Connecting the inverter
Motor connection
●
If available, open the terminal covers of the inverter.
●
Connect the motor to terminals U2, V2 and W2.
Carefully observe the regulations for EMC-compliant wiring:
EMC-compliant connection (Page 39)
EMC-compliant installation for devices with degree of protection IP55 / UL Type 12
(Page 42)
●
Connect the protective conductor of the motor to the terminal of the inverter.
The following cable lengths are permissible:
–
Unshielded 100 m
–
Shielded:
50 m for inverters without filter
25 m for inverters with filter
You will wind additional information in Catalog D11.1 for longer cable lengths
Line supply connection
●
Connect the line supply to terminals U1/L1, V1/L2 and W1/L3.
●
Connect the protective conductor of the line supply to terminal PE of the inverter.
●
If available, close the terminal covers of the inverter.
Note
Inverters without an integrated line filter can be connected to grounded (TN, TT) and non-
grounded (IT) line supply systems. The inverters with integrated line filter are suitable
only for connection to TN line supply systems.
The permissible cable cross sections for the individual devices and power ratings are
provided in Section Technical data (Page 303).
