See attachment 6 Pass <br /> <br />(added by UL CRD-2022.07.21) Temperatures shall be <br />measured continuously, and all temperatures but the <br />cell temperatures are to be averaged over every 60 <br />second interval. The maximum of these averages shall <br />be documented for each thermocouple location. <br />See attachment 6 Pass <br />9.2.22 For residential use BESS, the DUT shall be covered <br />with a single layer of cheese cloth ignition indicator. Non-residential use BESS N/A <br />9.2.23 An internal fire condition in accordance with the module level test shall be created within a <br />single module in the initiating BESS unit: Pass <br /> <br />a) The position of the module shall be selected to <br />present the greatest thermal exposure to adjacent <br />modules, based on the results from the module <br />level test; and <br />Refer to TÜV SÜD Report No.: <br />5061724026506 Pass
