Terminal blocks of screw-compression type are used for electrical connections.
- Open the screw terminal before inserting a wire into it for the first time. To open the screw terminal, turn the fixing screw anti-clockwise until the terminal hole is wide open (the inside of the terminal hole is surrounded by metal).
- Insert the wire and turn the fixing screw clockwise until the wire is firmly fixed.
