1.1 Intended use
The ECOsine® active harmonic filter is used for active compensation of reactive power and
harmonic content and for load balancing.
Please ensure that no compensation systems, which are not detuned, are connected to the
same grid. Otherwise interactions between ECOsine® active and these compensation
systems may occur.
DANGER
Dangerous voltage
Risk of death due to short circuits and electric shock if the
active filter is opened improperly. The discharge time of
the intermediate circuit after disconnecting from the
mains can be more than 5 minutes.
All interventions involving opening the device cover or
removing or installing the connection cable may only be
performed by qualified personnel.
WARNING
High-frequency interferences
In a residential environment, high-frequency interferences
could occur, which necessitate interference suppression.
Note
Please note that there are additional manuals for some product variants. For the latest
versions of these manuals go to www.schaffner.com
It particularly applies to types FN3420-100/120-400-3-GL, please observe the special
EMC-Filter Manual for these types (ECOsine EMC Filters for Applications with GL)

1.2 Personnel qualification
Installation of the ECOsine® active filter, inspections for proper operation, and certain
troubleshooting measures may only be performed by qualified personnel. All other
measures may be performed by people who have read these instructions.

1.3 Environmental conditions / Exclusion
of warranty
This document classifies groups of environmental parameters and their severities to which
ECOsine® active harmonic filters are subjected when mounted for stationary use at weather
protected locations under use conditions, including periods of erection work, down time,
maintenance and repair. The lifetime of electronic equipment is depending on the
environmental conditions they are exposed to. Especially in harsh environments lifetime is
reduced due to the corrosiveness of the atmospheric environment. Generally corrosion in
micro or power electronics depends on several variants such as the package type, materials
involved, assembly processes, moisture, inorganic and organic contaminants, atmospheric
pollutants, temperature, thermal stress and electrical bias. To increase the lifetime
Schaffner provides all ECOsine® active filters with the ability to work within pollution degree
2 (PD2) and does use coated PCB’s according to IEC61721-3-3. Schaffner standard PCB
construction complies with class 3C2. Please carefully read the provided information and
check if your application fulfills the required specifications as Schaffner expressly points
out that the manufacturer's warranty shall lapse with immediate effect if ECOsine®
active harmonic filters are transported, stored, installed or operated outside their
published specifications.
Important
ECOsine® active harmonic filters (AHF) listed below are IP20 or IP54
devices to be installed in an environment in compliance with the
requirements named in this document.
All AHF must be installed in a clean, dry location, e.g. in sufficiently
ventilated or air conditioned electric cabinets or closed electric rooms.
Contaminants such as oils, liquids, corrosive vapors, abrasive debris,
dust and aggressive gases must be kept out of the filter enclosure.
WARNING: Conductive dust may cause damage to ECOsine®
active harmonic filters. Ensure that installation site of ECOsine®
active is free of conductive dust.

The values given in cm3/m3 have been calculated from the values given in mg/m3
and refer to a temperature of 20 °C and a pressure of 101,3 kPa. The table uses
rounded values.

Mean values are expected long-term values. Maximum values are limit or peak
values, occurring over a period of time of not more than 30 min per day.

IEC 60721-3-3 is only applied to the coated PCB covered areas and not the entire device.
The unprotected areas, such as connections, terminations and exposed magnetics, may not
survive these exposure levels over time.

2.1 Principle of operation
The ac mains current, which is drawn by a non-linear load, is measured by ECOsine® active
either directly or indirectly via external current transformers. The harmonic content and
reactive power components are detected and processed in a digital control structure. The
active filter continually generates a compensating current that offsets the harmonic content
and reactive current in the load, so the ac mains only has to provide the minimum
fundamental in phase current.
Compensating current

Load

Fig. 1: Principle of operation of the ECOsine® active filter
The active filter instantly adapts to all changes in the load and the systems harmonic
content spectrum, in order to be able to optimally respond at any time.
