Connection of conductors of finely stranded wire
11.
To connect conductors made of finely stranded wire, each terminal point must be opened.
• First insert the connector into the terminal point all the way to the lock (round
opening). Then insert a flat-blade screwdriver (blade: 3.2 mm (
can go into the actuation shaft (rectangular opening). Hereby the lock opens and
the conductor can be placed into the terminal point as far as possible. After the
connection has been made, the flat-blade screwdriver must be pulled out of the
actuation shaft.
12.
Fire hazard due to faulty conductor connection
If the conductors are inserted into the actuation shafts (right-angled openings), a fire may
occur during inverter commissioning.
13. Connect the conductors L and N to the terminal
block in accordance with the labeling. Insert each
conductor into the corresponding terminal point
(round opening) up to the stop.
14. Ensure the conductors are plugged into the terminal
points (round openings) as far at is will go and not
into the actuation shafts (rectangular openings).
15. Ensure that the terminal points are allocated to the correct conductors.
16. Ensure that the conductors are plugged completely into the terminal points up to their
insulation.
17. Install the outlet in the desired position (e.g. next to the inverter or as switch/outlet
combination optionally at short distance from the inverter).
18. Connect the other end of the two-core cable using it directly as energy supply to the outlet.
