2.02 [MANUFACTURED UNITS]{.underline}

RETAIN 1 OF 3 PARAS BELOW TO DESCRIBE BASIC UNIT.

A. Description: Factory fabricated, in a single modular cabinet.
Automatic system operating functions include the following:

1\. Normal Conditions: Supply the load with power flowing from the
normal ac power input terminals, through the rectifier/battery charger
and inverter, with the battery connected in parallel with the rectifier
output.

> 2\. Abnormal Supply Conditions: When the normal ac supply deviates
> from specified voltage, waveform, or frequency limits, the battery
> supplies energy to maintain constant inverter output to the load.

3\. When normal power fails, energy supplied by the battery through the
inverter continues supply to the load without switching or disturbance.

> 4\. When power is restored at the normal supply terminals of the
> system, the rectifier/battery charger supplies power to the load
> through the inverter and simultaneously recharges the battery.
> Synchronize the inverter with the external source before transferring
> the load.
>
> 5\. When the battery becomes discharged and normal supply is
> available, charge the battery by the rectifier/battery charger. On
> reaching full charge, shift the rectifier/battery charger to a
> float-charge mode.

6\. When any element of the UPS system fails and power is available at
the normal supply terminals of the system, the static bypass transfer
switch switches the load to the normal source with less than
one-quarter-cycle interruption of supply.

7\. If a fault occurs in the system supplied by the UPS and current
flows in excess of the overload rating of the UPS system, the static
bypass transfer switch operates to bypass the fault current to the
normal supply circuit of the UPS system for fault clearing.

8\. When the fault has cleared, the static bypass transfer switch
returns the load to the UPS system.

B. Functional Description of Manual Operation: Manual operating
functions include the following:

MODIFY FUNCTIONAL DESCRIPTIONS IN 2 SUBPARAS BELOW TO SUIT PROJECT.

1.  Turning the inverter off causes the load to be transferred by the
    static bypasstransfer switch directly to the normal ac input source
    without interruption.

2\. Turning the inverter on causes the static bypass transfer switch to
transfer the load to the inverter.

PARA BELOW DESCRIBES FUNCTIONS THAT CAN BE EITHER OPTIONS OR STANDARD
FEATURES, DEPENDING ON MFR AND MODEL. THE FUNCTIONS ARE SOMETIMES
ACHIEVED WITH A SINGLE DEVICE. DEVICE PERMITS SYSTEM MAINTENANCE WITHOUT
INTERRUPTING POWER TO THE LOAD.

> C. Maintenance Bypass/Isolation Switch: Interlocked so UPS cannot be
> operated unless the static bypass transfer switch is in the bypass
> mode. The device has 3 settings that produce the following conditions
> without interrupting supply to the load during switching:

1\. Full Isolation: Load is supplied bypassing UPS. UPS ac supply input,
static bypass transfer switch, and UPS load terminals are completely
disconnected from external circuits.

> 2\. Maintenance Bypass: Load is supplied bypassing UPS. UPS ac supply
> terminals are energized to permit operational checking, but system
> load terminals are isolated from the load.
>
> 3\. Normal: UPS ac supply terminals are energized and the load is
> being supplied through either the static bypass transfer switch or the
> UPS rectifier and inverter.

opportunity for Owner\'s representative to observe tests.

COORDINATE BELOW WITH PART 1 OF THIS SECTION.

C. Report test results. Include the following data:

> 1\. Description of input source and output loads to be used. Describe
> actions required to simulate source load variation and various
> operating conditions and malfunctions.
>
> 2\. List of indications, parameter values, and system responses
> considered satisfactory for each test action. Include tabulation of
> actual observations during test.
>
> 3\. List of instruments and equipment required to duplicate factory
> tests in the field for those tests required to be repeated there.

[PART 3 - EXECUTION]{.underline}

3.01 [INSTALLATION]{.underline}

DELETE BELOW IF NOT REQUIRED. COORDINATE WITH DRAWINGS.

