i. Ecosine Max Passive Harmonic Filters
Ecosine Max product highlights
Schaffner Ecosine Max Passive Harmonic Filters are configurable products which provide a tailored
solution to each specific problem of current harmonics mitigation of 3-phase non-linear loads.
The eight product lines, FN3470/FN3471, FN3480/FN3481, FN3472/FN3473 and FN3482/FN3483 are
applicable for low voltage 50 Hz and 60 Hz systems and they are particularly suitable for AC and DC
motor drives, battery chargers and other power electronics applications with 6-pulse front-end rectifiers.
Ecosine Max Passive Harmonic Filters technology represents an evolution of the previous generations
of passive harmonic filters and introduces following aspects of novelty:
│Ecosine Max is designed for the most demanding harmonic mitigation tasks. Ecosine
Max filters FN3470/71, FN3472/73, FN3480/81 and FN3482/83 can be applied to drives with
or without DC-link choke present, different THDi @ rated power can be achieved, as shown in
the following table. The new generation Ecosine Max filters guarantee compliance with the
toughest requirement of IEEE-519 and other stringent international power quality standards.

▪Ecosine Max demonstrates superior partial load performance. The excellent performance
of Ecosine Max filters not only reflect on mitigating harmonic current and bringing the THDi down
to 5% (diode rectifiers @ rated power), but also introducing minimum reactive power, even at
partial or no-load condition. The displacement power factor remains at cosφ >0.98 @ 50% load.
▪Most compact open frame design for cabinet integration. The upgraded version of the
Schaffner power quality simulator SchaffnerPQS3 (pqs.schaffner.com) provides the possibility
to simulate Ecosine Max Passive Harmonic Filters within an electrical system. It furthermore
offers quick and accurate performance checks.
This user manual is intended to support designers, installers, and application engineers with filter
selection, installation, application, and maintenance. It provides helpful solutions to overcome harmonics
mitigation challenges and answers frequently asked questions.
If you require additional support, please feel free to contact Schaffner or our local partner.

ii. Performance Guarantee
By selecting and installing the appropriate Ecosine Max Passive Harmonic Filters in a variable frequency
AC drive application (variable speed drive application) within our published technical specifications, we
guarantee that the input current distortion will be less than or equal to 5% THDi for standard Ecosine
Max series filters at rated power. Ecosine Max filters can also provide similar performance in other drive
applications such as constant torque, DC drives or other phase controlled rectifiers, e.g. SCR drives,
but actual THDi levels can vary by load and/or speed and/or firing angle of thyristors and therefore
cannot be guaranteed. Consult Schaffner or our local representative for assistance when applying
ecosine filters on these types of equipment.
iii. Minimum system Requirements
The guaranteed performance levels of this filter will be achieved when the following system conditions
are met:
▪Type of load: Any 3-phase equipment with front-end six-pulse diode rectifier, with or without
DC-link choke
▪Type of source: 3-phase power line without neutral
▪Line impedance: <3% (calculated for the rated filter power)
▪Line frequency: 50 Hz ±1 Hz (FN3470/71, FN3480/81), 60 Hz ±1 Hz (FN3472/73, FN3482/83)
▪Line voltage: Nominal line voltage ±10%
▪Line voltage unbalance: <1%
▪Line voltage distortion: THDv <2%
If a properly sized and installed filter fails to meet the 5% THDilevel, Schaffner will provide the necessary
application engineering support or filter replacement at no charge.
iv. Important user notice
Schaffner Ecosine Max Passive Harmonic Filters are designed for the operation on the input (grid) side
of power electronic equipment with six-pulse rectifier front-end in balanced three-phase power systems,
like typically used in AC or DC motor drives and high power DC supplies. Filter suitability for a given
application must be determined by the user on a case-by-case basis. Schaffner will not assume liability
for any consequential downtimes or damages resulting from use or application of ecosine filters outside
of their specifications. Ecosine filters are not designed for single-phase or split-phase applications.

