P499 transducers are UL recognized for use in Class I, Division 2 hazardous locations. Follow these additional guidelines when wiring or servicing a P499 transducer in a hazardous location.

  • P499 Series Pressure Transducer models do not have provisions for field wiring. They are suitable for factory installation only. P499 transducers must be installed in a suitable enclosure.
  • Risk of Explosion or Fire.
  • Do not disconnect the P499 Series Electronic Pressure Transducer while its circuit is energized, unless the area is known to be nonhazardous. Disconnecting the electronic pressure transducer in a hazardous area while its electrical circuit is energized may result in an explosion or fire, and may cause serious injury or death.
  • Risque de explosion ou incendie
  • Ne pas déconnecter le P499 Series Electronic Pressure Transducer lorsque son circuit est sous tension, sauf s'il est avéré que la zone est non dangereuse. La déconnexion du electronic pressure transducer dans une zone dangereuse alors que son circuit électrique est sous tension risque d'entraîner une explosion ou un incendie et de provoquer des blessures graves, voire mortelles.
