Connection of conductors of finely stranded wire
To connect conductors made of finely stranded wire, each terminal must be opened.
• First insert the connector into the round terminal all the way to the lock. Then insert
a flat-blade screwdriver (blade: 3.5 mm (0.14 in)) as far as it can go into the
square clamping contact above the round terminal. This opens the lock and the
connection to the connecting terminal plate can occur. After the connection has
been made, the flat-blade screwdriver must be pulled out of the square clamping
contact.
12. Connect the conductors L and N to the
connecting terminal plate in accordance with the
labeling. Insert each conductor into the
corresponding round terminal up to the stop.
