Care on use for "Noise Reduction Device" itself is almost needless. Only select the rated "Noise Reduction Device" not to be over the voltage and current of fundamental wave, and insert into the wire way to connect the source of noise generation and the damaged part of machinery, and "Noise Reduction Device" certainly becomes effective.

Regarding care on installation for "Noise Reduction Device", certainly pay most of it to the method of shield for the prevention of radiation. Noise freely goes convenient way, that is, from conduction to radiation or from radiation to conduction. This is a troublesome reason for the countermeasure of noise. Owing to this, in the concrete, put the leading wire connecting "Noise Reduction Device" and the damaged part in metal pipe closely or use good shield cord, or radiation noise again invades the leading wire which was specially eliminated noise by "Noise Reduction Device". Pay keen attention to this point. The shield of leading wire is indispensable for noise in MHz class that is especially strong in radiation power. And the leading wire connecting the source of generation and "Noise Reduction Device" becomes good antenna and strongly radiates noise in the air, so this case also had better be made good shield. To make this shield completely cannot be attended to too much. Generally, it is ideal to cover closely all conductive parts with the shielding goods which the impedance of high frequency becomes as low as possible. Therefore, our "Noise Reduction Device" itself is put in tight shield case. And the closed terminal box has shield cord made specially and is made to be easy in connecting with outside shielding goods.
