UPS Systems are not Complete Systems as many do not include the battery monitoring.

The Following pages Address an Alternate Systems Design Approach

Other Battery Cabinet Enhancements are also addressed

Cabinet Target Objectives

INDUSTRY FIRSTS

1. First Top Terminal Battery cabinet to meet the 2 Meter requirement to match UPS Heights. NOTE: Many UPS systems are 2 Meters Tall.

2. First tube frame welded battery cabinet with no sharp edges or corners.

3. First battery cabinet to be lifted from top. (Using Load spreaders).

4. CFD engineered cool down of 1.5 hours after major discharge event of 30 minutes or more.

5. First cabinet to use laminated bus bars to simplify tier to tier cabling.

6. First cabinet to use best in class 4/0 ~6,000 strand cables with fusion lugs. Best Flexure, Lowest IR Drop in the industry.

7. Highest repeatable tolerance cabinet in the industry using engineered weldment fixtures.

8. Achieved $2,200 per Cabinet Price Objective in Quantity.

9. Preemptive battery failure monitoring.

10. Cable pass through directly into UPS system with no Conduits. Fastest install times.

11. Breaker access through front door.

12. Passed GR-63 Issue 4 Zone 4 Seismic on the first pass.4/07/15Cabinet at a Glance