General Installation Notes
▪Please read and follow the safety and application notes below.
▪Carefully inspect the shipping container and the product prior to
the installation. In case of visual damage, don’t install the filter and
file a claim with the freight carrier involved.
▪Filters may be heavy. Follow the instructions for lifting heavy
equipment defined by your company.
▪Use an appropriately sized threaded bolt for every mounting
hole/slot provided by the filter flange. The strength class of the bolt
must be determined by the installer, depending upon filter weight
and the material of the mounting surface.
▪Connect the filter to the protective earth (PE) terminal(s).
▪Remove all line side power, then connect the phase terminal(s)
and neutral terminal (if any) of the filter. The filter label may also
indicate LINE (grid side terminals) and LOAD (power electronics
terminals).
▪For the electrical connection of the filter terminals, apply the
torques recommended on the filter label and/or in the published
filter datasheets.
▪Cable or busbar cross sections have to be chosen in accordance
with national and international electric codes and applicable
product standards governing the equipment that will incorporate
the power quality filters and the equipment in use.
▪Some filters provide additional terminals, e.g. for over-
temperature monitoring. These features have to be properly used
before energizing the filter. If uncertain, please consult your local
Schaffner representative.
▪Active Harmonic Filters (AHF) are working with current
transformers (CTs which are a 3rd party product and which are
typically installed in electrical equipment with lethal high voltage
levels. Before attempting to install CTs read the CT installation
safety page provided by the CT manufacturer. Always consider
transformer as a part of the circuit to which it is connected, and do
not touch the leads and terminals or other parts of the transformer
unless they are known to be grounded.
▪In order to get the maximum benefit out of your power quality filter,
please also consult aditional user manuals, installation manuals,
whitepaper and other material, published in the download section
of www.schaffner.com. These additional guidelines provide
helpful hints for equipment related topics as well as technical
knowledge.
Safety Notes and Regulations
1. Label on equipment
2. Safety note category
Safety note regulations
Equipment installation, start-up, operation and
maintenance (if any) have to be carried out by
a trained and certified electrician or technician,
who is familiar with safety procedures in
electrical systems. Non-qualified persons are
not allowed to use, install, operate or maintain
PQ filters!
High voltage potentials are involved in the
operation of power quality equipment. Always
remove power before handling energized parts
of the filter, and let ample time elapse for the
capacitors to discharge to safe levels (<42V).
Residual voltages are to be measured both line
to line and line to earth.
Correct protective earthing of the equipment
must be established and the user must be
protected against supply voltage in accordance
with applicable national and local regulations.
Always practice the safety procedures defined
by your company and by applicable national
electric codes when handling, installing,
operating or maintaining electrical equipment.
Some product may include EMC filters which
may cause leakage currents to ground. Always
connect the filter to protective earth (PE) first,
then continue with the wiring of phase/neutral
terminals. When decommissioning the filter,
remove the PE connection at the end.
Using the direct OFF setting in AHF does not
disconnect the equipment from mains and is
thus not to be used as a safety switch.
Follow the general installation and
environmental condition notes closely. Ensure
that cooling slots (if any) are free from
obstructions that could inhibit efficient air
circulation. Operate the filter within its
electrical, mechanical, thermal and ambient
specifications at all times.
Power quality filters are lossy electrical
components. Parts/surfaces of the equipment
may get hot under load operating conditions.
At altitudes above 2000m, please contact
Schaffner prior to installation.
Filter suitability for a given application must
ultimately be determined by the user (the party
that is putting the filter into operation) on a case
by case basis. Schaffner will not assume
liability for any consequential downtimes or
damages resulting from use of filters outside
their specifications.
In case of uncertainty and questions please
contact your local Schaffner partner for
assistance (details per region available at
www.schaffner.com).

