To minimize adverse effects from noise, twist the brown and blue wires of the power
supply cable.
Power supply type
To protect the system against erroneous voltage 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.
