9.4 Connection to Spring-Cage Terminals
9.4.1 Connecting Power Cables to Spring-Cage Terminals
1. Insert the screwdriver into the clamping contact of the spring-cage
terminal.
2. Push the screwdriver upwards in two stages as far as the stop.
This pretensions the spring of the spring-cage terminal. The
spring-cage terminal emits an audible click when the clamping
contact is sufficiently pretensioned.
3. Insert the stripped insulated conductor into the spring-cage
terminal until it reaches the stop. When doing so, ensure that no
insulation is trapped in the terminal.
4. Press the screwdriver down and pull it out of the clamping contact.
The spring in the spring-cage terminal securely clamps the
insulated conductor.
5. Make sure that the insulated conductor is securely attached and that no insulation is trapped.
