Follow the instructions below for connecting the computer to a DC-input power
source.
1. Before wiring, make sure the power source is disconnected.
2. Find the terminal block in the accessory box.
3. Use the wire-stripping tool to strip a short insulation segment from the
output wires of the DC power source.

connection. See the symbols printed on the rear panel indicating the
polarities and DC-input power range in voltage.
5. Insert the exposed wires into the terminal block plugs. Only wires with
