NEC2009 Article 100
No responsibility is assumed by Veris Industries for any consequences arising out of the
use of this material.
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
For CE compliance, conductor shall be insulated according to IEC 61010‑1:2010. The product design
provides for basic insulation only.
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 device 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.
4. Route the conductor through the sensor’s center window and slip the assembly
into the mounting bracket.
5. Secure enclosure and reconnect power.

PRODUCT OVERVIEW
TROUBLESHOOTING
The H800 is a current-sensitive switching device that monitors current (amperage) in
the conductor passing through it. A change in amperage in the monitored conducter
that crosses the switch threshold will cause the resistance of the status output to
change state, similar to the action of a mechanical switch. The threshold is fixed at
0.2 A or less. The status output is suitable for connection to building controllers or
other appropriate data acquisition equipment operating at up to 30 volts. The H800
requires no external power supply to generate its output.
Problem
No Reading at Controller
Solution
• Check for control voltage at sensor (<30 V)
• Check for amperage in monitored conductor (>0.25 A)
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.

H68xx-5A CT
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.
Program the controller to
account for the extra turns,
e.g., if four turns pass through
the sensor (as shown), then
divide the normal controller
reading by 4.
< 0.25 A (Sensor Min.)
