route the cord through the retainer clip (2), and then connect the other end to an electrical wall
outlet (3).
WARNING!
- Plug the power cord into an AC outlet that is easily accessible at all times.
- Disconnect power from the computer by unplugging the power cord from the AC outlet.
- If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded
(earthed) 3-pin outlet. Do not disable the power cord grounding pin, for example, by attaching a
2-pin adapter. The grounding pin is an important safety feature.
For your safety, do not place anything on power cords or cables. Arrange them so that no one
may accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from
the electrical outlet, grasp the cord by the plug.
