Product Detail


Environment

① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. Keep the product in packing box and antistatic pouch in room temperature to avoid for dusts and sunlight, when customer stores the product.

② In order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after being left under the environment of an unpacking room enough. Because asituation of dew condensation occurring is changed by the environmental temperature and humidity. Evaluate the leaving time sufficiently. (Recommendation leaving time: 6 hour or more with packing state)

③ Do not operate in high magnetic field. Circuit boards may be broken down by it.

④ This product is not designed as radiation hardened.


Other

① All GNDB and VDDB terminals should be used without any non-connected lines.

② Do not disassemble a product.

③ Pack the product with original shipping package, in order to avoid any damages during transportation, when returning the product to NEC.

④ Put the spacer between inverter board and mounting surface, because of the protection for contortion and the preservation of spatial distance

When designing of the power supply, take the measures for the prevention of surge voltage.

The power supply lines (VDDB and GNDB) have large ripple voltage during luminance control of LCD lamps.

There is the possibility that the ripple voltage produces acoustic noise and signal wave noise in audio circuit and so on.

Put a capacitor (5,000 to 6,000mF) between the power supply lines (VDDB and GNDB) to reduce the noise,

if the noise occurred in the circuit.
