Certificate: 70131735 Project: 80050628 Master Contract: 266909 Date Issued: 2020-09-29 DQD 507 Rev. 2019-04-30 © 2018 CSA Group. All rights reserved. Page 2 Solarmount The system listed is designed to provide bonding/grounding, and mechanical stability for photovoltaic modules. The system is secured to the roof with the L-Foot components through the roofing material to building structure. Modules are secured to the racking system with stainless steel or aluminum mid clamps and Aluminum end clamps. The modules are bonded to the racking system with the stainless steel bonding mid clamps with piercing points. The system is grounded with 10 AWG copper wire to bonding/grounding lugs. Fire ratings of Class A with Type 1, 2, 3, or 10 for steep slope. Tested at 5 interstitial gap which allows installation at any stand -off height. The grounding of the system is intended to comply with the latest edition of the National Electrical Code, to include NEC 250 & 690. Local codes compliance is required, in addition to national codes. All grounding/bonding connections are to be torqued in accordance with the Installation Manual and the settings used during the certification testing for the current edition of the project report. The system may employ optimizers/micro-inverters and used for grounding when installed per installation instructions. UL 2703 Mechanical Load ratings: Downward Design Load (lb/ft²) 75.2 Upward Design Load (lb/ft²) 33.4 Down-Slope Load (lb/ft²) 5.0 Test Loads: Downward Load (lb/ft²)112.8 Upward Load (lb/ft²)50.13 Down-Slope Load (lb/ft²)7.5 Unirac Large Array ULA is a ground mount system using the SolarMount (SM) platform for the bonding and grounding of PV modules. ULA aluminum components merge with SM rails and installer-supplied steel pipe. The SM rail system is secured to the horizontal Pipe using the Rail Bracket components. The Rear and Front cap secures the horizontal Pipe to the vertical Pipe. The Front cap is also used to secure the Cross brace. A Slider is attached to the vertical Pipe to secure the Cross brace. The SM rails, caps, slider, rail brackets, and cross braces materials are 6105-T5 aluminum extrusion. Fasteners materials are 304 stainless steel. Horizontal and vertical pipe materials meet the minimum requirements of ASTM A53 for galvanized steel pipe in 2 and 3 diameter. The mechanical load ratings from the SM test data will be applied to the ULA model. Fire Testing is not applicable due to being a ground mount system.