1.1 Distinguishing between series
The main difference between FN3470 (FN3472, FN3480 FN3482) and FN3471 (FN3473, FN3481,
FN3483) is the filter configuration, which is clearly shown in Figure 1 and Figure 2 below. FN3470,
FN3472, FN3480 and FN3482 filters contain 3 chokes, which enables them to handle the toughest
harmonic mitigation task and to achieve very high performance (5% THDi). FN3471, FN3473, FN3481
and FN3483 contain 2 chokes, they are optimal choice if the THDi requirement is lower or for drives with
DC-link choke present. The performance of all product variants at different drive setup can be found in
Table 1.

1.2 Explanation of Ecosine Max designation
Ecosine Max is part of the new generation of Schaffner passive harmonic filter. Starting from Schaffner
Ecosine Evo series, a designation system, which contains 4 sections connected with ‘-’ was introduced.
Ecosine Max series, due to its open frame design aimed at cabinet installation, is not offering all options
that could be found in Ecosine Evo series but share the same designation system with an X for
unavailable options.

|The second part of the designation ‘FN34nn-xxx-yyy-_ _ _ _ _ _ _’ indicates the motor drive
power rating, in kW for 50 Hz filters and in HP for 60 Hz filters. Please note that Ecosine Max
filters are not using current rating in the designation.
|The third part of the designation ‘FN34nn-xxx-yyy-_ _ _ _ _ _ _’ indicates the power terminal
type. For Ecosine Max all filters are equipped with busbar terminals (-99).
||The fourth part of the designation ‘FN34nn-xxx-yyy- E0XX_XX’ contains seven slots. This
designation format is shared with Ecosine Evo series, however the Ecosine Max series
doesn’t offer all the options of evo series, the only relevant option is the 5th slot, designating
the presence of a switch (S) or a trap disconnect jumper module (J) for installing a switch pro-
vided by customer themselves.
|Schaffner offers Power Quality Simulator SchaffnerPQS3 (pqs.schaffner.com) to select and
verify the most suitable Ecosine Max filter for your application.

2 Filter selection
Ecosine Max Passive Harmonic Filters need to be carefully selected and configured to enjoy maximum
benefits. Schaffner advices to verify the selection by using the Schaffner Power Quality Simulator tool
SchaffnerPQS3, available at pqs.schaffner.com.
Step 1: Grid frequency
Determine, whether the system in consideration will be operated in a 50 Hz or 60 Hz electricity grid, and
select the corresponding filter series according to the following table:
50 Hz grid
Europe, Middle East, parts of Asia, parts of South America
FN3470/FN3471
FN3480/FN3481
60 Hz grid
North and Central America, parts of Asia, parts of South America
FN3472/FN3473
FN3482/FN3483
Note: a 50 Hz filter will not provide satisfying harmonics mitigation in a 60 Hz grid, and vice versa.
Step 2: Grid voltage
Verify that the grid configuration is suitable for standard Ecosine Max Passive Harmonic Filters
according to the following table:
50 Hz grid
Nominal voltage 380–415 V AC
TN, TT, IT configuration
50 Hz grid
Nominal voltage 440–480 V AC
TN, TT, IT configuration
60 Hz grid
Nominal voltage 380–415 V AC
TN, TT, IT configuration
60 Hz grid
Nominal voltage 440–480 V AC
TN, TT, IT configuration
Step 3: Rectifier type, presence of DC-link choke in drive
Refer Table 1 for filter performance.
Step 4: Rectifier/Drive input power
The individual filter must be selected with respect to the rectifier/motor drive input power in kW
respectively in HP. It is important to match rated filter power as close as possible with the effective input
power of the rectifier/drive.
Note that if the rectifier/drive is being operated very close to its rated power, then the filter can be
selected by the motor drive’s nominal power rating. However, if the drive will be operated e.g. at only
66% of its rated power, then a smaller filter should be selected in order to get maximum harmonics
mitigation performance and the optimum in terms of cost, size, and weight. In that case the customer is
responsible to ensure that ecosine passive harmonic filter will be operated within specification. This is
particularly important in terms of overload.
