i. Ecosine evo passive harmonic filter Ecosine evo product highlights
Schaffner ecosine evo 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, FN 3440/FN 3441, FN 3450/FN 3451, FN 3442/FN 3443 and FN 3452/FN 3453 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 evo passive harmonic filter technology represents an evolution of the previous generations of passive harmonic filters and introduces following aspects of novelty:
| Ecosine evo is designed for the most demanding harmonic mitigation tasks. Ecosine evo filters
FN 3440, FN 3450, FN 3442 and FN 3452 are designed for three-phase diode and thyristor rectifier, to achieve THID 5% even without DC-link choke included in the drive. If there is 8% DC link choke present in the drive, ecosine evo filters FN 3441, FN 3451, FN 3443 and FN 3453 help to achieve 5% THID @ rated power. The new generation ecosine evo filters guarantee compliance with the toughest requirement of IEEE-519 and other stringent international power quality standards.
| Ecosine evo demonstrates superior partial load performance. The excellent performance of
ecosine evo filters not only reflects on mitigating harmonic current and bringing the THID 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.
| The modular concept of ecosine evo offers optimal tailored solution. Ecosine evo are
configurable filters, optional modules includes fan with aux. power supply, fan without aux. power supply, trap disconnect jumper and RC damper modules. Optimal solutions can be achieved by merely plugging a new module according to different installation conditions and drive setups.
| Most compact design, robust, reliable and ready to use. | The Schaffner ecosine evo product configurator (myecosine.com
) supports customers in evaluating
the best suited filter type.
| The upgraded version of the Schaffner power quality simulator SchaffnerPQS3 (pqs.schaffner.com)
provides the possibility to simulate ecosine evo 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 your local Schaffner representative.

ii. Performance Guarantee
Selecting and installing the appropriate ecosine evo passive harmonic filter 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% THID for standard ecosine evo series filters at rated power. Ecosine evo 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 THID levels can vary by load and/or speed and/or firing angle of thyristors and therefore cannot be guaranteed. Consult your local Schaffner representative for assistance when applying ecosine filters on these types of equipment.
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-p hase equ ipment with front-end six-pulse diode rectifier, with
(FN 3441/43/51/53) or without DC-link choke (FN 3440/42/50/52).
| Type of source: 3-phase power line without neutral | Line impedance: <3% (calculated for the rated filter power) | Line frequency: 50 Hz ±1 Hz (FN 3440/41, FN 3450/51), 60 Hz ±1 Hz (FN 3442/43, FN 3452/53) | Line voltage: Nominal line voltage ±10% | Line voltage unbalance: <1% | Line voltage distortion: THVD <2%
If a properly sized and installed filter fails to meet the 5% THID level, Schaffner will provide thenecessary application engineering support or filter replacement at no charge.
iii. Important user notice
Schaffner ecosine evo harmonic filters are designed for the operation on the input (grid) side of power electronic equipment with six-pulse rectifier front-ends 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 app licat io ns.

1. Ecosine evo passive harmonic filter designation
1.1 Distinguishing between FN 3440/FN 3441, FN 3450/FN 3451, FN 3442/FN 3443 and FN 3452/FN 3453
Before going into the details of the designation, it is important to be aware of the difference between FN 3440 and FN 3441, FN 3450 and FN 3451, FN 3442 and FN 3443, FN 3452 and FN 3453. FN 3440, FN 3450, FN 3442 and FN 3452 are used for motor drives without dc-link choke. They are similar to FN 3441, FN 3451, FN 3443 and FN 3453 except there is one choke less in FN 3441, FN 3451, FN 3443 and FN 3453 series as they are meant to be used for motor drives with dc-link choke (8%) included. In other w ords, there are three chokes (line choke, trap choke and load choke) included in filter series FN 3440, FN 3450, FN 3442 and FN 3452, whereas there are only two chokes (line choke, trap choke) included in filter series FN 3441, FN 3451 FN 3443 and FN 3453 series.
By distinguishing between FN 3440, (FN 3450, FN 3442, FN 3452) as well as FN 3441 (FN 3451, FN 3443, FN 3453) Schaffner is able to provide optimized solutions for different drive types:
| If there is no DC-link choke present in the motor drive, FN 3440, FN 3450, FN 344 2, FN 3452 filter
series help to reduce THID to 5% @ rated power.
| If there is a minimum 8% DC-link choke present in the motor drive, FN 3441, FN 3451, FN 3443, FN
3453 filter series reduce THID to 5% @ rated power
In case you have difficulties to decide for the right filter, please contact your local Schaffner representative for support.

