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.
A qualied person is one who has skills and knowledge related to the construction and
operation of this electrical equipment and the installation, and has received safety

use of this material.
DANGER
Current Monitoring
Product Overview
The H908 is a current-sensitive switching device that monitors current (amperage) in the conductor passing
through it. A change in amperage in the monitored conduc tor that crosses the switch (setpoint) 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
RoHS
Compliant
CALIBRATION section). The status output is suitable for connection to building controllers or other appropriate data
acquisition equipment operating at up to 30 volts. The H908 requires no external power supply to generate its
output.
The H908 housing oers unprecedented mounting exibility. The mounting bracket can be attached in three
dierent places. Additionally, the bracket is compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting.

Use DIN Rail Mounting clip
(Veris part number AH01) to
mount on standard DIN rail.
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 conduc tor 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 the 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 from the sensor to the controller
(solid-state contact).
4. Snap the sensor over the conductor and clip the assembly to the
mounting bracket.
5. Secure the enclosure and reconnect power.
6. Calibrate the sensor with the load running normally.
