8. Caution for Use
8-1 Unless it is used in accordance with the specifications ,the performance and
life may be considerably reduced . Due attention should be paid to voltage and
range for use .8-2 Avoid use the motor in the following environment.
8-2 Avoid use or save the motor in the following environment.
- High temperature and high humidity area.
- Corrosive gas such as H2S、SO2、NO2、Cl2.
- Dusty area.
8-3 Due attention must be paid to the handling and working environments because
such objects as iron powder if attracted by the motor maganent, will cause
noise, characteristic deterioration thus reducing the reliability.
8-4 Please confirm enough no problem of standards and laws and ordinances on
your cellular.
8-5 To handle the motor ,hold the motor case softly.
8-6 Rust of plate (steel) and similar edge should be OK.
8-7 Because there is error of the measurement equipment, permit the standard of
the rotational frequency to ±5 %.
