Compliance with various system level guidelines:
The harmonic current data in Table 2.16 to Table 2.23 are
given in accordance with IEC/EN 61000-3-12 with reference
to the Power Drive Systems product standard. They may
be used as the basis for calculation of the harmonic
currents' influence on the power supply system and for the
documentation of compliance with relevant regional
guidelines: IEEE 519 -1992; G5/4.
