SED2 Compliance with EN61000-3-12:
NOTE:
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) fulfill 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.
