void the warranty and structural
certification could become invalid.
If the module clamps have been engaged and need to be loosened and reengaged, SnapNrack recommends moving the
module frame 3mm to engage the bonding pin in a new location if required by the AHJ.
The UL Listing covers mechanical load ratings for the various span lengths, module orientations and positive, negative, and
side load ratings. These values can be found in the Mechanical Loading Specifications section.
SnapNrack recommends a periodic re-inspection of the completed installation for loose components, loose fasteners, and
any corrosion, such that if found, the affected components are to be immediately replaced.
Mechanical Loading
snapnrack.com
Fire
The Ultra Rail system has been evaluated for a Class A System Fire Classification for a Steep-Sloped Roof using Type 1 and
Type 2 modules. In order to maintain the System Classification, modules are clamped to the mounting rails between 0 and
12 inches from the top and bottom edges of the module.
The Ultra Rail system has been evaluated for a Class A System Fire Classification for a Low-Sloped Roof using Type 1 and
Type 2 modules. In order to maintain the System Classification, modules are clamped to the mounting rails between 0 and
16.3 inches from the top and bottom edges of the module.
The optional Array Skirt accessory has also been evaluated and the Ultra Rail system will maintain the Class A System Fire
Classification detailed above if installed with the Skirt.
Because the system was tested at 5 inches above the test roof fixture Ultra Rail can be installed without any height restric-
tions and will maintain the Class A System Fire Classification. See Rail Installation section for potential module-specific
height restrictions due to module temperature.

Installing and Leveling Rails
INSTALLATION INSTRUCTIONS
1) Set rails into the attachments
by dropping and snapping into
the mounts. Connect multiple
lengths of rail end to end using the
SnapNrack Ultra Rail Splice (see
“Ultra Rail Splice” section).
2) Level the bottom rail of the array
to the roof and tighten attachment
points.
3) Run a string line or spare rail
from the bottom rail to the top rail
and set desired pitch of the array
by adjusting the top rail, add L Foot
Extension or spacer if needed.
4) Level the top rail by moving the
string line down the length of the
rail, matching pitch over the entire
length of the array.
5) Level the remaining rails to the
string line by working out from the
middle rail, add L Foot Extensions
or spacers if needed.
6) Tighten all racking hardware.
Set attachments in the middle of
available leveling range to start.
Best Practice:
The minimum standoff height between the
modules and roof is as follows:
ò REC Solar, Yingli, and Suniva modules:
4.00”
ò ReneSola modules: 3.93” (100 mm)
ò Trina Solar modules: 4.53” (115 mm)
