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 conduc tors.
Determine cable routing for the controller connection, allowing wiring to reach
the mounting location.
NOTICE
• 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.

INSTALLATION GUIDE
OPERATION
The H609 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 up to 120 volts. The H609 requires no external power supply to generate
its output.
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.

DANGER: 5A CTs can present hazardous voltages.
Install CTs in accordance with manufacturer's instructions.
Terminate the CT secondary before applying current.
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.
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.

TROUBLESHOOTING
Problem Solution
No Reading at Controller • Check sensor calibration (see above)
• Check for control voltage at sensor (<120V)
• Check for amperage in monitored conductor (> 1.25A)
• Assure that sensor core mating surfaces are clean and that
the core clamp is completely closed
Setpoint screw has no
stops
Both LEDs are lit Setpoint screw is too far clockwise. See solution above.
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.
