UPS Maintenance Agreement - NWI Base Year: DOA to 10/31/2017 +4

Five year requirement (1 base year and 4 one year options) to provide preventive maintenance coverage (PM) with battery replacement coverage (BR) as indicated on Uninterruptible Power Supplies (UPS) and Rectifiers located at various sites in the NWIHCS as listed in paragraph 2.1.

Provide all tools, parts, transportation and labor to complete the following semi-annual PM:



Electronics Preventive Maintenance: Rectifier Power Module Preventive Maintenance/Calibration of all metering and protective features. Functional testing of all transfer conditions. Inspection of online performance and equipment history. Examination of interfaces to other Power-train equipment. Visual check on batteries and battery environment. Written evaluation providing a record of equipment performance. The Vendor will perform the Preventive Maintenance at a mutually accepted date.

Battery Preventive Maintenance: VR battery system or flooded lead acid battery preventive maintenance visits during the term of the service agreement. NOTE: Due to the size and type of battery, testing and work procedures vary between battery jars above and below 100 watts per battery; work procedures may vary by UPS or related device and battery type and may be limited by safety requirements.

Performed During Semi-Annual Preventive Maintenance Visit:



Measure and Record the following:



Individual cell/battery float voltages and overall float voltage

Charger output current and voltage

AC ripple current and voltage imposed on the battery

Internal ohmic values of each cell/battery or perform a continuity test of each cell/battery

Connection Resistance of 10% of the inter cell/battery connection

Ambient temperature

Negative terminal temperature of one cell/battery per battery cabinet shelf or rack tier

Visually inspect conditions and appearance of the following:



Connection terminals inter cell/battery connectors, cables and associated hardware

Cell/battery covers, containers, and post seals

Battery racks or cabinets and associated components and hardware

Cell/battery jar or cover, noting any excessive distortion

Perform cleaning of all accessible surfaces as required



Perform the following:

Measure and record the connection resistance of 100% of the inter cell/battery connections.

Re-torque any connection where the resistance is above 20% of the average.

E. Reporting Each Preventive Maintenance Visit:



The technician(s) will issue the VA a verbal report summarizing the condition of the battery and identifying any critical issues before leaving the customer's site.

A detailed report containing all readings and observations will be sent to the VA within five business days.

Electronics (UPS Power Module, DC, PDU, Flywheel) Preventive Maintenance

The following is an outline of general checks required to be perfonned during a Preventive Maintenance. All checks should be designed to be performed during off line operation, in the bypass mode. All checks or processes may not be applicable to all equipment types or models.

Visual Inspection



Inspect all printed circuit board connections for cleanliness, swab contacts if necessary.

Inspect all power connections for signs of overheating

Inspect all subassemblies, bridges and legs for signs of component defects or stress

Inspect all DC capacitors for signs of leakage

Inspect all AC capacitors for signs of leakage

Inspect and inventory all customer-owned spare parts

Inspect for, and perform as required, any open engineering changes

Internal Operating Parameters



DC Ground Detection Offset (if applicable)

Inverter leg current average balance (if applicable)

Output filter current average phase balance

Rectifier bridge current average leg balance

AC Protection settings are checked

DC Protection settings are checked

Input and Output Frequency and Voltage Bandwidth settings are checked

Verify DC filter capacitance

i. Verify AC tank and trap filter capacitance

j. Power Supply voltages and waveforms

External Operating Parameters



System Input Voltages (all phases)

System Input Currents (all phases)

DC Charging Voltages (float and equalize), record settings, adjust to nominal

Rectifier phase on and walk up

Inverter phase on and walk up

Adjust all panel meters to measured values

System Bypass Voltages (all phases)

Manual and UV Transfer Testing, verify uninterrupted transfer waveform (if applicable)

i. Outage simulation, and battery capability testing, and verify charger current limit

j. Generator operation and interface verification (if applicable)

Environmental Parameters



UPS area ambient temperature and condition of ventilating equipment

General Cleanliness of UPS Power Module

General Cleanliness of UPS area

Replace all air filters

Clean control panel/CRT screen

Battery Cabinet Checks



General appearance of Battery System (all types)

General cleanliness of Battery System area (all types)

Inspect cells for physical abnormalities

Inspect all DC connections for abnormalities

Battery System area ambient temperature and condition of ventilating equipment

For internal batteries only, measure and record:



Overall battery float voltage

Charger output current and voltage

Negative terminal temperature of one cell/battery per battery cabinet shelf or rack tier

Monitoring System Parameters



Alarm archive review and printing

Alarm lamp test-local and remote (if applicable)

Replace all open monitor bulbs

Review Battery Test in history (if applicable)

General



Customer Consultation

Verbal Recommendations

General Observations

Following the Preventive Maintenance inspection, a written report will be provided detailing the results of the inspection, and making specific recommendations toward future remedial action.

Battery Replacement: Provide all parts, tools, labor and transportation to replace all batteries with equal or better batteries once during the duration of the agreement. Preferred year of replacement is listed in para. 2.1. under BR Year The VA reserves the right to request earlier replacement if the need is identified. It is the responsibility of the vendor to arrange delivery of the new batteries to coincide with the mutually agreed upon scheduled replacement date. Batteries shall not arrive any earlier than 2 business days before replacement. It is also the vendor's responsibility to arrange for pick-up and proper disposal of all used/old batteries within 2 business days of the replacement. All 3 NWIHCS locations have dock access to the facility, but do not have fork-lifts available. Rectifier battery replacement shall be done after 1800 hours on weekdays or on the weekend, unless the contractor can provide a system to keep the PBX/telephone system operational when they replace the batteries.



1.3. Provide all tools, parts, transportation and labor to provide Full Service Repair coverage as follows:

1.3.1. 4-Hour Response 1.3.2 Unlimited Service Calls

Free 24 Hour Tech Support

24 x 7 Contracted Service Coverage (Including Holidays)

Provide unlimited continuous effort service response within the contracted period, provide free parts, and fund all travel and labor costs.
