RCD
Please note that for electrical devices with
6-pulse rectifiers at line input, like three-
phase motor drives, a RCD type B or B+ is
required. RCD with time delay are needed
to prevent unwanted fault trip at switch on
or voltage spikes. These RCD types B with
time delay have often an added letter “S”
Calculated at rated current, 440VAC and cos phi = 0.8. The exact value depends upon the efficiency of the drive, the motor and the entire application.
Maximum leakage under normal operating conditions. Note: if two phases are interrupted, worst case leakage could reach 5.4 times higher levels.

chosen RCD to guarantee functionality.
EMC/EMI filter FN 3268
Filter types from 7 to 55A are designed to
be compatible with 30mA RCDs accord-
ing to IEC 61008 and new VDE 0664-110
standards. Filters from 75 up to 180A are
designed to be compatible with 300mA
RCDs. Install the filter as close as possible
at line side of the motor drive. Regarding
correct EMC installation, please refer to
the EMC installation guide in the manual
from motor drive supplier.
Motor drive
Please set the PWM pulse pattern of the
variable speed motor drive fixed to 4kHz.
Other pulse patterns cause higher leakage
currents. Filter designs with other pulse
pattern than 4kHz are possible upon
request.

Motor cable length
Motor cable length should not exceed 30
meters for 7 up to 55A filter types to fulfill
class C1 of recommended standard EN
61800-3. For 75 up to 180A filters, cable
length should not exceed 100 meters to
fulfill class C2.
Internal EMC/EMI components
Please disconnect all internal Y-capacitors
(internal EMC/EMI filters) in the motor
drive, because these capacitors cause addi-
tional leakage currents.
Harmonics on line voltage
High voltage harmonics can create addi-
tional system leakage currents. FN 3268
filters are tested under following condi-
tions: Supply voltage is contaminated with
harmonics according to IEC 61000-2-4,
class 2, where odd-numbered multiplies of
three are limited to 30%.
