2.4 POWERING
LIBRA L-7080i is designed to use a single cable for both data transmission and power
supply. This requires that your host system can provide sufficient power on its data
port (RS232 or USB).
Power injector
Some applicable LIBRA L-7080i interface cables have a power injector to connect an
external power supply in case the host system cannot supply sufficient power for the
scanner.

NOTE

Though some cables have a power injector, this does not mean
that you must use a power supply.

For safety reasons, an automatic switch will disconnect the power
provided by the host system, as soon as a separate power
adapter is connected to the power injector.
