3.4.7 Power supply filters
To comply with EEC directive 89/336/EEC, an AC power filter of the appropriate type must be
connected. This can be supplied by Baldor and will ensure that the MicroFlex complies with
the CE specifications for which it has been tested. Ideally, one filter should be provided for
each MicroFlex; filters should not be shared between drives or other equipment. Table 4 lists
the appropriate filters:
MicroFlex
current
Input voltages
current
rating 230VAC, 1
Φ 230VAC, 3 Φ
1A, 3A FI0 line reactor
See sections 3.4.7.1 and 3.4.7.2.
or
FI0029A00 (see section A.1.2).
FI0018A00
6A
FI0015A02 (see section 3.4.7.2)
or
FI0029A00 (see section A.1.2).
FI0018A00
9A FI0029A00 (see section A.1.2). FI0018A03
Table 4 - Baldor filter part numbers
Maximum earth leakage from the MicroFlex is 3.4mA per phase (230V 50Hz supply). This
value does not include the earth leakage from the AC power filter, which could be much larger
(see section A.1.3).
3.4.7.1 Harmonic suppression
When operating the 1A MicroFlex (part FMH1A03...) or 3A MicroFlex (part FMH2A03...) on a
single-phase AC supply, a 13mH 4A
rms
(10A peak) line reactor is required to ensure
compliance with EN61000-3-2:2000 class A limits, when the total equipment supply load is
less than 1kW.
3.4.7.2 Reversing the filter
When using filters FI0015A00 or FI0015A02 as specified in Table 4, they must be reversed to
ensure that the MicroFlex complies with the CE specifications for which it has been tested.
The AC power supply should be connected to the filter terminals marked as the outputs, with
the MicroFlex connected to the filter terminals marked as the inputs.
WARNING : This recommendation applies only to filters FI0015A00 and FI0015A02.
Alternative filters or protection devices must be connected as specified by
the manufacturer.
