Never overload an electrical outlet. The overall system load should not exceed 80
percent of the branch circuit rating. If you have any questions about power loads or
branch circuit ratings, consult a qualified electrician.
Be sure that the power outlet you are using is properly wired, easily accessible and
located close to the equipment. Do not fully extend power cords in a way that will
stress the cords.
Connect and disconnect equipment from electrical outlets carefully.
Heat and product ventilation
Computers, AC power adapters and various accessories generate heat during use, as
do batteries while being charged. Always follow the basic precautions below:
• Do not leave a computer, AC power adapter or accessory in contact with the body
for extended periods of use, or while the battery is charging. Computers, AC power
adapters and accessories generate heat during normal operation; contact with the
body for extended periods can cause discomfort or, potentially, a skin burn.
• Do not charge a battery or operate your computer, AC power adapter or accessories
near flammable materials or in explosive environments.
• This product includes ventilation slots, fans and heat sinks for safe and reliable
operation. These safety features may be compromised if the product is placed on a
bed, sofa, carpet or other soft surface. Never block, cover or disable these safety
features.
