Unpack connector: Use the push-in front connector included with the module delivery.Insert wires: Strip solid or flexible wires with a ferrule (0.25 mm² to 1.5 mm²) and push directly into the square terminal hole without a screwdriver.
Release wire: Insert a small flat-head screwdriver into the round release slot above the terminal to pull a wire out.
Plug in: Slide the wired front connector into the module front until it snaps into the locking position.
Coding: Ensure the mechanical coding pins match so the wrong connector type cannot be inserted.
