Safety Overview
Safety is an essential part of every PV installation and every
construction site. It is imperative to plan ahead for any safety
concerns and hazards to promote safe work practices during
installation. This section does not claim to address or support all
safety concerns that may arise during the installation of PanelClaw
mounting systems or any other aspect of the work being
performed. Before beginning work, installers should refer to all
local and federal safety, health, and regulatory requirements to
assure compliance. Refer to OSHA Part 1926 and its related
Subparts for federal construction related regulations and
standards.
Appendix J: Safety outlines some of the major hazards to be aware
of during the installation of PanelClaw products.
PRIOR TO INSTALLATION, READ THE SAFETY PROVISIONS
ATTACHED IN Appendix J: Safety AND REVIEW THIS
INSTALLATION MANUAL IN ITS ENTIRETY.

9910046 RevG April 2021 PAGE 3
Storage Considerations
PanelClaw recommends installing the racking components shortly
after delivery to the project site. If clawFR components are not
deployed immediately, they should be stored in a well-ventilated,
dry location. Otherwise, moisture can form between the packed
components which may cause staining and/or white rust.
Significant white rust formation may decrease the coating service
life and, in extreme cases, the component performance.
If storage onsite is unavoidable, remove the plastic and/or
carboard wrapping from the exterior of the packaging and cover
with canvas or place components under an open sided tent. Note
the use of a plastic cover does more harm than good as it prevents
the product from breathing and causes condensation. Storing parts
in any other manner is at the customer’s own risk. PanelClaw is not
liable for claims related to improper storage and any such claims
are not covered by the product warranty. Operations & Maintenance
See O&M Manual, available upon request, for initial inspection
recommendations including steps that can be performed only
during construction.
Sub Array Dimensions
Each PV system is unique and is frequently made up of multiple
sub arrays. The Racking Construction Set, which must be onsite at
all times during construction, details sub array dimensions and
location on the roof. Review the Racking Construction Set in its
entirety to prevent unnecessary rework during site construction.
The furthest extent of the racking components or modules of
adjacent sub arrays, whichever defines the outermost array
boundaries, must be separated by at least the minimum
dimensions documented in the Racking Construction Set. Refer to
the general notes and the Minimum Clearance Requirements
table, if present, within the Racking Construction Set.

Place gauge against Lock Claw and underside
of module.
Select a Lock Claw which has been
confirmed to be installed correctly
through visual inspection.
The Tilt Arm and Lock Claw should
be aligned with the module frame
and the Lock Claw fully engaged
on the frame.
Mark line on gauge to finish setup.
Use gauge to confirm full Lock Claw
engagement-line must be visible.
8. Cam & Lock Claw Inspection
Inspect Cam side module connection
Module and Cam are near flush.
Module and Cam have a large
non-uniform gap.
Cam installation can be quickly visually
inspected (no gauge is available or
required) by comparing a known good
installation with all other installations.
Some gap between Module and Cam
is permissible. The graphics are
representative only; actual installation
geometry varies by module vendor
and part number. If it is not clear the
module low side connection is good,
contact PanelClaw for assistance.
ALERT: Verify correct installation by
lifting up on the module near the Cam
and making sure no movement occurs.

9910046 RevG April 2021
Electrical Grounding
Please consult with national and local building code(s) for
complete grounding requirements for your installation. The
clawFR grounding method conforms to ANSI/UL 2703 and is
certified by SolarPTL for use with approved photovoltaic
modules listed under ANSI/UL 1703 and/or ANSI/UL 61730.
Installers can quickly and easily establish ANSI/UL 2703
certified electric bonds between all connected array
components, including modules and mounting system
components, without the use of additional grounding
devices, e.g. ground lugs and copper wire. At least one
ground lug must be used to ground all strings within a
physical sub-array provided the fuse rating for each string
does not exceed 40 amps. Installers may opt to use multiple
lugs per sub-array for redundancy. When grounding devices
are installed according with the approved methodology and
capacity below, the connections described above meet all
the requirements outlined in NEC 690.43.
Grounding Instructions
For modules that have been evaluated for use with clawFR Dual Tilt 10
Degree, please follow the instructions below in Appendix A: UL 2703
Grounding. Additional information regarding ANSI/UL 2703 and the
specific list of evaluated modules included in PanelClaw’s UL listing can
be found in the “clawFR UL Overview and Module Listing” document
(available at www.panelclaw.com).
For modules that have not been evaluated for use with clawFR, please
contact PanelClaw
ALERT: During grounding and bonding ensure there is separation
between bare copper and aluminum or coated steel components.
PAGE 18

9910046 RevG April 2021
Appendix A: UL 2703 Grounding
The clawFR Dual Tilt 10 Degree flat roof
system may be used to ground and/or mount
aPV module complying with ANSI/UL 1703
or ANSI/UL 61730 only when the specific
module has been evaluated for grounding
and/or mounting in compliance with the
included instructions. For a list of modules
which have been evaluated see PanelClaw’s
“clawFR UL Overview and Module Listing”
(see www.panelclaw.com).
A periodic re-inspection of the system shall
be performed for loose components, loose
fasteners, and any corrosion. If found, they
should be immediately replaced or remedied
in accordance with the system installation
instructions.
System Ground Path
The system ground path “grid” is established throughout the array by the interconnection of system components. Specifically, in the column
direction via the Base and Module Connector connections and in the row direction via the Rail connections. A Tyco lug connected to the Rail
establishes a point of connection for the EGC at one location with a contiguous array. All modules are grounded to the system through their
Cam to Module connection.
Note: The presence of aPV module does not affect the bonding ability of the clawFR system components. More precisely, the grid provides
a means to ground PV Modules which have been evaluated for ANSI/UL 2703 grounding with clawFR.

Tyco Grounding lug attachment:
To attach the Tyco grounding device/lug to the Rail, the mounting hex washer and threaded post end should be installed to the specified hole
in the Rail and torqued to 2.08 ft-lb (25 in-lb).Once the grounding device/lug has been attached to the Rail, a copper bonding jumper from an
acceptable DC grounded location outside of the array must be installed to the wire slot end and torqued to 3.75 ft-lb (45 in-lb). For additional
instruction regarding the installation of the Tyco solid wire grounding assembly, please refer to the Tyco Electronics instructions sheet
(document number 408-10262) via their website www.te.com.
Grounding Instructions:
PanelClaw components within the array are required to be
electrically bonded to other DC grounding paths via the use of
appropriately sized Cu wire and a UL 467 listed Tyco Solarlok
grounding assembly, part number 2106831-1, manufactured by
Tyco Electronics Corporation. The conductor size should be
selected in accordance with NEC 690.45 and NEC 250.122.1.
To ground the array, first determine the groupings of strings
whose power output wiring is grounded together at an
equipotential grounding conductor location. This could be all
the strings within a physical sub-array, or all the strings grouped
by a single combiner box. Once the groupings of strings at
equipotential have been determined, a Tyco solid wire
grounding assembly must be attached to one Rail within each
group of strings. PanelClaw’s clawFR Rails have a hole to which
this grounding device/lug can be attached. In an array that
requires multiple bonding jumpers to satisfy the equipotential
requirements, each bonding jumper should be located and
installed on a Rail within the group of strings which will be
grounded by that jumper.
ALERT: Every sub-array must include at least one grounding
device/lug.
