Power Cord Set Requirements
The power supplies on some computers have external power switches. The voltage select switch
feature on the computer permits it to operate from any line voltage between 100-120 or 220-240
volts AC. Power supplies on those computers that do not have external power switches are
equipped with internal switches that sense the incoming voltage and automatically switch to the
proper voltage.
The power cord set received with the computer meets the requirements for use in the country
where you purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you
use the computer.
General Requirements
The requirements listed below are applicable to all countries:
1. The power cord must be approved by an acceptable accredited agency responsible for
evaluation in the country where the power cord set will be installed.
2. The power cord set must have a minimum current capacity of 10A (7A Japan only) and a
nominal voltage rating of 125 or 250 volts AC, as required by each country’s power system.
3. The diameter of the wire must be a minimum of 0.75 mm
2
or 18AWG, and the length of the
cord must be between 1.8 m (6 feet) and 3.6 m (12 feet).
The power cord should be routed so that it is not likely to be walked on or pinched by items
placed upon it or against it. Particular attention should be paid to the plug, electrical outlet, and
the point where the cord exits from the product.
