9910048 RevC February 2020
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 30 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 5 Degree,
please follow the instructions below in Appendix B: 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
follow the instructions below in Appendix D: Electrical Grounding (Non
2703 PV Module).
ALERT: During grounding and bonding ensure there is separation
between bare copper and aluminum or ZAM coated steel components.

9910048 RevC February 2020
Appendix A: Safety
The subsections below outline some of the obvious / major hazards that could exist during the installation of PanelClaw products and are
divided to bring a level of clarity to such hazards. Some sections do not apply to all PanelClaw product lines and such exclusions are noted
within each section.
Electrical Hazards: PanelClaw products are purely mechanical and do not contain any electrically live parts. When a photovoltaic module is
exposed to sunlight it is electrically live and cannot be turned off. As soon as modules are installed using a PanelClaw system, an electrical
shock hazard is present. All personnel on site should coordinate to ensure that such electrical hazards are clearly communicated. It is advised,
at a minimum, that all personnel utilize caution and proper Personal Protective Equipment as outlined in that section. Only electrically
qualified personnel should perform PV module installation. Refer to OSHA Part 1926 Subpart K –Electrical and NFPA 70E for additional
information.
Fall Hazards: This section only applies to clawFR® products installed on locations six feet or higher above grade. Proper fall protection should
be in place at all work sites. There are many fall protection solutions readily available to help reduce exposure to fall hazards. These may
include personal fall arrest systems, safety nets, guardrails, and flagged setbacks from all roof edges as outlined in OSHA Part 1926 Subpart M
–Fall Protection.
Trip Hazards: All PanelClaw arrays have elevated components that are installed above grade or above a roof surface. Such hazards should be
identified and caution should be taken to avoid tripping over such components. Refer to the Fall Hazards section specifically if working with
the clawFR product line. Make sure to pick up and not drag your feet when working on site, and always pay attention to your path of
movement to note any obstructions that could create a trip hazard.
Lifting Hazards: The PanelClaw installation process involves lifting of heavy items that could lead to personal injury and damage to property.
All personnel should be trained in the proper procedures for manually lifting. Evaluate an object’s size and weight prior to lifting, and follow
these general guidelines for lifting:
1. Assess the lift and know the object weight.
2. Bend at the knees and get a good grip.
3. Keep back straight and lift straight up with legs without twisting. It is important to lift with the legs and not the back.
4. If an object is too large or heavy, ask for help and do not attempt to lift by yourself. In the case that mechanical assistance (e.g. crane,
forklift, etc.) is required to complete the lifting operations, all machine operators of such devices should be licensed and trained.
PAGE 16

9910048 RevC February 2020
Appendix A: Safety (Contd.)
Material Handling: All PanelClaw parts and components are made of aluminum and steel alloys and utilize stainless steel and steel alloy
assembly hardware. These materials are considered non-toxic and require no special handling procedures. Metal components may have
sharp edges, so be sure to handle with care and utilize proper personal protection equipment, especially gloves, during handling. Refer to
OSHA Part 1926 Subpart H –Materials Handling, Storage, Use, and Disposal for additional information.
Personal Protective Equipment (PPE): All personnel should utilize and implement proper PPE per OSHA requirements. Refer to OSHA
requirements for proper use and implementation of PPE. The following items are suggested as a minimum to avoid injury based on the
installation procedure outlined in this manual:
1. Appropriate work clothing
2. Electrically insulated hard hat
3. Protective eyewear
4. EH rated safety boots
5. Gloves
6. High-visibility safety vest
7. Hearing protection
If any PPE appears to be defective, stop the use of such equipment immediately, and ensure it is replaced before work continues. Refer to
OSHA Part 1926 Subpart E –Personal Protective and Life Saving Equipment for additional information.
Hand and Power Tools: Access to all hand and power tools should be regulated and controlled at all times on site to prevent improper use
and related injuries. When not in use, all equipment should be stored in a secured location. Only personnel who have been properly
trained in the safe operation of any potentially dangerous tool should be allowed access. All required tools to perform the installation of
PanelClaw racking are outlined in the installation procedure. All tools should be inspected daily and before use by the operator. If any tool
appears to be defective, stop the use of such equipment immediately, and ensure it is replaced before work continues. Electrical power
tools should follow proper lock-out tag-out procedures per OSHA requirements. Refer to OSHA Part 1926 Subpart I –Tools –Hand and
Power for additional information.

9910048 RevC February 2020
Appendix B: UL 2703 Grounding
The clawFR 5 Degree flat roof system may be
used to ground and/or mount a PV 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.
