2. Power Requirements
System requires a clean, steady power source for reliable performance of the high frequency CPU on
the product, the quality of the power supply is even more important.
CAUTION

If the fluctuation of power supply voltage is beyond the product specifications, connect a
constant voltage transformer.

If the noise is large, connect an isolation transformer (a noise cut transformer).

Never bundle, place nearby or in parallel the power supply cable and the input /output signal
lines.

If lightning surge protection is required, connect the surge protective device (SPD).
