4.0 Data Center

4.1 Coordination with COR:

This project must be coordinated with building 23 security and building 23 operation manager.

The contractor shall request in writing through the COR the approval of their time table for planned service in building 23. The contractor shall request 45 days in advance an ASI (Authorized Service Interruption) from the building 23 operation manager for planned maintenance that would interrupt service. An approved ASI (Authorized Service Interruption) form (for each item of equipment and time period) (to include a primary date & time and a alternate date & time for performance) must be obtained prior to taking that item of equipment out of service. The ASI shall be submitted (45 days in advance) to the building 23 operation manager for planned maintenance that would interrupt service.

4.2 Contractor Access:

Each contractor requiring access to Building 23 must have an approved Visitor Access Request (VAR) prior to the start of work. The VAL is used to identify contractor personnel working on the contract at the site. Instructions for obtaining a Visit Authorization Request (VAR) are covered in document DM-FCIE 00 00 03.6 DISA General Requirements, Section G.2.16. The request should be sent to: DISA Visits INBOX: DISA Columbus OH EIS Mailbox Cols Visits (disa.columbus.eis.mbx.cols-visits@mail.mil).

4.3 Circuit Breaker Trip Control Power

The Digitrip 1150 trip units may be applied to either 50 or 60 Hz systems.

The Digitrip DT1150 family of trip units incorporates two microprocessors in their design. One processor is devoted totally to the task of current protection functions. This processor provides true rms current sensing for the proper coordination with the thermal characteristics of conductors and equipment. The Digitrip analyzes the secondary current signals from the circuit breaker current sensors and, when preset current levels and time delay settings are exceeded, sends an initiating trip signal to the Trip Actuator of the circuit breaker. The current sensors provide operating power to the trip unit. As current begins to flow through the circuit breaker, the sensors generate a secondary current that powers the trip unit.

The second microprocessor provides the voltage protection display, communications, metering, harmonic calculations, alarming, and auxiliary relay functions. These additional features require that auxiliary power be provided to the circuit breaker.

4.4 Trip Unit Testing (secondary injection & primary injection) A functional local test of a major portion of the trip unit’s electronic circuitry and the circuit breaker’s mechanical tripping action can be verified through the trip unit’s test receptacle.

This is accomplished using a Digitrip (DS Type) test kit that provides a secondary injection test that simulates the current sensors. A small hand-held Magnum functional test kit can also be used to check circuitry and mechanical tripping functions.

A Secondary Injection Trip Unit Test is a test that injects trip conditions by simulating the current levels but not using the current sensors. A Primary Injection Trip Unit Test is a test that injects trip conditions by using the current sensors.

4.5 Magnum Circuit Breaker’s Health (Trips, LDT, GFT, oP)

Health (applicable only to Digitrip 1150+ Rev. E or higher) The HEaLTH menu on the Digitrip 1150 front panel will provide information on the Magnum circuit breaker’s health as well as a history of the circuit breaker and circuit it is protecting. This data is useful for planning maintenance and inspection schedules.

The type of data includes the total number of all Instantaneous and Short Delay trips seen by the circuit breaker.

A second counter shows the number of overloads (LDT) and ground faults (GFT) encountered while in service. The oP count provides data on the number of close operations experienced by the circuit breaker. The internal test function will not increment the InST/SD or the LDT/GFT counters, however, there will be count values in these registers from the factory primary injection testing. Each of these three values can be zeroed by depressing the Reset pushbutton.

These counters will roll over at a value of 255. The operation counter will roll over at 65,000.

The last time the circuit breaker was operated (open or closed or tripped) is viewable with time and date displayed. Also included is the maximum temperature in degrees centigrade as seen by the Digitrip microprocessor CHip.

The capture of the data requires external trip unit power. This data, once captured, is stored in nonvolatile memory.

These features are available to Powernet communications using Digitrip firmware Rev . F or higher. Notee: Rev . F firmware permits maximum temperature to be reset.

4.6 Power Redundancy Design

Preventing a power interruption is very important. Incoming service power is provided from two different sources (labeled “Sub-A” & “Sub-B”). Each input feeder is split into two main branches.

The first main branch circuit is called “Critical Circuits” because they power the IT equipment.

The second main branch circuit is called “Essential Circuits” because they power lights, air conditioning, etc. As the power is disseminated it will travel through either “Critical Distribution Panel” circuit breakers or “Essential Distribution Panel” circuit breakers. For example the PDU’s for the IT equipment are on the “Critical Distribution Panel” circuit breakers.

5.7.2 Electrical Operation Functional Test (Circuit Breaker Preventive Maintenance) Note: Breaker accessory voltages can vary within the same breaker.

Be sure to review the accessory voltage rating before energizing as damage may occur.

This test procedure is based on the assumption that the breaker is equipped with optional shunt trip (ST), undervoltage release (UVR) and/or spring release (SR) accessories. If one accessory is missing, substitute the manual button or manual charge handle to replace the accessory’s function.

If equipped with a motor operator, the voltage is listed on the breaker nameplate.

Charge the breaker mechanism springs using the motor operator, then if equipped with a UVR, energize the UVR with the rated voltage.

Close the breaker by applying rated voltage to the spring release accessory and verify closing by noting the state of the indicating flag.

Charge the breaker mechanism springs using the motor operator. If using the motor operator, after charging, remove power to the motor operator to prevent automatic recharging.

Open the breaker by applying rated voltage to the shunt trip accessory.

