INTRODUCTION
The CurrentWatch™ EAC Series Powered
combines a current sensor and signal
conditioning electronics in a single package
for use in 120V line-voltage or 24V AC/DC
control power applications. The combination
of these devices results in a single unit with
higher accuracy, fewer individual terminations
and a space-saving simplifi ed installation.
The EAC Series family of powered current
sensors are available in split-core enclosures with 4-20 mA analog
outputs. These sensors are average responding and intended for use in
constant or on/off load applications with sinusoid waveforms.
Eaton's current sensor family encompasses a broad range of products
for cost-effective monitoring, status, and predictive maintenance.
Downtime and costly repairs can be avoided by utilizing Eaton's
products and technologies in your control systems.
QUICK INSTALL GUIDE
The below steps can be followed to quickly install a CurrentWatch™
EAC Series Powered sensor.
1. Run the wire to be monitored through the aperture
2. Mount the sensor to a surface if needed
3. Connect output wiring, using up to 12 AWG copper wires
4. Choose the correct range by positioning the Range Jumper
Effective: April 2007

INSTALLATION
Considerations for all EACP Series models...
• These sensors can be located in the same environment as motors,
contactors, heaters, pull-boxes and other electrical enclosures
• Mounting can be done in any position or hung directly on a wire
with a wire tie
• Be sure to leave at least one inch distance between sensor and
other magnetic devices
Considerations for split-core models only...
• Press the tab in the direction
shown in the diagram to the right.
• After placing the wire in the
aperture, press the hinged portion
fi rmly downward until a click is
heard and the tab pops out fully.
• Keep split-core contact areas
clean. Silicon grease is factory applied on the mating surfaces to
prevent rust and improve performance. Be careful not to allow
grit or dirt into the grease in the contact area, particularly on core
mating surfaces of split core models. Sensor operation could be
impaired if mating surfaces do not have good contact. Check
visually before closing.
RANGE SELECTION
The CurrentWatch™ EAC Series Powered sensors feature fi eld
selectable ranges. The ranges are factory calibrated, eliminating time
consuming and innacurate fi eld setting of zero or span.
Setting Range
1. Determine the normal operating amperage of your monitored
current
2. Select the range this is equal to or slightly higher than the normal
operating amperage
3. Place the Range Jumper in the appropriate position
OUTPUT WIRING
Connect control or monitoring wires to the sensor. Use up to 12 AWG
copper wire and tighten terminals to 4 inch-pounds torque.
