MX units with revisions prior to this will change the L-N amplitude by the set dip level but retain
mally programmed phase angle relationship. For firmware upgrades, contact
the nor
.
Note that required phase angles and amplitudes are automatically set for dips of 0, 40, 70, 80
and 100% to conform with method (A). For all other dip levels, method
(A) can be used by
programming the required phase angles to be used during the programmed dips. The amplitude
and phase angles required to obtain the correct line-to-line voltage dip per method (A) for

IEC 61000-4-34.
S

phase angle for A other than 0° are implemented by offsetting all three phases by the required
tandard dip le
of 40, 70 and 80% are embedded in the firmware and conform to table C.2 of
ince all phas
gramming on the MX series is referenced to phase A, voltage dip with a
number of degrees to get phase A at 0°. This is reflected in the actual output settings shown on
the MX versus the data in table C.2 of the IEC61000-4-34. The actual output settings are shown
in the last 3 columns.
Phase Mapping
The phase rotation on the MX series is ACB. This means phase A is mapped to L1, phase B is
mapped to L3 and phase C is mapped to L2. The required phase selection letter combination
for the required Line-to-line dip is shown in table C.2 for reference.
