At higher altitudes, themaximum air temperatures are lower than thosespecified.Humidity:System on: 8% to 80%System off: 8% to 80%Electrical inputInput voltage:Low range:Minimum: 90 V acMaximum: 137 V acInput frequency range: 57–63 HzVoltage switch setting: 115 V acHigh range:Minimum: 180 V acMaximum: 265 V acInput frequency range: 47–53 HzVoltage switch setting: 230 V acInput kilovolt-amperes (kVA) (approximate):Minimum configuration as shipped: 0.085 kVAMaximum configuration: 0.120 kVANote: Power consumption and heat output varydepending on the number and type of optionalfeatures installed and the power-management optionalfeatures in use.Heat output (approximate) in British thermal units (Btu)per hour:Minimum configuration: 204.9 Btu/hr (60 watts)Maximum configuration: 307.3 Btu/hr (90 watts)AirflowApproximately 0.34 cubic meters per minute (12 cubicfeet per minute) maximumAcoustical noise-emission valuesAverage sound-pressure levels:At operator position:Idle: 38 dBAOperating: 43 dBAAt bystander position - 1 meter (3.3 ft):Idle: 33 dBAOperating: 37 dBADeclared (upper limit) sound-power levels:Idle: 4.8 belsOperating: 5.1 belsNote: These levels were measured in controlledacoustical environments according to the proceduresspecified by the American National Standards Institute(ANSI) S12.10 and ISO 7779 and are reported inaccordance with ISO 9296. Actual sound-pressurelevels in a given location might exceed the averagevalues stated because of room reflections and othernearby noise sources. The declared sound-powerlevels indicate an upper limit, below which a largenumber of computers will operate.Note: The computer is classified as a Class A orClass B digital device. See the Quick Reference forfurther information about this classification.Chapter 1. Overview 7
