• Observe extension cable and power strip ratings. Make sure that the total
ampere rating of all products plugged into the power strip does not exceed
80 percent of the ampere ratings limit for the power strip.
• To help protect your system from sudden, transient increases and decreases
in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
• Position system cables and power cables carefully. Route cables so that they
cannot be stepped on or tripped over. Be sure that nothing rests on any
cables.
• Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications. Always follow your local/national
wiring rules.
