DI
DI
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 device at least 1/2” from any uninsulated conductors.
Determine cable routing for the output 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 and relay between the sensor and the controller
(solid-state contact) and external power supply.
4. Route the conductor through the sensor’s center window and slip the assembly
into the mounting bracket.
5. Secure enclosure and reconnect power.

H800HV
INSTALLATION GUIDE
OPERATION
The H800HV 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 (setpoint) threshold plus the hysteresis value will
cause the resistance of the FET status output to change state, similar to the action of
a mechanical switch. In this model, the setpoint is xed at 750mA AC max. The status
output is suitable for connection to building controllers or other appropriate data
acquisition equipment with inputs up to 250 volts. The H800HV 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 (<250V)
• Check for amperage in monitored conductor (> 0.75A
@ 60Hz)
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 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.
