Cabling and Fusing
NOTE!
Cables General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper (167°F [75°C])
conductors are recommended.
The power cable connections are situated as shown below. Dimensioning of cable cross-section must be done in accordance with the current ratings and
local legislation. See the
Specifications section
for details.
For protection of the adjustable frequency drive, the recommended fuses must be used or the unit must be with built-in fuses. Recommended fuses can
be seen in the tables of the fuse section. Always ensure that proper fusing is made according to local regulation.
The AC line input connections are fitted to the line power switch if this is included.
NOTE!
The motor cable must be shielded/armored. If an unshielded/unarmored cable is used, some EMC requirements are not complied with.
Use a shielded/armored motor cable to comply with EMC emission specifications. For more information, see
EMC specifications
in the
Design Guide
.
See section
General Specifications
for correct dimensioning of motor cable cross-section and length.
