* Trip point switch positions A and B are not for use in applications where the current will fluctuate
by more than 40% (A) or 60% (B) of the nominal current. If the current will fluctuate by more
than 60%, use the H11D for on/off status (position C) only.
** The upper trip limit alarm resets when the current drops by 5% of the learned nominal current.
The lower trip limit alarm resets when the current rises by 5% of learned nominal current.
Specification Note: For CE compliance, conductor shall be insulated according to IEC 61010‑1:2001.

INSTALLATION
Disconnect power to the enclosure containing the
conductor to be monitored.
1. Determine normal operating conditions for the application, and move the slide
switch to the best setpoint range (A, B, or C) for these conditions (e.g., if normal
operation, including duct opening/closing and filter blockage is 50% of the
learned nominal current, then set the slide switch to the B range (±60%), or use
the C range (on/off status) to indicate when current falls below 2.5A at 60 Hz). For
most blower systems, the 40% (A) setting is appropriate.
2. Locate a mounting surface for the removable mounting bracket that allows the
monitored conductor to pass through the center window when it is installed and
that keeps the product at least ½” from any uninsulated conductors. Determine
cable routing for the controller connection, allowing wiring to reach the mounting
location.
3. Drill holes and mount the bracket to the chosen surface using the included screws.
4. Wire the output connections between the sensor and the controller (solid-state
contact).
5. Verify that the core mating surfaces are clean. Snap the sensor over the conductor
and clip the assembly to the mounting bracket.
6. Secure the enclosure and reconnect power.