> A. Install system components on 4-inch- (100-mm-) high concrete
> housekeeping bases. Cast-in-place concrete, reinforcing, and formwork
> are specified in Division 3.
>
> B. Maintain minimum workspace at equipment according to
> manufacturer\'s written instructions and NFPA 70.
>
> C. Connections: Interconnect system components. Make connections to
> supply and load circuits according to manufacturer\'s wiring diagrams,
> unless otherwise indicated.

3.02 [IDENTIFICATION]{.underline}

> A. Identify components according to Division 16 Section \"Electrical
> Identification.\"

DELETE BELOW UNLESS BATTERIES ARE RACK MOUNTED IN THE FIELD.

1\. Identify each battery cell individually.

3.03 [FIELD QUALITY CONTROL]{.underline}

DELETE 1 OF 2 PARAS BELOW DEPENDING ON WHETHER MFR\'S REPRESENTATIVE
TESTS THE SYSTEM OR MERELY PRETESTS IT IN PREPARATION FOR INDEPENDENT
TESTING.

> A. Manufacturer\'s Field Service: Supervision of unit installation,
> connections, tests, and adjustments by a factory-authorized service
> representative. Report results in writing.
>
> B. Supervised Adjusting and Pretesting: Under supervision of a
> factory-authorized service representative, pretest system functions,
> operations, and protective features. Adjust to ensure operation
> complies with specifications. Load the system using a variable-load
> bank simulating kVA, kW, and power factor of loads for which unit is
> rated.

DELETE \"INDEPENDENT\" IN PARA BELOW IF INDEPENDENT TESTING IS NOT
REQUIRED.

> C. Tests: Perform tests listed below by an independent testing agency
> meeting the qualifications specified in the \"Quality Assurance\"
> Article. Perform tests according to the manufacturer\'s written
> instructions. Load the system using a variable-load bank to simulate
> kVA, kW, and power factor of loads for the unit\'s rating. Use
> instruments calibrated, within the previous 6 months, according to
> NIST standards.

DELETE TESTS BELOW IF FACTORY TEST RESULTS ARE ADEQUATE.

1\. Simulate malfunctions to verify protective device operation.

> 2\. Test duration of supply on emergency, low-battery voltage
> shutdown, and transfers and restoration due to normal source failure.

3\. Test harmonic content of input and output current less than 25, 50,
and 100 percent of rated loads.

4\. Test output voltage under specified transient-load conditions.

5\. Test efficiency at 50, 75, and 100 percent rated loads.

DELETE SUBPARAS BELOW IF NOT IN PROJECT.

6\. Test remote status and alarm panel functions.

7\. Test battery-monitoring system functions.

D. Retest: Correct deficiencies and retest until specified requirements
are met.

3.04 [CLEANING]{.underline}

> A. On completion of installation, inspect system components. Remove
> paint splatters and other spots, dirt, and debris. Repair scratches
> and mars of finish to match original finish. Clean components
> internally using methods and materials recommended by manufacturer.

3.05 [DEMONSTRATION]{.underline}

DELETE THIS ARTICLE IF NOT REQUIRED.

> A. Engage a factory-authorized service representative to train
> Owner\'s maintenance personnel as specified below:
>
> 1\. Train Owner\'s maintenance personnel on procedures and schedules
> related to startup and shutdown, troubleshooting, servicing, and
> preventive maintenance.
>
> 2\. Review data in the operation and maintenance manuals. Refer to
> Division 1 Section \"Contract Closeout.\"

DELETE ABOVE OR BELOW DEPENDING ON WHICH SECTION IS RETAINED IN
DIVISION 1.

> 3\. Review data in the operation and maintenance manuals. Refer to
> Division 1 Section \"Operation and Maintenance Data.\"
>
> 4\. Schedule training with Owner, through Contractor, with at least 7
> days\' advance notice.

3.06 [COMMISSIONING]{.underline}

> A. Battery Equalization: Equalize charging of battery cells according
> to manufacturer\'s written instructions. Record individual cell
> voltages.
