Wiring in hazardous locations
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.
Figure 3 shows the wire designations for a P499
transducer used in 0.5 VDC to 4.5 VDC and 0 VDC to
10 VDC applications.
Figure 4 shows the wire designations for a P499
transducer used in 4 mA to 20 mA applications.
Figure 5 shows the wire colors for the wire terminations
in the Packard connector plug.
Figure 6 show the pins in the Packard connector socket
on the P499 transducer and the associated wire color
the pins are connected to when the Packard connector
plug is connected to the socket.
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.