2. Filter selection
Ecosine evo passive harmonic filters need to be carefully selected and configured in order to enjoy maximum benefits. Besides the enclosed selection tables and the product datasheets included in the online configurator (myecosine.com
), Schaffer advices to verify the selection by using the Schaffner Power Quality Simulator tool
SchaffnerPQS3, avai lab le 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
FN 3440/FN 3441
FN 3450/FN 3451
60
Hz grid North and Central America, parts of Asia, parts of South America FN 3442/FN 3443
FN 3452/FN 3453
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 evo 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 440–500 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
FN 3440
FN 3441
FN 3450
FN 3451
FN3442
FN3443
FN 3452
FN 3453
For 6
-pulse diode rectifier
without DC-link choke
For 6
-pulse diode rectifier
with 8% DC-link choke
For SCR rectifier
Note: For 6-pulse diode rectifier with DC-link choke smaller than 8%, it is recommended to choose FN 3440, FN 3450, FN 3442 or FN 3452 if 5% THID is required.
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
Page 12

ecosine passive harmonic filter will be operated within specification. This is particular important in terms of overload.
Please refer to the following examples:
Example 1:
Power line rating: 400 V, 50 Hz Drive rating: 380–500 V, 50–60 Hz, 15 kW, 22.5 A, B6-diode rectifier without DC-link choke Planned rectifier/drive input real power: 15kW (100% of drive rating)

Recommended filter according to the filter selection table FN 3450: Type FN 3450-15-113
Example 5:
Power line rating: 400 V, 50 Hz Drive rating: 380–500 V, 50–60 Hz, 15 kW, 22.5 A, diode rectifier Planned rectifier/drive input real power: 10 kW (66% of drive rating)
Recommended filter according to the filter selection table FN 3440: Type FN 3440-11-113
Example 6:
Power line rating: 480 V, 60 Hz Drive rating: 380–500 V, 50–60 Hz, 30 H P, 41 A, diode rectifier Planned rectifier/drive input real power: 30 HP (100% of drive rating)
Recommended filter according to the filter selection table FN 3452: Type FN 3452-30-113
Oversizing of passive har m onic filters is not recommended because of the inherent lower harmonic mitigation performance at partial load as well as higher cost, size, and weight.
Please refer to Table 2 - Table 9 to select suitable filters.

3.5 Additional electrical specifications
Ecosine evo passive harmonic filters general electrical specifications refer to operating altitudes up to 2000m a.s.l. (6600ft).
Operation between 2000m and 4000m (6600ft and 13123ft) requires a derating for current and clearance according to IEC 60664-1 (table A.2), hereafter enclosed:
Table 16 Altitude correction factors
Remark: Do not use ecosine evo passive harmonic filters in altitudes above 4000m without consulting Schaffner first.
3.6 Cooling requirement
Inlet air flow requirements for each frame size are listed in Table 17. Please notice that the filters with frame size A, B and C do not require air cooling. For frame sizes D to H, the required inlet air flow should be fulfilled, either by including the optional Fan module or by providing sufficient external air flow.
Table 17 Inlet air flow required for cooling
Remark: External air flow is required for the cooling at filter’s inlet as defined in the table only for filters without embedded ventilati on.

7. Filter application
Ecosine evo passive harmonic filters are designed to mitigate harmonic current of non-linear loads, in particular of three-phase diode-type rectifiers. Contrary to “bus-applied or PCC” filters, which are being installed e.g. at the main feeder, they are specifically designed to be used with either an individual non-linear load, or with a group of non-linear loads.
One advantage of load-applied filtering is the fact that the upstream power (relative to the harmonic filter) is clean, i.e. unloaded by the harmonics. This can be of vital importance when the same power bus supplies both motor drives and sensitive loads. Ecosine evo passive harmonic filters are also suitable for paralleling lower power non-linear loads on a higher power harmonic filter to improve overall system economy. In this case the total expected load power of all connected drives must match the filter.
If the expected input power exceeds the rating of the largest available filter, and a custom solution is not desired, then two or more filters can be wired in parallel. In this mode of operation, it is recommended to use filters with equal power ratings to ensure proper current sharing.

