Department of the Army US Medical Research Acquisition Activity Installation of New Additional Emergency Power Services for NEC Data Center Building 1422 at Fort Detrick in Frederick, Maryland

This project was for the Department of the Army US Medical Research Acquisition Activity at Fort Detrick for the Installation of New Additional Emergency Power Services for NEC Data Center Building 1422. The project was for installation of new additional emergency power service for new data racks at current emergency power sources at Building 1422. The work included the installation of a new Power Distribution Center Units and a new uninterruptible power supply (UPS). 

In outline the project work consisted of installing new Power Distribution Center Units and new Uninterruptible Power Supply (UPS) units, together with associated equipment. 

Equipment installation work included the installation of:

• 500 KVA GE UPS, 480 In/Out 3, phases;
• New GE batteries in cabinet with runtime of 10 minutes at 500 KVA load, for the new UPS (above);
• 800A, 480V GE Bypass Maintenance Panel with 2-breakers, 3 phase with locks, 30 KAIC rating;
• 800A, 480V, 3 phase, 60 Hertz, 30 pole panel board – square D I line;
• 150 KVA, 480-208V, three-phase, 60 Hertz Power Distribution Center with 3-42 poles. Provided 30A, 3 pole, 208 V circuit breakers and 225A main breakers for each panel;
• 225A, 480V, 3pole, 30 KAIC, thermal magnetic circuit breaker;
• 800A, 480V, 3pole, 30 KAIC, thermal magnetic circuit breaker. 

For the system input ac power was connected to the normal source ac input of the UPS module with the battery connected to the dc input of the UPS module through the battery protective device, and the ac output connected to critical loads.

Associated work included installation of related conductor and conduit, finishing work (including equipment testing, detailing, UPS start-up and use of an outside tester) and training. Extensive start-up and field testing procedures were followed including full physical inspection of received equipment, ensuring proper phase sequences by attaching a phase rotation meter to the UPS input, output and bypass buses and observing sequences, torque testing bus and battery connections, checking each electrical bus for proper phasing and identification, checking indicator lights for proper operation and color and checking the protective device over-current trip settings. The installed system was load-tested for a continuous 24-hour period by means of resistive load banks (1/2 load, ¾ load and full load for 8 hours each) and then underwent an additional full-load burn-in period of 24 continuous hours.
