Electrical Input
Ÿ
Sine-wave input (50 to 60 Hz) is required
Ÿ
Input voltage:
– Low range:
- Minimum: 90 V ac
- Maximum: 137 V ac
- Voltage switch setting: 115 or 115 V
– High range:
- Minimum: 180 V ac
- Maximum: 265 V ac
- Voltage switch setting: 230 or 230 V
– Input kilovolt-amperes (kVA) (approximately):
- Minimum configuration as shipped: 0.08 kVA
- Maximum configuration: 0.52 kVA
Power consumption and heat output vary depending on the number and type of
optional features installed and the power-management optional features in use.
Airflow
Approximately 0.56 cubic meters per minute (20 cubic feet per minute)
Acoustical Noise-Emission Values
Ÿ
Average sound-pressure levels:
– At operator position:
- 38 dBA idle
- 43 dBA operating
– At bystander position–1 meter (3.3 ft):
- 33 dBA idle
- 37 dBA operating
Ÿ
Declared (upper limit) sound power levels:
– 4.9 bels idle
– 5.3 bels operating
These levels were measured in controlled acoustical environments according to
procedures specified by the American National Standards Institute (ANSI) S12.10
and ISO 7779, and are reported in accordance with ISO 9296.
Actual sound-pressure levels in your location might exceed the average values
stated because of room reflections and other nearby noise sources. The declared
sound power levels indicate an upper limit, below which a large number of
computers will operate.
