(R011)Power cordsEdit onlineFor your safety, IBM provides a power cord with a grounded attachment plug to use with this IBM product. To avoid electrical shock, always use the power cord and plugwith a properly grounded outlet.IBM power cords that are used in the United States and Canada are listed by Underwriter’s Laboratories (UL) and certified by the Canadian Standards Association (CSA).For units intended to be operated at 115 volts: Use a UL-listed and CSA-certified cord set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductor cord, amaximum of 15 feet in length and a parallel blade, grounding-type attachment plug rated 15 amperes, 125 volts.For units intended to be operated at 230 volts (US use): Use a UL-listed and CSA-certified cord set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductorcord, a maximum of 15 feet in length and a tandem blade, grounding-type attachment plug rated 15 amperes, 250 volts.For units intended to be operated at 230 volts (outside the US): Use a cord set with a grounding-type attachment plug. The cord set must have the appropriate safetyapprovals for the country in which the equipment is installed.IBM power cords for a specific country or region are usually available only in that country or region.GlossaryEdit onlineThis glossary defines the special terms, abbreviations, and acronyms that are used in this publication.
