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 SUB 27031

• Certified to ULC/ORD STD C1703• Electrically Bonded Unit2

• 20 Amp Series Fuse Rating• Pre-assembled Components

• Fully Integrated and Modular Components

The FS System is capable of accommodating nearly any framed or frameless PV module currently on the market.

Each FS System is custom designed to meet specific structural load requirements3. Included in the FS System are the

Rapid2+™ Grounding Clamp specifically designed to secure the frame of a PV module to the FS System. 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.

1The 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 2703.2Installer is responsible for verifying that system meets applicable NEC and CSA standards. 3Individual parts and components will vary from system to system. Please reference system specific drawings.

FS System Product Sheet

Ground Mount System OverviewFS Mounting Kit Product Sheet Bonding Jumper Detail

For More Information

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.4 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 supplies a bonding jumper (see Page 8).

• 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) on 12AWG (aluminum).

• Equipment grounding conductors can be connected to any exposed metallic portion of rack system provided that:

a. connection area is sufficiently sizedb. disimilar metals are not in direct contact

c. connection does not interfere with other components

d. connection is protected from damage

4 Schletter recommends two bonding jumpers connect separate systems for redundancy.
