Use splice bars only with flush installations or those that use low -profile tilt legs. A rail should always be supported by more than one footing on both sides of the splice. There should be a gap between rails, up to 3/16" at the splice connections. T -bolts should not be placed less than a distance of 1" from the end of the rail regardless of a splice. TORQUE VALUE (See Note on PG. A) Hex head socket size,5/16"- Do not exceed 10 ft -lbs. Do not use Anti -Seize. Max length of spliced rail is 40 ft. An expansion joint is required > 40 ft. I F EXPANSION JOINT USED AS THERMAL BREAK Expansion joints prevent buckling of rails due to thermal expansion. Splice bars may be used for thermal expansion joints. To create a thermal expansion joint, slide the splice bar into the footing slots of both rail lengths. Leave approxi- mately '/z" between the rail segments. Secure the splice bar with two screws on one side only. Footings (such as L -feet or standoffs) should be secured normally on both sides of the splice. No PV module or mounting hardware component should straddle the expansion joint. Modules must clearly end before the joint with mounting hardware (top mount Endclamps) terminating on that rail.T-bolts should not be placed less than a distance of 1" from the end of the rail regard- less of a splice. The next set of modules would then start after the splice with mounting hardware beginning on the next rail. Athermal break is required every 40 feet of continuously connected rail. For additional concerns on thermal breaks in your specific project, please consult a licensed structural engineer. Runs of rail less than 40 feet in length, with more than two pairs spliced together, are an acceptable installation for the SOLARMOUNT systems. Bonding connection for splice used as a thermal break. Option shown uses two Ilsco lugs -(Model No. GBL-4DBT P/N GBL-4DBT - see product data sheet for more details) and solid copper wire. o c) 0 SM SOLAR ATTACH RAIL.TO LwFEET ❑ 00 MOUNT INSTALLATION GUIDE I PAGE -------------------------------------------------------------------------------------------------------------------------------------- PLACE T BOLT INTO RAIL: Insert 3/8" T -bolt into rail at L -foot locations.
