•
•
•
Follow safe electrical work practices. See NFPA 70E in the USA, or applicable local codes.
This equipment must only be installed and serviced by qualified electrical personnel.
Read, understand and follow the instructions before installing this product.
Turn off all power supplying equipment before working on or inside the equipment.
Use a properly rated voltage sensing device to confirm power is off.
DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION
• Only install this product on insulated conductors.
Failure to follow these instructions will result in death or serious injury.

INSTALLATION
Disconnect and lock out power to the enclosure containing the
conductor to be monitored.
1. Locate a mounting surface for the removable mounting bracket that will allow
the monitored conductor to pass through the center window when it is installed
and that will keep the product at least 1/2” from any uninsulated conductors.
Determine cable routing for the controller connection, allowing wiring to reach
the mounting location.
2. Drill holes to mount the bracket to the chosen surface using the included screws.
This product is not intended for life or safety applications.
Do not install this product in hazardous or classified locations.
The installer is responsible for conformance to all applicable codes.
Mount this product inside a suitable fire and electrical enclosure.
WIRING EXAMPLE
3. Wire the output connections between the sensor and the controller (solid-state
contact) or external power supply.
4. Snap the sensor over the wire to be monitored and clip the assembly to the
mounting bracket.
5. Calibrate the sensor (see page 2) with the load running normally.
Insulated Conductor ONLY

OPERATION
CALIBRATION
The H606 is a current-sensitive switching device that monitors current (amperage) in
the conductor passing through it. A change in the conductor’s amperage that crosses
the adjustable switch threshold plus the hysteresis value causes the resistance of
the FET status output to change state, similar to the action of a mechanical switch.
In this model, the setpoint is adjustable through the action of a twenty (20) turn
potentiometer (see the CALIBRATION section). The status output is suitable for
connection to building controllers or other appropriate data acquisition equipment
operating at 5 to 30 volts. The H606 requires 5 to 30 VDC external power supply to
generate its output.
Before beginning calibration, establish normal load conditions.
NOTES
For load currents greater than sensor maximum rating:
Use a 5 Amp (H68xx series) Current Transformer (CT) as shown. This technique can be
combined with wrapping (see below) to add range for a low current load on a high
current source.

TROUBLESHOOTING
Problem
• Check sensor calibration (see above)
• Check for control voltage/current at sensor (<30V, <0.2A)
• Check for amperage in monitored conductor (> 1.25A)
• Check that at least 5 VDC are across the contacts.
• Assure that sensor core mating surfaces are clean and that
the core clamp is completely closed
Setpoint screw has no
stops
The setpoint screw has a slip-clutch at both ends of its travel to
avoid damage. Twenty turns CCW will reset the sensor to be
most sensitive. Repeat calibration above.
Both LEDs are lit
Setpoint screw is too far clockwise. See solution above.
