WIRING EXAMPLES
INSTALLATION INSTRUCTIONS
INSTALLATION
1. Determine mounting location for the sensor near the
conductor to be monitored. The sensor should be located AT
LEAST 1/2” from any uninsulated conductor.
2. Sensor features a exible iris which allows the sensor to
hang on the conductor if local codes permit. A bracket is
included for screw mounting or attaching to DIN rail. For screw
mounting, drill two 3/32”pilot holes using the bracket as a
template; ensure no drill shavings are present in enclosure.
Attach bracket with screws provided.
3. Clamp sensor around INSULATED CONDUCTOR ONLY,
600VAC MAX to be monitored.
4. Snap the sensor into the mounting bracket.
5. Wire the output of the sensor to a control panel digital
input loop not to exceed 30VAC/DC wetting voltage. Tighten
terminals to 3.5 in-lb.

TECH TIPS
On low current loads, wrap sensor multiple
times to increase sensitivity
CAUTION: Do not exceed sensor
maximum current. The current
detected by the sensor will
increase 1X with each wrap.
To monitor loads greater than the current sensor
maximum rating
Use a properly rated 5A CT as shown below
CAUTION!
5A CTs can present
hazardous voltages. Install
CTs in accordance with
manufacturers instructions.
Terminate the CT secondary
wiring before energizing

OPERATION
The C-2300 output changes state whenever current above 0.35A is
present. This provides “go/no” status on loads that are not subject to
mechanical failures.
Typical on/o status applications include:
zLighting circuits
zHeater elements
zDirect drive fans (e.g. exhaust fans)
zProcess motors
