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 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 magnet , 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 ％.
