12. In the case of finely stranded wire, provide conductors L1 and L2 and, if applicable, N with a
bootlace ferrule.
13. Depending on the grid configuration, connect the conductors L1, L2 and, if applicable, N to
the connecting terminal plate for the AC connection:
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
terminal 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.
• If there is a neutral conductor, connect the
neutral conductor to the connecting terminal
plate in accordance with the labeling. Insert
the conductor into the round terminal up to
the stop.
• Connect L1 and L2 to the connecting terminal plate in accordance with the labeling.
Insert each conductor into the corresponding round terminal up to the stop.
14.
Risk of fire due to connecting the conductors to the clamping contacts
By connecting the conductors to the clamping contacts a fire can occur.
• Make sure that the conductors are
connected to the round terminals and not
to the square clamping contacts.
15. Ensure that the correct conductors are assigned to the round terminals.
16. Ensure that the conductors are plugged completely into the round terminals up to the
insulation.
