7.0 ATCC Electrical, Environmental and Testing Requirements

· General The requirements called out in this specification dealing with equipment evaluation are a minimum guide and shall not limit the testing and inspection to ensure compliance.

· Certification These test procedures shall be followed by the manufacturers who shall certify that they have conducted inspection and testing in accordance with this specification.

· Inspection A visual and physical inspection shall include mechanical, dimensional and assembly conformance of all parts of this specification.

· Environmental and Electrical All components, where applicable, shall properly operate within the following limits unless otherwise noted:

· Applied Line Voltage: 90 to 135 Vac

· Frequency: 60 (+/-3.0) Hertz

· Humidity: 5% to 95%

· Ambient Temperature: -34.6 °F to +165.2 °F

· Shock - Test per Specification MIL-STD-810G Method 516.6

· Vibration - per Specification MIL-STD-810G Method 514.6

· Commencement Operation All circuits, where applicable unless otherwise noted, shall commence operation at or below 90 Vac as the applied voltage is raised from 50 to 90 Vac at a rate of 2 (+/-0.5) volts / second.

· Equipment Compliance All equipment shall be unaffected by transient voltages normally experienced on commercial power lines. Where applicable, equipment purchased separately from the cabinet (which normally is resident) will be evaluated for compliance.

· Power Line Surge Protection The power line surge protection shall enable the equipment being tested to withstand (Non-destructive) and operate normally following the discharge of a 25 μF capacitor charged to ± 2,000 volts, applied directly across the incoming AC line at a rate of once every 10 seconds for a maximum of 50 occurrences per test. The unit under test will be operated at 68 °F ± 41 °F and at 120 (±12) Vac.

· Operating The equipment shall withstand (Non-destructive) and operate normally when one discharge pulse of plus or minus 300 volts is synchronously added to its incoming AC power line and moved uniformly over the full wave across 360 degrees or stay at any point of Line Cycle once every second. Peak noise power shall be 5 kilowatts with a pulse rise time of 500 ns. The unit under test will be operated at 68 °F ±41 °F and at 120 (+/-12) Vac.

· UL Requirements Equipment shall comply only with the requirements of UL Bulletin of Research No.

23, "Rain Tests of Electrical Equipment."

· Operational Conditions All equipment shall continue normal operation when subjected to the following:

· Temperature Test With the item functioning at a line voltage over Electrical Range the Device in its intended operation, the ambient temperature shall be lowered from 68 °F to 34.6 °F at a rate of not more than 64.4 °F per hour. The item shall be cycled at -34.6 °F for a minimum of 5 hours and then returned to 68 °F at the same rate.

· High Temperature Test With the item functioning at a line voltage over Electrical Range the Device in its intended operation, the ambient temperature shall be raised from 68 °F to 165.2 °F at a rate of not more than 64.4 °F per hour. The item shall be cycled at 165.2 °F for 5 hours and then returned to 68 °F at the same rate. The test shall be repeated with the line voltage at 135 Vac.

· Normal Operation All equipment shall resume normal operation following a period of at least 5 hours at -34.6 °F and less than 10 percent humidity and at least 5 hours at 165.2 °F and 22% humidity, when 90 Vac is applied to the incoming AC.

· Humidity and Ambient Temperature The relative humidity and ambient temperature values in the following table shall not be exceeded.

Ambient Temperature/ Dry Bulb (in 0F) Relative Humidity (in percent) Ambient Temperature/ Wet Bulb (in 0F)

· Quailty Control/ Final Acceptance Testing A complete QC / final test report shall be supplied with every ATCC. The test report shall indicate the name of the tester and shall be signed by a responsible manager.

· Cabinet Print Wiring diagram sheets for the cabinet shall be furnished in a weatherproof plastic pouch placed in the cabinet. Cabinet wiring diagrams shall be on non-fading.

8.0 Warranty

· ATC Cabinet and Assemblies ATCC will be covered by a minimum 1-year warranty from the date of delivery. Vendor will warrant its products to be free of defects in workmanship and/ or material. The supplier shall correct any defects at no cost to UDOT. Additionally, the supplier is responsible for shipping costs or on-site supplier technical services associated with defect repairs or defective component replacements.

· ATCC Components All ATCC components are covered under the manufacturer's standard warranty.
