Chapter 1. Important safety information

Some products are equipped with a three-pronged plug. This plug fits only
into a grounded electrical outlet. This is a safety feature. Do not defeat this
safety feature by trying to insert it into a non-grounded outlet. If you cannot
insert the plug into the outlet, contact an electrician for an approved outlet
adapter or to replace the outlet with one that enables this safety feature.
Never overload an electrical outlet. The overall system load should not
exceed 80 percent of the branch circuit rating. Consult an electrician for more
information if you have questions about power loads and branch circuit
ratings.
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.
Be sure that the power outlet provides the correct voltage and current for the
product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.
