abilities.

• Do not step on the power cords or place heavy objects on
top of them. Route the power cords and any cables away
from where people walk.
• When unplugging the power cords, do not pull on the cord
itself but pull on the plug.
• The total ampere ratings of the equipment plugged in
should not exceed the ampere rating of the cord if you are
using an extension cord. Also, the total current rating of all
equipment plugged into a single wall outlet should not
exceed the fuse rating.
