Tech Brief

Simplied Grounding for Every Application

The UFO family of components eliminates the need for

separate grounding hardware by bonding solar modules

directly to IronRidge XR Rails. All system types that feature

the UFO family—Flush Mount, Tilt Mount and Ground

Mount—are fully listed to the UL 2703 standard.

UFO hardware forms secure electrical bonds with both the

module and the rail, resulting in many parallel grounding

paths throughout the system. This leads to safer and more

reliable installations.

UFO Family of Components

Universal Fastening Object (UFO)

The UFO securely bonds solar modules to XR

Rails. It comes assembled and lubricated, and

can t a wide range of module heights.

Stopper Sleeve

The Stopper Sleeve snaps

onto the UFO, converting it into

a bonded end clamp.

Bonded Splice

Each Bonded Splice uses

self-drilling screws to form

a secure connection. No

bonding strap needed.

Bonded Attachments

The bonding bolt attaches

and bonds the L-foot to the

rail. It is installed with the

same socket as the rest of the

system.

Grounding Lug

A single Grounding Lug

connects an entire row

of PV modules to the

grounding conductor.

Tech Brief System Diagram íí Approved Enphase microinverters can provide equipment grounding of IronRidge systems, eliminating the need for grounding lugs and field installed equipment ground conductors (EGC). A minimum of two microinverters mounted to the same rail and connected to the same Engage cable is required. Refer to installation manuals for additional details. UL Certification The IronRidge Flush Mount, Tilt Mount, and Ground Mount Systems have been listed to UL 2703 by Intertek Group plc.
