Power supply filters
To comply with EC directive 2004/108/EC, an AC power filter of the appropriate type
must be connected. This can be supplied by ABB and will ensure that the
MicroFlex e150 complies with the CE specifications for which it has been tested.
Ideally, one filter should be provided for each MicroFlex e150; filters should not be
shared between drives or other equipment.

Harmonic suppression
When operating the 3 A MicroFlex e150 (part E152A03...) on a single-phase AC
supply, a 13 mH, 4 A rms (10 A peak) line reactor is required to ensure compliance
with EN 61000-3-2 class A limits, when the total equipment supply load is less than
1 kW.

Reversing the filter
When using filters FI0015A00 or FI0015A02, they must be reversed to ensure that
the MicroFlex e150 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 e150 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.
