Connection of conductors of finely stranded wire
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: 4 mm (
5
/
32
in)) as far as it 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.
14. WARNING
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.
15. Connect the conductors to the terminal block for the AC connection:
• If there is a neutral conductor, connect the
neutral conductor to the terminal block in
accordance with the labeling. Insert the
conductor into the corresponding terminal point
(round opening) up to the stop.
