ANY USE OR DISCLOSURE OTHER THAN THAT WHICH RELATES TO THE CLIENT IS STRICTLY PROHIBITED. 1200 CONCORD AVENUE CONCORD, CA 94520 PREPARED FOR: RMobileT 0 10/09/25 A&E FIRM: 1355 WINDWARD CONCOURSE, SUITE 410 ALPHARETTA, GA 30005 TEL: 678-990-2338 ISSUED FOR CONSTRUCTION101/13/26 ADDRESS JDX COMMENTS203/24/26 PANEL SCHEDULE & ONE-LINE DIAGRAM PANEL SCHEDULE NOT TO SCALE PANEL SCHEDULE, TABLE 1207.1.3 & BATTERY CALCULATIONS NOT TO SCALE ESS IS LOCATED OUTDOORS ON AN EQUIPMENT PAD. ESS IS NOT LOCATED IN A HABITABLE AREA. NOTES ·DISCONNECTS (CBS) INSIDE THE B160 CABINET PER INDIVIDUAL BATTERY STRING - ALL ARE EXISTING AND TO BE RE-USED. ·ESS IS DC, NOT AC, THEREFORE IT SHOULD NOT BE INCLUDED IN THE MAINS LOAD CALCULATION. ESS/B160 IS CHARGED BY THE 6160 ALREADY IN THE LOAD TABLE. OVERVIEW OF BMS OPERATION IN BATTERY ENERGY STORAGE SYSTEMS, ONE OF THE MOST IMPORTANT HAZARD BARRIERS HELPING TO ENSURE SAFETY IS THE BATTERY MANAGEMENT SYSTEM (BMS). THE BMS PROVIDES PRIMARY THERMAL RUNAWAY PROTECTION BY ENSURING THAT THE BATTERY SYSTEM OPERATES WITHIN A SAFE RANGE OF PARAMETERS SUCH AS ITS STATE OF CHARGE AND TEMPERATURE. IN A UL 9540 LISTED BATTERY ENERGY STORAGE SYSTEM, THE BMS MONITORS, CONTROLS AND OPTIMIZES THE PERFORMANCE OF BATTERY MODULES AND DISCONNECTS THEM FROM THE SYSTEM IN THE EVENT OF ABNORMAL CONDITIONS. THE BMS ALSO PROVIDES CHARGE AND DISCHARGE MANAGEMENT OF THE BATTERIES. IN CASE OF UNDERVOLTAGE OR OVERVOLTAGE, OVER-TEMPERATURE, OR OVERCURRENT CONDITIONS, THE BMS WILL ALARM AND THEN LIMIT THE CHARGE AND DISCHARGE CURRENT OR POWER. UNDER EMERGENCY CONDITIONS, THE BMS WILL CEASE OPERATIONS AND ELECTRICALLY DISCONNECT THE BATTERY. ***NEW BATTERIES ARE TO BE INSTALLED IN THE EXISTING BATTERY CABINET. EXISTING CABINET IS NOT BEING REMOVED FOR THIS SCOPE.*** ONE-LINE DIAGRAM NOT TO SCALE BATTERY CABINET IS LOCATED ON AN OUTDOOR PAD AND IS IN COMPLIANCE WITH CEC 706.1(6) LABELING EXAMPLE ON ESS INTERNAL DISCONNECT IN ESS DC ONE-LINE DIAGRAM ELECTRICAL NOTES: 1. ALL NEW CONDUCTORS TO BE INSTALLED SHALL BE COPPER. ALL CONDUCTORS SHALL BE THHW, THWN, THWN-2, XHHW, OR XHHW-2 UNLESS NOTED OTHERWISE. 2. CONTRACTOR IS TO FIELD VERIFY ALL EXISTING ITEMS SHOWN ON THE ELECTRICAL ONE-LINE DIAGRAM AND NOTIFY THE ENGINEER OF ANY DISCREPANCIES. 3. ALL GROUNDING AND BONDING PER THE CEG. 4. THE POWER DESIGN FOR ANY ELECTRICAL POWER CHANGE IS TO BE PERFORMED BY OTHERS AND IS SHOWN HERE FOR REFERENCE PURPOSES ONLY. T-MOBILE IS SOLELY RESPONSIBLE FOR THE ELECTRICAL; POWER DESIGN SOW. 5. THE E6160AC SUPPORTS AN EXTERNAL BATTERY CABINET TO SUPPLY BACKUP DC POWER DURING AN AC MAINS OUTAGE TO THE RECTIFIERS. THE BATTERY CABLE TERMINALS AND BREAKERS ARE LOCATED AS SHOWN IN FIGURE 4. EACH BREAKER IS RATED AT 300A. FOR COPPER WIRES THAT SUPPORT THIS MUCH CURRENT, IT MUST HAVE A DIAMETER OF AT LEAST 11.684 MM. IT IS BEST TO LOCATE THE TWO CABINETS ADJACENT TO EACH OTHER TO MINIMIZE CABLE LENGTH. NOTE: THE SECOND 300A BREAKER CONNECTION BETWEEN E6160AC AND B160 SHOULD BE INSTALLED. THIS IS TO PREVENT BATTERY BREAKERS FROM TRIPPING DURING A COLD START SCENARIO WHERE INITIAL CURRENT DRAW MAY TRIP THE BATTERY BREAKER AND REQUIRE FIELD VISIT TO RESET BREAKER.
