How to use

Install the F4HK14 on a standard DIN rail inside an electrical distribution enclosure. Connect the RS485 bus to the designated terminals for integration with your automation controller, and wire each load to the corresponding channel output following local electrical codes. Configure the device in the building automation system according to the controller documentation to assign switching functions and communication parameters.

Recommendations

Verify load types and total current per channel against the manufacturer's limits before connecting inductive or high inrush loads such as motors or transformers. Ensure correct RS485 polarity and termination in longer bus runs and follow applicable wiring and safety regulations during installation.
