INSTALLATION
INSTRUCTIONS
Quick Start Guide
1. Remove top section of sensing ring off by
carefully prying clips away and lifting the
section vertically.
2. Mount the sensor to a DIN rail or surface
using screws in corners, if needed.
3. Place conductor inside ring and replace top
section until the clips snap firmly closed.
4. Connect output wiring.
a. Use No. 22 to 14 AWG copper wires rated
min. 75C and tighten terminals to 5-7 in-lbs.
b. Ensure output load does not exceed
product specifications.
c. Connect 24 VDC power supply and load
in series. Observe polarity.
5. Verify that the display or controller is
reading the output correctly (4mA).
6. Energize the monitored circuit.

CE
Warning! Risk of electric shock or
personal injury
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
specifications. When this symbol is used, it
means you should consult all documentation to
understand the nature of potential hazards and
the action required to avoid them.
For products intended for the EU market, the
following is applicable to the CE compliance of
the product:
The ACT/ACTR Series may comply with EN 61010-1 CAT III
300V max line-to-neutral measurement category. If insulated
cable is used for the primary circuit, the voltage rating of the
measurement category can be improved according to the
characteristics given by the cable manufacturer.
Warning! Risk of hazardous voltage
When operating the transducer, certain parts
may carry hazardous live voltage (e.g., primary
conductor, secondary terminals). The transducer
should not be put into service if the installation is
not complete.

Troubleshooting
1. Sensor has no output.
A. Power supply is not properly sized.
Check power supply voltage and current rating.
B. Polarity is reversed.
Check and correct output wiring polarity.
2. Output signal too low.
A. The range may be too high for current being monitored..
Exercise care when selecting the model range.
B. The load current is not sinusoidal.
Select an ACTR transducer for use with distorted waveforms.
C. Monitored current is below minimum required.
Loop the monitored wire several times through the aperture
until the "sensed" current rises above minimum.
Sensed Amps = (Actual Amps) x (Number of Loops).
Count loops on the inside of the aperture.
3. Sensor is always at 4mA.
Monitored load is not AC or is not on.
Check that the monitored load is AC and that it is actually
on.
4. Output signal is always at 20mA.
The range is too low for current being monitored.
Select a model with a higher range.
Description
The ACT/ACTR Series transducers combine a current
transformer and a signal conditioner into a single package.
This provides higher accuracy, lower wiring costs, easier
installation and saves valuable panel space. Both the ACT
and ACTR are available in a split core housing with a 4-20mA
output proportional to the primary AC current. ACTR series
feature a True RMS output. They are designed for application
on distorted current wave forms such as VFD outputs.
Installation
Place wire or bus bar to be monitored through the sensing
aperture.
The ACT/ACTR series transducers work in the same
environment as motors, contactors, heaters, pull-boxes and
other electrical enclosures. They can be mounted in any
position or hung directly on wires with a wire tie or snapped
directly to a 35mm DIN rail. Just leave at least one inch
distance between sensor and other magnetic devices.

Output Wiring
Connect control or monitoring wires to the sensor. Use up to
22 to 14 AWG rated minimum 75°C copper wire and tighten
terminals to 5-7 in-lbs torque. Be sure the output load does
not exceed 600 ohms with 24VDC power supply.
Connection Notes:
• Captive screw terminals

Model Range Select
The ACT/ACTR Series transducers feature factory-calibrated
ranges. This eliminates time-consuming and inaccurate field
setting of zero or span.
1. Determine the normal operating amperage of your
monitored circuit using load specifications or a test
ammeter.
2. Select the model with a range that is equal to or slightly
higher than the normal operating amperage.
