= Screened cable equipped with compact low-impedance

shield (NKCABLES /JAMAK, SAB/ÖZCuY-O or similar).


Note: The EMC requirements are fulfilled at factory defaults of switching frequencies (all frames).

6.1.1.2

DC supply and brake resistor cables

Vacon frequency converters are equipped with terminals for the DC supply and an optional external brake
resistor. These terminals are marked with B–, B+/R+ and R–. The DC bus connection is made to terminals
B– and B+ and the brake resistor connection to R+ and R–. Note that the DC connection is optional for
drives greater than FR8.

6.1.1.3 Control

cable

For information on control cables see Chapter 6.2.1.1 and Table 6-1.

Cable and fuse sizes, NX_2 and NX_5, FR4 to FR9

The table below shows typical cable sizes and types that can be used with the converter. The final selection
should be made according to local regulations, cable installation conditions and cable specification.
