(3) Micro-ohm or millivolt drop values shall not exceed the high levelsof the normal range as indicated in the manufacturer's publisheddata. If manufacturer's data is not available, investigate any valueswhich deviate from similar connections by more than 50 percent of thelowest value.

c. Load Test

The installed system shall be load tested for a continuous 24 hour periodby means of resistive load banks. The system shall be continuously testedat 1/2 load for 8 hours, 3/4 load for 8 hours and full load for 8 hours.Provide resistive load banks of total kW load of equipment to facilitatestartup under load conditions, and to conduct load tests described above.Instrument readings shall be recorded every half hour for the following:

(1) Input voltage (all three phases).

(2) Input current (all three phases).

(3) Input frequency.

(4) Battery voltage.

(5) Output voltage (all three phases).

(6) Output current (all three phases).

(7) Output kilowatts.

(8) Output frequency.

d. Full Load Burn In Test

The installed system shall undergo an additional full load burn-in period of24 continuous hours. If a failure occurs during the burn-in period, the testsshall be repeated. Instrument readings shall be recorded every half hour asabove. During the burn-in period, the following tests shall be performed:

(1) With the UPS carrying maximum continuous design load and suppliedfrom the normal source, switch [100 percent load][50 percent load] onand off a minimum of five times within [the burn-in period] [_____].

(2) With the UPS carrying maximum continuous design load and suppliedfrom the emergency source, repeat the switching operations describedin step a. Also, verify that the UPS module rectifier charger unit(s)go into the second-step current limit mode.

(2) With the UPS carrying maximum continuous design load and operating onbattery power, repeat the switching operations described in step aabove.

(4) Continue operation on battery power for 1 minute, then restorenormal power.

The Contractor shall furnish a high-speed dual trace oscillograph to monitorten or more cycles of the above tests at the ON and OFF transitions and twotypical steady-state periods, one shortly after the load is energized (at 30to 60 seconds) and one after operation has stabilized (at 8 to 10 minutes).Four copies of the traces shall be delivered to the Contracting Officer.

e. Battery Discharge Test

ENCLOSURE (2)


41/43

With the battery fully charged, the system shall undergo a complete batterydischarge test to full depletion and a recharge to nominal conditions.Instrument readings shall be recorded every minute during discharge for thefollowing:

(1) Battery voltage.

(2) Battery current.

(3) Output voltage (all three phases).

(4) Output current (all three phases).

(5) Output kilowatts.

(6) Output frequency.

3.2.3.2 Emergency Generator Operation

Test UPS to observe operation with emergency generator service. UPS technicalrepresentative shall verify UPS battery current limiting feature functionsproperly.

3.3 DEMONSTRATION

3.3.1 Instructing Government Personnel

Furnish the services of competent instructors to give full instruction todesignated Government personnel in the adjustment, operation, and

maintenance of the specified systems and equipment, including pertinentsafety requirements as required. Instructors shall be thoroughly familiar

with all parts of the installation and shall be trained in operating theoryas well as practical operation and maintenance work. Provide training at thefactory, and on-site.

On-site training shall include 16 hours of instruction, divided into 4 modules, over a 2 day period for 12 personnel.

Lesson plans should cover: UPS overview, UPS Operation and alarms, UPSSystem Checks, and UPS Maintenance.

Use approximately half of the time for classroom instruction. Additionaltraining with the equipment prior to actual energization is desirable.

Provide lesson plans, handouts, and training manuals to be studied one weekprior to the training. Provide a simple 10 question quiz for each session,consisting of basic homework questions such as multiple choice, true/falseand/or fill in the blank type questions.

UPS software, programs and associated files shall be provided to personnel.

When significant changes or modifications in the equipment or system are made under the terms of the contract, provide additional instructions to

acquaint the operating personnel with the changes or modifications.

Provide factory training for two personnel. Factory training shall consistof a minimum of one week at the factory plant. Transportation, and room andboard,will be paid by the government.

3.4 FINAL ADJUSTMENTS

a. Remove load bank and reconnect system for normal operation.

b. Equalize battery at 480 volts for a period of 72 hours.

c. Resume charging battery at normal float voltage of [411][_____] voltsdc.

d. Check battery connections are properly torqued to manufacturer'sspecifications. Take and record, for cell-to-cell and terminalconnections, detailed micro-ohm resistance readings. Remake connectionshaving a resistance of more than 10 percent above the average.

e. All manufacturer's data and operation manuals, which are an integral partof, and shipped with UPS, shall be delivered to Contracting Officer.

3.5 NAMEPLATE MOUNTING

Provide number, location, and letter designation of nameplates as indicated.Fasten nameplates to the device with a minimum of two sheet-metal screws ortwo rivets.

3.6 FIELD APPLIED PAINTING

Paint electrical equipment as required to match finish of adjacent surfacesor to meet the indicated or specified safety criteria. Painting shall be asspecified in Section 09 90 00 PAINTS AND COATINGS.

3.7 DISPOSAL

Upon completion of UPS installation and testing, Contractor shall removeand dispose of empty, partially full and excess acid drums, includingshipping containers, obsolete batteries, and obsolete UPS modules. Removalshall be accomplished off-base and in conformance with local laws andregulations regarding disposal of hazardous material.
