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. NOTICE • • • • 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 CONTACTOR 6. Secure enclosure and reconnect power.

INSTALLATION GUIDE H606 TM 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. > 50A (Sensor max.) 240A OK! OK! A Then choose either A or B below. A.

STOP + Setpoint 1/4 For load currents less than sensor minimum rating: 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. < 1.25 A (Sensor Min.) 4x 0.5A 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.
