Safety information
Installation
The construction of the IBM Personal Computer provides extra protection against
the risk of electrical shock. The IBM computer has a power cord with a three-prong
plug that is required to ground metal parts. It is the responsibility of the person
installing the computer to connect it to a properly grounded electrical outlet. Seek
professional assistance before using an adapter or extension cord; these devices
could interrupt the grounding circuit.
If the computer is connected to an electrical outlet that is incorrectly connected to
the building wiring, serious electrical shock could result.
CONTINUED PROTECTION AGAINST THE RISK OF ELECTRICAL SHOCK:
For continued protection against the risk of electrical shock, follow these steps:
• Connect your computer only to an electrical outlet of the correct voltage. If you
are unsure about the voltage of the electrical outlet you are using, contact your
local power company.
• If your computer has cables other than the power cords, you must connect
them before plugging the power cords into an electrical outlet. Before removing
these cables, you must first unplug the power cords from the outlet.
• If your computer has a telephone connection, do not touch the telephone cords
when there is lightning in the area.
• Do not use or store the computer in an area where it can become wet.
• Make sure all replacement parts have characteristics identical or equivalent to
the original parts. Other parts may not have the same safety features.
• Personal injury or electrical shock may result if you undertake actions other
than those specifically described in this book. This is particularly true if you try
to service or repair the power supply, monitor, or built-in modem. Always refer
service or repairs to qualified service personnel.
