1. Disconnect and lock out power to the conductor to be monitored.
2. Choose a location for the sensor. The monitored conduc tor must pass through the
iris, and the sensor must be at least 1/2” from any conductors, as enclosure can
reach 87°C during operation (at 200A and 60°C ambient temperature). Use wire
rated at a minimum of 90°C.
3. Install the adjustable mounting bracket to the back of the enclosure using the
included screws.
4. Connect 12-24 VDC to the terminals marked Power (+) and Gnd (-).
5. Wire the mA output connections between the sensor and the controller.
6. Snap the sensor over the conductor to be monitored and clip the assembly to the
mounting bracket.

OPERATION
The EA20 Series of current-sensitive devices monitor DC current (amperage) in
the conductor passing through. These units use Pulse Reset Technology™ with
proven transducer circuitry to produce an output suitable for connection to energy
management systems, building controllers, or other appropriate data acquisition
equipment. The EA20 requires 12-24 VDC (see Specications information) to generate
its output. It comes factory calibrated at a xed span for maximum accuracy (0-100 A,
0-150 A, or 0-200 A, depending on model, see Product Identication).
NOTES
Load Currents Less Than 2 A
Wrap the monitored conductor through the center window and around the sensor
body to produce multiple turns. This increases
the current measured by the transducer.
Program equipment to account for the extra
turns, e.g., if four turns pass through the sensor
(as shown) then divide the reading by 4.
Wrapping may reduce the sensor’s accuracy.

CAUTION
RISK OF EQUIPMENT DAMAGE
• Derate the product’s maximum current for the number of turns
through the sensing window using the following formula.
Rated Max. Amps ÷ Number of Turns = Max. monitored Amps
e.g. : 100A ÷ 4 Turns = 25 Amps max. in monitored conductor
• Failure to follow these instructions can result in overheating
and permanent equipment damage.
High Load Current Monitoring
Do not expose the EA20 to continuous current levels greater than the rated maximum
current (brief current surges and fault currents should not adversely aect the EA20).
SCALING
The EA20 Series is ideal for DC current monitoring where accuracy must be
maintained in the presence of magnetic elds, current spikes, and high fault currents
(e.g. solar panels, electroplating equipment).
The EA20 Series housing oers unprecedented mounting exibility. The mounting
bracket can be attached in three dierent places. Additionally, the bracket is
compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting.

Problem Solution
The LED is o and no signal is
produced
The LED is on solid and the

Verify that supply voltage is applied to PWR (+) and
GND (-) terminals.
Verify that the unit is not attempting to monitor more
than the maximum current range.
