Apple Macintosh LC 580 - Manual (Page 11)

2 Plug the other end of the power cord into a three-hole grounded outlet or power strip.
Installing an expansion card
If you purchased an expansion card for your Macintosh, install it now. (See
Appendix B, “Installing an Expansion Card,” for instructions.) If you don’t
have an expansion card, continue with the next section, “Connecting the
Mouse and Keyboard.”
WARNING This equipment is intended to be electrically grounded. Your
Macintosh is equipped with a three-wire grounding plug—a plug that
has a third (grounding) pin. This plug will fit only a grounded AC
outlet. This is a safety feature. If you are unable to insert the plug into
the outlet, contact a licensed electrician to replace the outlet with a
properly grounded outlet. Do not defeat the purpose of the grounding
plug!