8. Filter installation
Please follow the simple steps below to ensure a safe and reliable filter function for many years. Please do also always follow the general safety and installation guidelines provided within this document as well as relevant local, national or international standards that are applicable. Please note that the following installation steps are applicable for both IP 00 and IP 20 enclosure.
Step 1: Visual inspection
All Schaffner ecosine evo passive harmonic filters have undergone rigorous testing before they left our ISO 9001:2008 certified factories. They are packaged with great care in a sturdy container for international shipment.
However, carefully inspect the shipping container for damage that may have occurred in transit. Then unpack the filter and carefully inspect for any signs of damage. Keep the shipping container for future transportation of the filter.
In the case of damage, please file a claim with the freight forwarder involved immediatel y and contact your local Schaffner partner for support. Under no circumstances install and energize a filte r w ith v is ib le transportation damage.
If the filter is not going to be put in service upon receipt, store within the original container in a clean, dry location, free of dust and chemicals and with respect to named temperature limits, see section 3.2.
Step 2: Mounting
Ecosine evo passive harmonic filters are best installed as close as possible to the non-linear load. Ideally they are mounted next to the rectifier or motor drive inside the electrical cabinet or control room.
All ecosine evo pass i ve har monic filters FN 3440/FN 3441, FN 3450/FN 3451, FN 3442/FN 3443, FN 3452/FN 3453 are designed for wall-mounting insta ll at ion.
Important:
In order to ensure sufficient air flow, keep a clearance of min.150mm above and below the filter to walls or other components.
Additional work to access the device, caused by not respected clearance distances, will be accounted separately.
It must be ensured that the environmental temperature is kept below 45°C with appropriate thermal management (e.g. cabinet cooling). Filter operation in environments with higher temperatures require a temperature derating.

| Screw thread: M5 | Screw torque value: 4Nm
2. The metal finger guard for frame sizes E, F and G are equipped with grommets, whilst figner guard H is equipped with stepped collars. Modify the stepped collars according to the cable isolated diameter, 5-10mm margin is recommended to feed the cable easier.
3. Note that if the cable lug is wider than the cross-section width/diameter of the finger guard (see Table 20),do not add cable lugs before feeding all cables though the finger guard. Crimp cable lug when the cables are fed through the finger guard.
4. Install shrinking tube for the uninsulated cable lug to fulfill the clearance and creepage requirement.
Note: In case the cables on the power terminals are installed without cable lug, it is recommended to follow the maintenance manual closely. Maintenance manual is available on
your request per Schaffner contact.

III.5
Use wired trap circuit or install external capacitive current control.
For configurations with TDJ option (refer to Tables 4, 5,
6), terminals D1- D1’, D2 - D2’and D3- D3’ are delivered with installed jumpers. When interconnected via an external capacitor contactor (not supplied by Schaffner, except in NEMA 3R type filters) they allow for load dependent disconnection of the trap circuit, if needed. Thus capacitive current can be minimized for low load operation. Estimation of required contactor size: see box to the right.
THE USE OF CAPACITIVE SWITCHES/CONTACTORs IS REQUIRED. OTHERWISE CAPACITOR LIFETIME MAY BE REDUCED.
III.6
Connect monitor switch TS- TS’
The monitor switch is a relay contact, which is open in ALARM state. It is constituted by a thermal switch NC 180°C (UL-approved) to detect overload of chokes. It may either be used to remotely disconnect the dr i ve’s load via respective input of drive control (check drive manual) or as alarm sensor for system control unit.
AN ENGAGED MONITOR SWITCH MUST LEAD TO IMMEDIATE LOAD SHUTDOWN AND INVESTIGATION OF THE PROBLEM.
III.7
Connect ecosine line side terminals L1, L2, L3
to power input protection (current limiting fuses – see below). IP 20 enclosure cable wiring please refer to the remarks for the load side cable wiring (III.4).
Note: For IP 20 filter versions the IP 20 finger guard must be installe d in order to achieve IP 20 protection. When the finger guard is not installed, Schaffner do not guarantee IP 20
protection.
Contactor performance estimate: Example: FN 3440-55-115 The nominal power rating in kW
multplies 20% and the grid voltage, then divided by the nominal voltage (400 V for FN 3440, 480 V for FN 3450 and FN 3452) is the approximate reactive power

Fuses
Ecosine evo passive harmonic filters need external over-current protection for compliance with UL/cUL standard. Fuses and associated fuse holders must be UL listed and rated for 100kA SCCR supplies. Table 22 and Table 23 show requested fuse current ratings for UL class J and, where UL compliance is not mandatory, for IEC class gG. The fuse rating is independent of the supply voltage.
A system with multiple ecosine evo
filters paralleled for a high power load need each a separate 3-phase line side fuse block, corresponding to the respective filter and according to above table. The drive’s application manual may prescribe line-side fuse protection as well, which in this case either corresponds to the sum of the filter fuse ratings or, if lower, would request separate drive fuses at its input.
An application, having one ecosine filtering harmonics of several drives, requires in any case line side fuse protection of the drives as well as the correct filter protection according to Table 22 and Table 23.

