FX Rail-Less Installation

FX SYSTEM INSTALLATION MANUAL - 9© 2018 IRONRIDGE, INC. VERSION 1.50
DESIGN GUIDELINES
Bridge FX Application:
• A bridge is required at every Cross Roof module gap location, unless the cantilever of the adjacent modules is less
than 1/3 of the maximum span.
• A bridge is required at every Trim FX union location in the Cross Roof direction. This maintains continuity in the array
through electrical bonding.
• Bridges located on the northernmost edge of an array will require thumb screws to lock them into place (refer to page
16 for detailed instructions).
Bridge FX Position:
Bridges should be centered over module gaps by using the alignment markers. If the FX Bridge position interferes with the
Mount FX location on a rafter, follow the steps below to ensure correct positioning.
1. Remove spacer from bridge.
2. Shift bridge location and swivel mount to desired position. The maximum shift of the bridge is shown on the outside
alignment markers.
3. If maximizing the allowable bridge shift isn't sufcient to avoid interference with mount, relocating the mount hole will
be required. The Shingle Rule stated above should be followed.
 If the mount hole must be placed beneath a module, the hanger nut will need to be fastened with a wrench. This may also require trimming
the shingles to prevent the mount from resting on shingles.
