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: 100 V acMaximum: 127 V acInput frequency range: 50-60 HzVoltage switch setting: 115 V acHigh range:Minimum: 200 V acMaximum: 240 V acInput frequency range: 50-60 HzVoltage switch setting: 230 V acInput kilovolt-amperes (kVA) (approximate):Minimum configuration as shipped: 0.08 kVAMaximum configuration: 0.3 kVANote: Power consumption and heat output varydepending on the number and type of optionalfeatures installed and the power-managementoptional features in use.Heat output (approximate) in British thermal units (Btu)per hour:Minimum configuration: 257 Btu/hr (75 watts)Maximum configuration: 785 Btu/hr (230 watts)AirflowApproximately 0.68 cubic meters per minute (24 cubicfeet per minute) maximumAcoustical noise-emission valuesAverage sound-pressure levels:At operator position:Idle: 28 dBAOperating: 30 dBAAt bystander position - 1 meter (3.3 ft):Idle: 26 dBAOperating: 29 dBADeclared (upper limit) sound-power levels:Idle: 4.1 belsOperating: 4.3 belsNote: These levels were measured in controlledacoustical environments according to the proceduresspecified by the American National StandardsInstitute (ANSI) S12.10 and ISO 7779 and are reportedin accordance 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.76 User Guide
