•
Follow safe electrical work practices. 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
Failure to follow these instructions will result in death or serious injury.
2. Secure with the conduit nut provided.
3. Connect load in series:
• C hoose one orange wire and connect to load side of switch.
• Choose the other orange wire and connect to load.
4. Connect status output:
• C onnect the grey wires (or brown wires for H280NC) to controller digital
input. Not polarity sensitive.

The H280 and H280NC load status switches monitor both voltage and current on
manually switched loads (e.g., lights/fans in bathrooms). This device provides status
monitoring for loads that are not, or cannot be, controlled by a building control
system. The H280 has a normally open (N.O.) output switch, while the H280NC is
normally closed (N.C.). Dual colored LEDs provide easy indication of output, with
green for normal output and red for alarm status. The H280 and H280NC require no
external power to generate the output.
