Model D sensor junction box
Model DT sensor cable and
junction box
Model DT sensors can use a junction box. Model DT sensors come with
a 3-foot (1 meter) pigtail of pre-installed cable and a 3-foot (1 meter)
piece of conduit that needs to be fitted over the pre-installed cable. See
illustration on page 21.
• Slide the conduit over the pre-installed cable.
• Screw the conduit fitting end into the sensor.
The other end of the conduit can be connected to a user-supplied
junction box or directly to a transmitter.
• If the conduit is connected to a user-supplied junction box, connect the
wires to the terminals on the junction box. If possible, install wiring with
junction-box openings pointed downward, or with drip legs in the
conduits or cables, to reduce the risk of condensation or excessive
moisture in the junction box. Next, connect the 9-wire cable from the
junction box to the transmitter by following the instructions in
Connecting and shielding 9-wire cable.
• If the conduit is connected directly to a transmitter, refer to the wiring
instructions in the transmitter Quick Reference Guide.
