Terminal diagram not shown.
This device carries mains voltage, and its terminal markings vary by model and revision. Publishing a generic AC terminal diagram here would risk you wiring live conductors from a drawing that does not match the part in your hand — so we do not print one. Use the manufacturer's own installation sheet for terminal identification.
