Notes

1.Environment
Be careful not to close the slit for thermal radiation
Avoid areas that are direct sunlight, dust, or receives radiation of heat from other.
Avoid areas that are corrosivity gas, flammable gas, libration and force.
Avoid areas that are large noise serge.

2.Precautions
However [power supply-input signal] of main product is not insulated, mature consideration at the time of the design of a control device.
Please attach a serge measure component in the side of output circuit, so that noise serge is not impressed to output terminal.

3.The stop on operation
Carry out conduct electricity inspection of an output point of contact periodically.
Since it is tended to generate a point of contact an insulation film when using it especially by minute load, cautions are required.
Be careful OUT L-OUT H may be outputted in instant, conducted electricity to main product when a setup of HIGH-LOW is changed.
A power supply is shut off, and be sure to perform a setup of SW7, SW8, and SW9.
Use a minus driver with a tip width of 2.5mm or less for operation of the vertical setup SW.
