6 6 ECOsine active Harmonic Filters Maintenance Manual for FN 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. High-frequency interferences In a residential environment, high-frequency interferences could occur, which necessitate interference suppression. WARNING Note Please note that there are additional manuals for some product variants. For the latest versions of these manuals go to It particularly applies to types FN / GL, please observe the special EMC-Filter Manual for these types (ECOsine EMC Filters for Applications with GL)

7 ECOsine active Harmonic Filters Maintenance Manual for FN 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.

8 8 ECOsine active Harmonic Filters Maintenance Manual for FN 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 IEC 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 Products 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. FN3420 series, 3-wire filters, models A FN3430 series, 4-wire filters, models A Overvoltage class (EN50178) ECOsine active are designed according to EN overvoltage class III

10 10 ECOsine active Harmonic Filters Maintenance Manual for FN Introduction

11 ECOsine active Harmonic Filters Maintenance Manual for FN 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. Mains supply Compensating current Neutral 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.
