JD-8 Motor Integrated Protector

Operating conditions

  • The altitude shall not exceed 2000m.
  • The ambient air temperature is -5℃~+40℃ and the average temperature within 24h shall not exceed +35℃.
  • Atmospheric condition: Relative humidity of atmosphere shall not exceed 50% at the temperature of +40℃,and higher relative humidity is allowed at lower temperature. For example, the air humidity can reach 90% at the temperature of +20℃. Regarding the condensation casually caused by humidity change, special measures shall be taken.
  • Class of pollution: Class III
  • Installation category: category III
  • The angle between the installation surface and the vertical surface shall not exceed ±5 degrees.
  • The place without obvious shake, impact and vibration shall be selected as the installation site.
  • The installation site shall conform to the following standards: explosive and dangerous medium, no gas capable of corroding and damaging insulation in the medium and less conductive dust in the medium.
  • The place with rain-proof and snow-proof equipment and a little water vapor shall be used as the installation site
