Cabling and Fusing
NOTE
Cables General
All cabling must comply with national and local
5 5
regulations on cable cross-sections and ambient
temperature. UL applications require 75 °C copper
conductors. 75 and 90 °C copper conductors are thermally
acceptable for the frequency converter to use in non-UL
applications.
The power cable connections are situated as shown in
Illustration 5.90. Dimensioning of cable cross section must
be done in accordance with the current ratings and local
legislation. See 3.1 General Specifications for details.
For protection of the frequency converter, the
recommended fuses must be used or the unit must be
fitted with built-in fuses. Recommended fuses can be seen
in 5.3.7 Fuses . Always ensure that proper fusing is made
according to local regulations.
The mains connection is fitted to the mains switch if
included.

The motor cable must be screened/armoured. If an
unscreened/unarmoured cable is used, some EMC
requirements are not complied with. Use a screened/
armoured motor cable to comply with EMC emission
specifications. For more information, see 5.10 EMC-correct
Installation.
