Approvals UL, cUL, CE (Note: Not all models
are CE compliant. See product label
for CE mark)
For products intended for the EU market, the following is
applicable to the CE compliance of the product:
The DT series comply with EN 61010-1 CAT III 600V max
measurement category. Use 24 V input power and fuse at 5
amps. Power source overvoltage category I as defi ned per EN
61010-1.
Caution! Risk of danger
Safe operation can only be guaranteed if the
transducer is used for the purpose for which it was
designed and within the limits of the technical
specifi cations When this symbol is used, it means
you must consult all documentation to understand
the nature of potential hazards and the action
required to avoid them.
Caution! Risk of electrical shock
When operating the transducer certain parts
may carry hazardous live voltage (e.g. Primary
conductor, power supply). The transducer should
not be put into operation if the installation is not
complete.

INSTRUCTIONS
DT SERIES Solid Core
0-20 or 4-20mA; 0-5 or 0-10 VDC Outputs
Quick "How To" Guide
1. Place wire to be monitored through aperture.
Ensure monitored current fl ow matches arrow
on sensor or as noted on fi gure on reverse
side.
2. Mount the sensor.
3. Connect power and output wiring.
A. Use 22-14 AWG copper wires rated 75°C
minimum. Tighten terminals to 5 in-lbs (.6
Nm) torque.
B. For current output models, ensure output
load is no more than 500 Ω.
C. For voltage output models, ensure output
load is at least 10KΩ.
4. Connect Power.
A. Connect the appropriate power supply.
