Apple Power Macintosh 5400 series - Manual (Page 17)

3 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 Expansion Cards and Additional Memory,” for
instructions.) If you don’t have an expansion card, continue with the next
section, “Connecting the Mouse and the 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!