9. Filter maintenance
Ecosine evo passive harmonic filters described in this manual are equipped with long life components that ensure a satisfactory function for many years under normal operating conditions. Any operation under extreme conditions such as over-temperatures, overvoltage situations, polluted environments etc. reduces the life expectancy. Following maintenance recommendation will help maximizing filter lifetime.
Warnings:
High voltage potentials are involved in the operation of this product. Always remove line side power before attempting to perform maintenance, and let ample time elapse for the capacitors to discharge to safe levels (<42 V). Residual voltages are to be measured both line to line and line to earth.
Line side power must be disconnected prior to replacement of any part.

9.2 Fan
Schaffner ecosine evo p as s ive harmonic filters are reliable low maintenance products. Many products like power supplies, inverters or motor drives utilize fans for forced cooling to minimize size and weight. Ecosine filters are designed with a similar temperature management concept and therefore, fans may have to be maintained and replaced in certain intervals to sustain the function and value of the product. Fans are 100% field replaceable without the need to uninstall and disconnect the filter.
Forced cooling devices are needed for the operation of Schaffner ecosine evo passive harmonic filters up to their nominal rating. Such cooling devices must be checked and cleaned regularly (if installed) to ensure sufficient air flow at all times.
Note: increased audible noise is a typical indicator of a fan that needs maintenance or replacement also outside of a maintenance schedule.
Before cleaning or replacing the cooling devices, make sure to consult the recommended maintenance procedures and schedules of the supplier of the cooling device in use.
9.3 Power capacitors
The power capacitors supplied with the filter modules are high quality components with an expected life time of up to 100’000 hours (11 years). Nevertheless, their useful service life can be shortened by electrical or thermal stress beyond their specification.
Power capacitor damage may also be caused by severe abnormal supply voltage peaks (i.e. lightning – depending upon system protection), but may only be recognizable through the measurement of line side harmonics distortion. This may be checked with a modern energy meter or by regular checkup with a power quality analyzer. According to the above considerations, a 2 year inspection interval is advisable.
Note: an inspection should as well be performed after extreme overvoltage situations in the system. Note: Storage of capacitors Up to 3 years-long storage, electrolitic capac itors can be operat ed with out any restriction and the nominal
voltage can be applied without any prelim inary preparation. System reliability and life-time expectancy are not affected.
On the other side, a longer ( >3 yrs) storage of electrolitic capacitors without applying any voltage can weaken the dielectric properties because of disslution processes. The electrolitic solution is aggressive and it can affect and weaken the dielectric in the timeframe between production and product commissioning. The weak points are responsible for the higher leakage current shortly after the device turn-on on site.
The residual current of electrolitic capacitors depends upon time, voltage and temperature. The residual current increases after long storage without ap plying voltage.
The amplitude of resulting residual current during unit commissioning can be up to 10 times larger on short term. The capacitor’s residual current assumes the typical expected value at steady state for nominal voltage.
During comissioning after long storage, it is recommended to restore the dielectric characteristics by applying voltage progressively and with respect to the time frame the filters have been stored.
9.4 Electrical connections
Depending upon the environment and application, electrical connections, in particular threaded bolts and nuts, can degrade over time by means of losing their initial tightening torque. This holds true not only for the filter, but for any such joint within an electrical installation.
Therefore, Schaffner recommends to check and tighten all electrical connections on the occasion of a regular scheduled maintenance of the entire device that incorporates the filter.

Check of internal connections within the filters is not needed or should be conducted by a Schaffner service representative.

10 Trap circuit disconnect
The trap circuit disconnec t featur e is a modular option for the purpose of reducing the capacitive current during low load operation, if needed. With permanently connected trap circuit, cosφ vs. load shows following characteristics:
When the trap circuit is disconnected, cos(phi) returns to ~0.98. At the same time, the THID will increase. This may be negligible, since absolute values are low due to reduced load power. Needed external components (not part of ecosine filter) or system functions for fully automated capacitive current control:
| Motor load (power factor) monitoring device | Capacitor contactor
A reduced load system status may be available as system controller output signal. In this case, only adequate driving of capacitor contactor has to be assured.
Note: It is necessary to take into account overall concept of power factor correction. A system PFC correction unit with large capacitor banks may become obsolete or massively reduced, when harmonic filters are installed. In such cases it may not be necessary to install trap circuit disconnect functions.
Recommended settings:
Schaffner recommends to engage and disengage the trap circuit disconnect at following load levels:
Trap circuit status
Proposed load level
Disconnect
When load level drops under 10–15%
Connect
When load level rises above 20–25%

11. Troubleshooting Schaffner Ecosine harmonic filters are high quality products and have undergone rigorous testing and
qualification procedures. Every unit runs through suitable tests in our ISO 9001:2000 factories. Due to this reason no major issues need to be expected if the filter is installed, operated, and maintained as described in this document.
In the unlikely event of a problem, please contact your local Schaffner partner for assistance.
