Electrical:
Ÿ
Input voltage for system unit and monitor (sinewave input is required)
Low Range
Nominal: 100 V ac to 127 V ac
Maximum: 90 V ac to 132 V ac
High Range
Nominal: 200 V ac to 240 V ac
Maximum: 180 V ac to 259 V ac
Operating Requirements
All machines have two power on switches: one on the system unit and one
on the monitor (if the monitor was shipped with the model). Some high
voltage machines (180–259 V ac) might have a power cord from the
monitor to the system unit and a non-switched appliance connector.
High voltage Northern and Southern Hemisphere SVGA monitors might
come with a voltage selector switch, allowing selection of voltage of either
110 V ac or 220 V ac. This switch must be in the 220 V ac position when
the machine is plugged into a 220 V ac electrical outlet.
When the system unit is powered off for 10 seconds or more and then
powered on, the power supply generates a “power good” signal that resets
the system logic.
Note: Whether or not Rapid Resume is enabled, the on/off switch on the
system unit
does not completely power-off the power supply. Also, the
appliance outlet connector is always powered on when the system unit is
plugged into an electrical outlet. See “Rapid Resume” on page 1-17 for
more information.
A Note About Energy Saver Monitors
Ÿ
Monitors rated as “Energy Saver” models use 30 W or less when
operating in the energy-saving mode or when the system unit is
powered off.
Ÿ
To extend monitor life, the monitor should be powered off at the end of
each day.
