6 Electrical Connection
8. Plug the terminal block for the AC connection in the
AC-out slot in the inverter, and tighten it with a flat-
blade screwdriver (blade width: 4 mm (
(torque: 0.3 Nm (2.65 in-lb)).
9. Ensure that the terminal block is securely in place and the screws are tightened.
10. Thread the conductors L1, L2 and N through the ferrite.
11. Strip off the conductor insulation of L1, L2 and N by 18 mm (0.71 in) each.
12. In the case of fine stranded wire, provide the conductors with a bootlace ferrule.
Connection of conductors of finely stranded wire
13.
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 (
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.
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 L1 and L2 to the terminal block in
accordance with the labeling. Insert each conductor
into the corresponding terminal point (round
opening) up to the stop. 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.
