General Safety Information
Please note that our general mounting instructions must be followed at all times and
can be viewed online at https://k2-systems.com/en-US/downloads/documentation
T The equipment may only be installed and operated by
qualified and adequately trained installers.
T Prior to installation, ensure that the product complies
with on-site static loading requirements.
For roof-mounted systems, the roof load-bearing
capacity must always be checked.
T National and local building regulations and environmental
requirements must be adhered to.
T Compliance with health and safety regulations, accident
prevention guidelines and applicable standards are
required.
·Protective equipment such as safety helmet, boots and
gloves must be worn.
·Roofing works must be in accordance with roofing
regulations utilizing fall protection safeguards when
eaves height exceeds 3 m.
·At least two people must be present for the duration of
the installation work in order to provide rapid assistance
in the event of an emergency.
T K2 mounting systems are continuously developed and
improved and the installation process may thereby
change at any time. Prior to installation consult our
website at:
https://k2-systems.com/en-US/downloads/
documentation for up-to-date instructions.
We can send you the latest version on request.
T The assembly instructions of the module manufacturer
must be adhered to.
T Equipotential bonding/grounding/earthing between
individual parts is to be performed according to
country specific standards, as well as national laws and
regulations.
T At least one copy of the assembly instructions should
be available on site throughout the duration of the
installation.
T Failure to adhere to our general safety and assembly
instructions and not using all system components,
K2 is not liable for any resulting defects or damages. We
do not accept liability for any damage resulting in the use
of competitor’s parts. Warranty is excluded in such cases.
T If all safety instructions are adhered to and the system
is correctly installed, there is a product warranty
entitlement of 25 years! We strongly recommend
reviewing our terms of guarantee, which can be
viewed at https://k2-systems.com/en-US/downloads/
documentation
We will also send this information on request.
T Dismantling of the system is performed in reverse order
to the assembly.
T K2 stainless steel components are available in
different corrosion resistance classes. Each structure
or component must be carefully checked for possible
corrosion exposure.

The following guidelines apply
The CrossRail System can be installed as standard under the following conditions. Even if the
system is capable of meeting higher demands through the integration of safety standards,
please get in touch with your contact at K2 Systems if the specified values are exceeded.
Roof requirements
T The structural integrity of the roof must be
reviewed on site and approved by a licensed
structural engineer.
T Roof mean height: 0-60 ft
T For allowable roof pitch, refer to the CrossRail
engineering letters on our website: https://k2-
systems.com/en-US/technical-information/
downloads
Structural requirements
T Wind speed: 95-200 mph
T Ground snow load: 0-100 psf
T Clearance: 2" to 10" clear from the top of the
roof to the top of PV panel
T Maximum cantilever: L/3 where "L" is the
span noted in the engineering span tables,
provided there is at least 1 module length
between maximum cantilevers.

Bonding and Grounding
Appropriate means of bonding and grounding are required by regulation. The information provided in this manual shall
always be verified with local and national building codes.
Everest Solar Systems has obtained a UL 2703 system listing from Underwriter’s Laboratories (UL).
A sample bonding path diagram is shown in Figure 1 below. Your specific installation may vary, based upon site conditions
and your AHJ‘s requirements.
Each electrical connection has been evaluated to a maximum fuse rating of 30A. At least one ground lug per row of
modules must be used to ground all strings within each sub-array, although additional may be used for redundancy. When
installed per these installation instructions, all connections meet the requirements of NEC 690.43.
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.

Fire Rating
The CrossRail System has undergone fire performance testing in accordance with UL 2703, Fire Performance.
A System Class A fire rating is achieved when using CrossRail 44-X/48-X/48-XL under the following
conditions:
T Roof slope of 2/12" rise per linear foot or greater
T Used in combination with a UL 1703 Listed module with a fire performance rating of Type 1, Type 2, or Type
3. Consult the module manufacturer for specific fire performance rating information.
T CrossRail may be mounted using any stand-off height to maintain the Class A fire rating. Always consult the
module manufacturer‘s installation instructions to ensure your installation is in compliance with their UL
1703 Listing.
T The results of the racking system do not improve a roof covering Class rating.
All documentation can be found on UL‘s Online Database as well as K2 Systems‘ website.

a mid clamp.
Important note for Yeti Clamp installs

Assembly
Composition Shingle
!
!
Locate and mark rafters using a hammer and chalk. Snap horizontal
chalk lines within the desired shingle course to mark the rows of
roof attachments. Drill a 7/32" pilot hole on your marks where roof
attachments will be located. Consult a professional roofer to ensure
Backfill the pilot hole with roofing manufacturer's approved sealant. Also,
put an upside-down "U" shape bead of sealant around the hole on the
back side of the flashing. Install the flashing so that it sits on top of the
first shingle course, under the second course above, and reaches under
the third course to create headlap. The bottom of the flashing should sit

Line up pilot hole with the flashing hole. Insert the lag screw through EPDM
bonded washer, L-Foot, gasketed hole in flashing and into rafter. To roperly
fasten the lag screw and create a watertight seal, drive the lag until the EPDM
sealing washer is seated flush against L-Foot. Over tightening the sealing
washer will flatten and tear the EPDM, compromising the seal. See Figure F1..
Insert T-Bolt through L-Foot slot and into side channel of CrossRail. Turn the T-Bolt clockwise ensuring that the mark
at the end of the shaft is vertical, indicating proper alignment. Tighten to 25.8 ft-lbs (35 Nm).
Due to thermal expansion, we recommend placing a gap of 1.25"-2" (3-5cm) every 65 ft (20m) between
rails. Maximum allowable spacing between thermal expansion gaps shall not exceed 80 ft (24.4m).
In areas that experience snow loads, install the rail on the roof-ridge side of the L-Foot.

!Align the two rail ends next to each other. Slide rail connector from below
the rails, centering the connector between the rail ends. Attach rail
connector using two T-Bolts and Serrated Hex nuts per side (4 total).
Use the CrossRail Microinverter & Optimizer Mounting Kit hardware
from K2 Systems. Attach your chosen device to the top channel of the
CrossRail. Torque the 13mm Hex Bolt to 10.3 ft-lbs (14 Nm).

!Insert MK3 slot nut of the preassembled end clamps into the top
channel of the CrossRail. While slightly lifting the plastic tabs, rotate
90º clockwise to engage the MK3 into the channel. Torque the M8 bolt
to 10.3 ft-lbs (14 Nm).
!Push zip tie into leash channel located on bottom of Yeti Clamp. Slide clamp into the rail channel with
bolt facing outward. Leave enough room for module to be place. Place module flush to end of rail. Pull
leash toward you so that the clamp slides over module frame and tighten to 10.3 ft-lbs. Use your hand
to check that the Yeti Clamp is fully engaged with the frame of the module, as shown in the image.
Note: The Yeti Clamp must be installed in an array. It can-not be installed on a single module that is not
connected to the array by a mid clamp.
