12.3.2 Mains connection
Cable protection and cable cross−section
Dimension the mains fuses and the cable cross−section of the mains cables for the mains
current resulting from the maximum supply power P
DC100%
. Additional basic conditions
such as local regulations, temperatures, etc. must also be observed. ( ¶ 467)
)
Note!
An asymmetrical DC−bus system may require higher dimensioning by factor
1.35 ... 1.5.

Mains chokes. EMC
The application of mains chokes limits and proportionally allots the current and the power
of the mains input circuits of the controllers (depending on their performance).
Only use mains chokes that are specified for DC−bus operation. ( ¶ 465)
)
Note!
Please observe that the DC−bus operation may require different mains chokes,
mains fuses and cable cross−sections than the individual operation.
Compliance with the EMC Directive may not be ensured. Check the application
of central interference suppression (collective filter) in the AC supply.