Note: If UVR is not installed, proceed to step 5.14 (Trip Unit Testing [secondary injection]) With UVR energized, close the breaker using the spring release accessory. The breaker should now be closed.

Open the breaker by removing power from the UVR. The breaker should now be open.

Repeat this entire described test procedure three times.

5.7.3 Trip Unit Functional Test (Circuit Breaker Preventive Maintenance) Perform IAW with specific trip unit manual instructions.

5.9 Primary Contact Inspection (annually) (Circuit Breaker Preventive Maintenance) Note: Using the mating line of the housing halves as a reference guide will assist in this visual inspection

With the arc chutes removed, look directly down into the arc chamber, and visually inspect each primary contact structure for signs of wear and/or damage.

Use the contact wear indicator to inspect each contact. The contact wear indicator is the relative position of the individual contact fingers to a narrow, side-to-side ledge inside the arc chamber.

The ledge is actually part of the arc chamber. When the circuit breaker is closed and the contacts are in good condition, the narrow ledge is covered by the back end of each of the contact fingers. If the back end of any of the contacts are below the ledge, the contact assembly should be replaced.

Once the inspection is complete, be sure to verify the arc chutes are properly replaced as previously described in the Arc Chute Inspection procedure.

5.10 Primary Disconnect Inspection (annually) (Circuit Breaker Preventive Maintenance) For Magnum breakers with vertically mounted primary disconnects:

With breaker removed from cell, verify that vertical adapter nuts and bolts are torqued to 37–43 lb-ft For all Magnum breakers primary disconnects

5.17 Switchboard Preventive Maintenance (annually)

It is essential to maintain the equipment in satisfactory condition.

To ensure continued quality service, a systematic maintenance schedule is vital. Facility operation and local conditions vary to such an extent that the schedule must be prepared to suit the conditions. The maintenance schedule for individual devices, such as circuit breakers, meters, fusible switches, and so on, should be based upon recommendations contained in the individual instruction leaflet for each device. Inspection and test operations should be coordinated with an overall testing program to result in the least operating inconvenience and system shutdowns.

Prior to performing any maintenance on the switchboard, first de-energize the switchboard at the source. Use lockout/ tagout precautions as prescribed in OSHA, NFPA 70E, and other safety manuals.

The switchboard should be given a thorough maintenance check annually.

Exercise extreme care to prevent the equipment from being connected to the power source while tests are being conducted.

5.17.1 Switchboard Insulation Resistance Testing (Switchboard Preventive Maintenance) Prior to cleaning, perform an initial Megger or DC test of the switchboard insulation, between phases and ground. Inspect for symptoms that may indicate overheating or weakened insulation.

Record test readings. Refer to NEMA publication AB-4, Guidelines for Inspection and Preventative Maintenance of Molded-Case Circuit Breakers Used in Commercial and Industrial Application.

Prior to testing, remove all control power fusing and connections to products, which will be damaged in this test. This includes all components with control wire fusing, transient voltage surge suppression, surge protective devices, metering equipment, and so on.

Do not use AC dielectric testing.

Do not use alternating current (AC) dielectric/megger testing. Damage to components will occur.

To prevent damage to ground fault control circuits, metering circuits, surge protective device (SPD) or other control circuits, when Meggering switchboard, isolate circuits from switchboard system before beginning the Megger Operation, be sure to reconnect those circuits after Megger tests are completed.

Note: Sone ground fault circuits may not be fused; therefore, isolation of those circuits requires isconnecting wiring from busbars.

5.17.2 Switchboard Cleaning (Switchboard Preventive Maintenance) While the switchboard is de-energized, remove dust and debris from busbars, connections, supports, and enclosure surfaces. A vacuum cleaner with a long nozzle will be of assistance.

Wipe clean with a lint-free cloth. Do not use solvents to clean equipment, as damage to surfaces can occur. Should the switchboard be exposed to adverse conditions, such as airborne contaminants, more frequent inspections and cleaning may be required.

Do not use compressed air to clean or blow out debris or dust in switchboards.

Use of compressed air to clean or blow out debris in switchboards may imbed the contaminants within overcurrent devices, metering equipment, and other components.

Damage to insulation and other surface materials can occur. Do not use compressed air in cleaning.

DM-FCIE 00 00 01 Performance Work Statement for Service Contract Page 22 of 34

5.17.3 Switchboard Insulation Resistance Testing After Cleaning (Switchboard PM) After cleaning, perform a second Megger or DC test of the switchboard insulation between phases and ground.

Prior to testing, remove all control power fusing and connections to products, which will be damaged in this test. This includes all components with control wire fusing, transient voltage surge suppression, surge protective devices, metering equipment, and so on.

To prevent damage to ground fault control circuits, surge protective device (SPD), or other control circuits, when meggering switchboard, isolate circuits from switchboard system before beginning the megger operation. Be sure to reconnect those circuits after megger tests are completed.

Note: Some ground fault circuits may not be fused; therefore, isolation of those circuits requires disconnection wiring from busbars.

Do not use AC dielectric testing.

Do not use alternating current (AC) dielectric/megger testing. Damage to components will occur.

A test resulting in readings at or above 1 megaohm is satisfactory. Compare these test readings with prior readings and retain with previous testing for future comparisons. Trends of lowered insulation resistance are signs of potential problems. A Switchboard Inspection Log form should be keep to record readings.

5.17.4 Visual Inspect (Switchboard Preventive Maintenance)

Inspect Bus and Cable Connections.

1. Inspect busbar and cables for visible damage.

2. Visually inspect…
