Installation Instructions
S-5!® Warning! Please use these products responsibly! Visit our website or contact
your S-5! distributor for detailed installation instructions and available load test
results. The user and/or the installer of these parts is responsible for all necessary
engineering and design for the intended use of these parts in an assembly or
application. Note that a continuous ground must be followed in accordance with
National Electric Code (NEC), ANSI/NFPA 70. Installation in Canada must be in
accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian
Electrical Code, Part 1. For use with PV Modules having a maximum fuse rating
of 15A or less. Prior to installation, contact the local code Authority Having
Jurisdiction (AHJ) to determine the proper grounding requirements.
Install S-5! mini clamp. See mini clamp installation instructions.
1. Place mounting disc on the S-5! mini clamp. Secure Universal PV stud
through the mounting disc into the S-5! mini clamp. Using a 13 mm
deepwell socket on the PV stud’s hex nut, tighten universal PV stud to
140–160 inch pounds. Install one PV frame on top of the mounting disc
utilizing the module placement bevel guide to ensure proper placement.
2. Install a second PV frame on top of the mounting disc again utilizing the
module placement bevel guide to ensure proper placement.
3. Install the universal PV anchor grab to the universal PV stud, with the
anged nut to secure the two PV frames (see Diagram A). Tighten ange
nut to 100–120 inch pounds.
4. For end/edge conditions, use the EdgeGrab™. There are two assembly
options for the EdgeGrab, dependent upon the PV frame thickness. For
frame thicknesses 30–48 mm, install the EdgeGrab by placing the serrated
L-ange on top of the mounting disk (see Diagram B). Then, drive the
universal PV stud through the serrated L-ange and the mounting disk,
and into the S-5! mini clamp. The L-ange will be positioned beneath the
stud’s hex nut. Using a 13 mm deepwell socket, tighten the universal PV
stud to 140–160 inch pounds. Next, set the PV module atop the mounting
disk, making the thin edge of the L-ange ush against the PV frame. Slide
the top component of the EdgeGrab onto the stud, allowing the serrated
sides to interlock at the appropriate height. Add the ange nut to the stud
to secure the PV frame. Tighten ange nut to 100–120 inch pounds.
5. For frame thicknesses 34–51 mm, position the serrated L-ange atop the
stud’s hex nut. Proceed with the remainder of step four.
Note: An electric tool can be utilized for ease of installation provided proper torque is achieved.

suggestions for spacing of S-5!
mini clamps for PV arrays.
The following suggestions assume that determination has been made that the roof to which the S-5!
®
mini clamps will be attached is structurally adequate. Any loads imposed on the S-5! mini clamps will be
transferred to the panels. Panel seams must have sucient exural strength to carry these loads. Panels must also
be adequately attached to the building structure, and the structure must be sucient to carry these loads. The
makers of S-5! mini clamps make no representations with respect to these variables. It is the responsibility of the
user to verify this information, or seek assistance from a qualied design professional if necessary.
The key to frequency and spacing of attachment points for PV frames utilizing the S-5-PV Kit is to distribute loads to the
metal standing seam panels in a manner that is consistent with the intended distribution of loads from the roof panels
into the building structure. With very few exceptions, the attachment of a single S-5! mini clamp to the seam will be
stronger than a single point of attachment of the seam to the building structure. Hence the “weak link” is not the S-5! mini
clamp but the attachment clips that hold the metal panels to the building structure, or the beam strength of the roof
panel seam itself.
The most conservative approach to the spacing/frequency of PV frame
attachment to the roof is to determine the spacing/frequency of the
roof’s attachment to the building structure, then duplicate it at minimum.
Determining panel attachment spacing in one axis is very simple. Standing
seam panels’ attachment will be made using concealed hold-down clips
within the seam area of the panel. So, in that axis, the clip spacing is the same
as the seam spacing. The location of the clips along the seam (in the other
axis) can be determined by a) consultation with the roof system manufacturer
or installer, b) checking from the underside or, c) close examination from the
topside along the seam.
There will usually be a slight, but detectable, deformation of the seam at the
clip location visible from the roof’s topside. Many standing seam roof systems
are installed on "pre-engineered" steel buildings. The attachment spacing
in that industry is typically 5'-0" and is readily apparent by inspecting the
spacing of the structural purlins to which the panel clips are attached from the
roof underside (interior of the building).
If, for instance, the panel clips are spaced 5'-0" on center along the seam,
then use the 5'-0" dimension as a maximum spacing for the S-5! mini clamps.
(S-5! mini clamps may also be spaced at closer centers, but not wider.) When
modules are attached directly without racking in the landscape orientation,
this spacing dimension is dictated by the smallest dimension of the PV frame.
Using the roof panel clip spacing as a maximum spacing template for S-5! mini
clamps is a sound practice, whether the PV modules are attached directly to
S-5! mini clamps, or to a racking system and then to the S-5! mini clamp (and
panel seams). To evenly distribute loads, it is also necessary that each seam be involved in the nished assembly. Thus,
every time a seam is traversed, it should be attached. Such an attachment scheme should evenly distribute wind loads into
the building structure through the panels and their attachment, as was intended in the original roof construction assembly.
Please note these are only suggestions. Wind dynamics are complex, and S-5! advises review of the planned PV frame
attachment design by a qualied professional who understands wind eects and metal roof design and construction. In
certain solar installations, a design professional may determine that seams can be skipped as points of attachment, but
this determination must be made on a job-specic basis.
