Steps (match images 1 → 4):
Step1. Prepare
Power off. Strip the conductor per datasheet and crimp a bootlace ferrule. Ensure the terminal block is mounted on the DIN rail and secured with end clamps.
Step2. Insert
Align the wire with the entry and push fully home. For non-ferruled fine-stranded wire, press the orange actuator with a screwdriver while inserting.
Step3. Verify
Perform a light tug test to confirm it’s locked. Route the wire and apply the terminal markers.
Step4. Release
To disconnect, press the orange actuator downward with a screwdriver while pulling the conductor out.
