For units intended to be operated at 230 volts (outside the U.S.): Use a cord set
with a grounding-type attachment plug. The cord set should have the appropriate
safety approvals for the country in which the equipment will be installed.

IBM power cords for a specific country or region are usually available only in that
country or region.
