1.0 OVERVIEW OF FX SYSTEM
The IronRidge FX Mounting System is a rail-less system for mounting solar modules on
composition shingle pitched roofs. At the heart of the system is the Mount FX, which both
supports and electrically bonds modules. The innovative grip design of the Mount eliminates
the need for traditional clamps and associated steps to tighten them as well as setting a mount
and gripping a module, speeding up installs. Integrated bonding features throughout the system
ensure redundant bonding paths within the array – both N-S and E-W directions – without any
additional hardware and meets the highest levels of UL 2703. Like all IronRidge products, the
FX System can support extreme wind and snow loads and uses only aluminum and stainless
steel components to ensure complete corrosion resistance.
The following images show the core FX system components.

2.1 Environmental Considerations
Wind/Snow Loads
Because PV is installed outdoors, your system will need to withstand regional wind and snow
loads. Contact your local building authority to obtain the values for your site location.
