Epson Perfection V500 - Manual (Page 14)

The AC adapter cord should be placed to avoid abrasions, cuts, fraying,
crimping, and kinking. Do not place objects on top of the adapter cord and
do not allow the AC adapter or the cord to be stepped on or run over. Be
particularly careful to keep the AC adapter cord straight at the end and the
point where it enters the AC adapter.
Use only the AC adapter that comes with your scanner. Using any other
adapter could cause fire, electrical shock, or injury.
The AC adapter is designed for use with the scanner with which it was
included. Do not attempt to use it with other electronic devices unless
specified.
Use only the type of power source indicated on the AC adapter’s label, and
always supply power directly from a standard domestic electrical outlet with
the AC adapter that meets the relevant local safety standards.
When connecting this product to a computer or other device with a cable,
ensure the correct orientation of the connectors. Each connector has only
one correct orientation. Inserting a connector in the wrong orientation may
damage both devices connected by the cable.
Avoid using outlets on the same circuit as photocopiers or air control
systems that regularly switch on and off.
If you use an extension cord with the scanner, make sure the total ampere
rating of the devices plugged into the extension cord does not exceed the
cord’s ampere rating. Also, make sure the total ampere rating of all devices
plugged into the electrical outlet does not exceed the electrical outlet’s
ampere rating. Do not place multiple loads on the electrical outlet.
Never disassemble, modify, or attempt to repair the AC adapter, scanner, or
scanner option by yourself except as specifically explained in the scanner’s
guides.
Do not insert objects into any opening as they may touch dangerous voltage
points or short out parts. Beware of electrical shock hazards.
Unplug the scanner and the AC adapter, and refer servicing to qualified
service personnel under the following conditions: The AC adapter or plug is
damaged; liquid has entered the scanner or the AC adapter; the scanner or
the AC adapter has been dropped or the case has been damaged; the
scanner or the AC adapter does not operate normally or exhibits a distinct
change in performance. (Do not adjust controls that are not covered by the
operating instructions.)
Unplug the scanner and the AC adapter before cleaning. Clean with a damp
cloth only. Do not use liquid or aerosol cleaners.
If you are not going to use the scanner for a long period, be sure to unplug
the AC adapter from the electrical outlet.
