7. Plug the terminal block for connecting the outlet for
secure power supply operation into the SPS slot in
the inverter and tighten it with a flat-blade
screwdriver (blade width: 4mm (
5
/
32
in)).
8. Ensure that the terminal block is securely in place.
9. Strip off the conductor insulation by max. 15mm (0.59in).
10. In the case of finely stranded wire, provide the conductors L and N with a bootlace ferrule.
11.
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: 3.2mm (
1
/
8
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.
12.
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.
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.
