FS SystemTM Ground Mount Installation Manual
FS System
The Schletter FS System for ground mount photovoltaic (PV) installations is specifically designed to meet or exceed applicable IBC,
ASCE, and UL standards. For more information on the FS System, please see system brochure.
Features
• Conforms to UL 27031
• Certified to ULC/ORD STD C1703
• Electrically Bonded Unit2
• 30 Amp Series Fuse Rating
• Pre-assembled Components
• Fully Integrated and Modular Components
• Includes grounding module clamps
The FS System is capable of accommodating nearly any framed or frameless PV module currently on the market.3 Each FS System
is custom designed to meet specific structural load requirements4. Included in the FS System are the Rapid5K™ grounding clamp
specifically designed to secure the frame of a PV module to the FS System.5 In turn, the components and assemblies that comprise
an FS System form an electrically bonded unit. While individual components and structural sections will vary between designs, the
primary assemblies and installation methods will remain the same.

The FS System is evaluated for electrical bonding only. The FS System meets all IBC and ASCE requirements for structural loading; it has not been
evaluated for loading under UL 2703.
2
Installer is responsible for verifying that system meets applicable NEC and CSA standards.
3
Maximum number of modules shall not exceed system voltage.
4
Individual parts and components will vary from system to system. Please reference system specific drawings.
5
This racking system may be used to ground and/or mount a PV module complying with UL1703 only when the specific module has been evaluated for grounding
and/or mounting in compliance with the included instructions.

Foundation Post Installation
1. Survey Proposed Site
•
Review final drawing at least one week
prior to post installation. Drawing will
include information vital to the proper
installation of the foundation posts such
as the embedment depth, post-to-post
spacing, slope, rotation, and
installation tolerances.
•
Please note: Schletter does not provide
construction layouts.
•
For longer racks, intermediate stakes may
be required.
•
Posts are installed vertical to grade.
•
Installation tolerances:
Lateral post placement is ±5.0”
Total Lateral deviation of posts within an array is ±5.0”
Post height variation tolerance ±0.50”
Post verticality tolerance <2.0° in
all directions
Post rotational tolerance <±7.0°
Array tilt angular tolerance ±1.0°

2. Post Installation
•
Position each post at the respective
installation locations based on the
completed stake-out (use a forklift).
•
Position the hydraulic ram (GAYK) at the
installation location and lift the post into
position beneath the ram head.
•
Level mast of hydraulic ram.
•
Level post using a torpedo level.
•
Advance the post approximately two feet
into the subsurface then re-level the post.
•
Advance the post to the embedment
depth as shown on the final drawing.
•
Position string lines: bottom string line is
used for correct placement of post; top
string line indicates correct embedment
depth; string is run from the top of the
front post to the top of the last post.
•
When installing subsequent posts, ram
until the hammer head touches the top
string line.
Mark each post location using soil nails
with flagging
Position posts on marked locations
(use a forklift)
Ram two posts at opposite ends of array
for string line
Use string lines as guide to determine
correct placement and depth of posts
Position hydraulic ram and lift post into
position beneath ram head
Hammer head touching top string line
indicates correct depth is reached

IMPORTANT! Insert locking wedge into
the connector using a rubber mallet
immediately after installing the girders.
After locking wedge is inserted it cannot
be removed.
•
Verify that assemblies are set
in place.
•
Strut-girder connection should be torqued
to 10 ft-lbs to avoid compression of
the assembly.

4. Mount Purlins
•
Align purlins as shown on system
specific drawings.
•
Loosen upper mounting clamp
on girder.
•
Slide lip of purlin under lower
mounting clamp.
•
Verify purlins are installed perpendicular
to girder.
•
Secure purlin in place by tightening
upper mounting clamp over top lip
of purlin.
•
It may be necessary to loosen lower
mounting clamp. Mark location with
indelible marker prior to loosening.
Verify that purlin is positioned correctly before tightening mounting clamps
5. Optional Splice Connection
•
In order to form a longer section, splices
may be included to join two purlins.
•
Splices shall be located as specified on
project specific drawings.
•
Attach first purlin to girder as stated
in Step 4.
•
Insert splice piece halfway into the end
of first purlin section and secure in place
using one self-drilling screw.
•
Loosely attach second purlin section to
girder and slide over splice piece that is
connected to first purlin. Secure purlin in
place using one self-drilling screw.
•
Verify purlin is installed in correct location
as specified on the project
specific drawings.
•
Secure assembled purlin in place by
tightening all upper mounting clamps.

•
Position first module and secure
prepositioned end clamps; do not tighten.
•
Attach middle clamps to purlin on the
exposed side of first module.
•

Equipment Grounding
Many PV installations contain more than one mounting system. Such cases call for electrically bonding each of the different
manufacturers systems. Since individual racks are fully bonded units it is only necessary to connect individual racks together
from one single point to another single point.6 Only use stainless steel hardware when connecting harnesses or jumpers to the
mounting system. Take care to prevent copper wires from directly contacting aluminum surfaces as this will cause corrosion. For
this purpose, Schletter offers a bonding jumper (see page 9).
•
The PV INSTALLER of Schletter’s electrically bonded FS system must provide the components necessary for the final
connections to the grounding electrode system. Typically the installation will incorporate a grounding electrode (ground
rod), appropriately sized copper wire, rated wire connectors, and grounding lugs which are rated for this purpose. The PV
INSTALLER must follow all manufacturers’ installation literature. Installation must comply with all applicable NEC/CSA sections
including but not limited to; NEC 250 (Grounding and Bonding), NEC 690 (Solar Photovoltaic Systems), CSA 22.1 (Safety
Standard for Electrical Installations), and all other applicable state, and local electrical code requirements.
•
PV INSTALLER shall be fully responsible for all connections between Schletter’s bonded FS system and PV grounding electrode
system.
•
Equipment grounding conductors shall be no less than 14AWG (copper) or 12AWG (aluminum).
•
Equipment grounding conductors can be connected to any exposed metallic portion of rack system provided that:
a.
b.
c.
d.
connection area is sufficiently sized
dissimilar metals are not in direct contact
connection does not interfere with other components
connection is protected from damage
Safety Precautions
Follow proper installation and safety procedures at all times. Edges of parts may be sharp. Follow proper lifting procedures.
6
Schletter recommends two bonding jumpers to connect separate systems for redundancy.

FS SystemTM Ground Mount Installation Manual
Maintenance
•
Yearly inspection of system should be conducted to maintain optimal performance.
•
Visually inspect for signs of damage, wear, corrosion, or movement. Replace any affected components immediately.
•
Check for loose wiring
•
Mechanical details of the structure
•
At least 2% of bolted connections must be checked using a calibrated torque wrench. The torque wrench must have a display or be a click type torque wrench.
•
Torque wrench should be set at 50% of the intended tightening torque. Check is successful if the bolt cannot
be loosened.
•
If >10% of the checked bolted connections are loose, the check has to be increased by a factor of five.
•
If more than 10% of connections are still loose, all bolted connections much be checked.
•
Tighten to specified torques
•
Requirements per ASME B107 and AISC
•
WARNING: Risk of death by electric shock
•
Maintenance should only be performed by qualified personnel.
