NOTE
To minimize adverse effects from noise, twist the brown and blue wires of
the power supply cable.
To protect the system against faulty voltages from the power supply line,
use an insulated power supply with an internal protective circuit.
The regulator on the unit is a non-insulated type.
If using a power supply device without an internal protective circuit, always
make sure power is supplied to the unit through a protective element such
as a fuse.
