Current Sensor 3
Publication 1414-IN019A-EN-P - July 2010
Install the Current Sensor
1. Disconnect and lock-out all power sources during installation as severe injury or death
can result from electrical shock due to contact with high voltage conductors.
Excessive current can damage the sensor.
2. Install the Split-core over the conductor to be monitored and close the sensor until it
latches, ensuring that the two halves are properly aligned.
Operation of the sensor is impaired if any dirt particles prevent good contact between
the core pieces when the device is closed. Keep the sensor clean when it is opened.
3. Mount the sensor in a suitable location by using the two mounting holes in the base of
the unit.
The conductor may be looped more than once through the sensor to multiply the
sensitivity, but this also divides the maximum currents. For example, on the 0…50 A
scale, if the conductor is looped through twice, the maximum current is 25 A.
4. Connect the output circuit to the two screw terminals by using ring or fork type
terminals.
Typical connections are shown in the wiring examples. Note polarity as indicated on the
device label. To allow field calibration, all devices have easily-accessible calibration pots.
IMPORTANT Ensure all installations are in compliance with applicable electrical codes and
that the installation is completed by qualified installers familiar with the
standards and proper safety procedures for high-voltage installation.
ATTENTION: Never rely on status indicating devices only to determine if power is
present in a conductor.
Note: Peel back label to expose adjustable pot
