NOTE:
SED2 Compliance with EN61000-3-12:
From September 1st, 2005 all electrical apparatus covered by the EMC
directive will have to comply with EN61000-3-12 “Limits for harmonic currents
produced by equipment connected to public low voltage systems with input
currents > 16A and =< 75 A per phase”.
Siemens variable speed drives of the product range SED2 (Micromaster 436)
fulfil the requirements of the EN 61000-3-12 (without the need for external line
reactors) regarding the THD values of Table 3 under the pre condition of Rsce
> 190. The required PWHD values will not be achieved. Due to this fact it is
recommended to apply for connection approval at the local electricity board.
The local electricity board will evaluate among many other data the content of
the 5th harmonic current and the Line Power Factor "Lambda”, which is the
ratio of active power and apparent power.
Siemens frequency inverters are optimized in design and operation
characteristics regarding energy efficiency and less interference with line
supplies.
