DI
Disconnect and lock out power to the enclosure
containing the condustor 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 ½” (13 mm) 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.
3. Wire the output connections between the sensor and the controller (solid-state
contac t).
4. Snap the sensor over the wire to be monitored and push the latch until it is
securely closed. Clip the assembly to the mounting bracket.
5. Secure the enclosure and reconnect power.

H300
INSTALLATION GUIDE
PRODUCT OVERVIEW
The H300 is a current-sensitive switching device that monitors current (amperage) in
the conductor passing through it. A change in amperage in the monitored conductor
that crosses the switch threshold causes the resistance of the FET status output
to change state, similar to the action of a mechanical switch. In this model, the
threshold is xed at 150 mA AC max. The status output is suitable for connection to
building controllers, or other appropriate data acquisition equipment operating at up
to 30 volts. The H300 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) when added range is desired for a low current
load on a high current source.

TROUBLESHOOTING
Problem Solution
No Reading at Controller • Check for control voltage at sensor (<30V)
• Check for amperage in monitored conductor (> 0.15A)
• Assure that sensor core mating surfaces are clean and
that the core clamp is completely closed.
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 through the center window. This increases the current
measured by the transducer.
Program the controller to account for the
extra turns. e.g., if four turns pass through the
sensor (as shown) divide the normal controller
reading by 4.
