For the extension or replacement of a power supply, disconnect the power supply cable
from the power supply to be replaced. When the power supply cable is connected, part
of the circuit is energized even though the power switch is off. Therefore, the extension
or replacement of the power supply with the power supply cable connected can cause
a fire or an electric shock.
To change the power supply from a DC power supply to an AC power supply, disconnect the
power supply cable and then the ground cable. Store the removed ground cable securely.
