WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous location, ingress protection,
and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
Use the 1/2 NPT conduit connection, shown in figure 5, for installation of field wiring.
Refer to figures 8, 9, and 10 when connecting field wiring from the control device to the transducer. Connect the
positive wire from the control device to the transducer “+” terminal and, the negative wire from the control device to
the transducer “-” terminal. Do not overtighten the terminal screws. Maximum torque is 0.45 NSm (4 lbfSin.). Connect
the transducer grounding terminal to earth ground.
Grounding terminals are provided both inside and outside the transducer housing.

WARNING
On explosion‐proof instruments, or when using natural gas as the supply medium, remove electrical power before
removing either of the housing caps in a hazardous area. Personal injury or property damage may result from fire or
explosion if power is applied to the transducer with the cap removed in a hazardous area.
