Important user notice

 

Schaffner Ecosine

® 

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 

applications.  

  

 

 

Ecosine

® 

filters with protection category IP20/NEMA1 must be mounted in a clean, dry location. 

Contaminants such as oils, corrosive vapors and abrasive debris must be kept out of the enclosure. 
These filter enclosures are intended for indoor use, primarily to provide a degree of protection against 
contact with enclosed equipment. These enclosures offer no protection against airborne contaminants.   

 

 
 

Important safety considerations

 

 

 

Note: 

Filter installation has to be carried out by a trained and certified electrician or technician, who is 

familiar with installation and safety procedures in three-phase power systems.  

Warning: 

High voltage potentials are involved in the operation of Ecosine

® 

filters. Always remove power 

before handling energized parts of the filter and let ample time elapse (> 1 minute) for the capacitors to 
discharge to safe levels.  

Warning: 

Follow the installation instructions closely. Ensure that fans and cooling slots are free from 

obstructions that could inhibit efficient air circulation. Do not operate the filter in ambient conditions 
outside of specifications.  

Note: 

Do not operate Ecosine

® 

filters on unsymmetrical loads, on linear loads, or with single-phase 

equipment.   

Note: 

Always use an upstream disconnect or protection device as required by most national and 

international electric codes.  

Note: 

Always connect the filter to protective earth (PE) first, then continue with the wiring of the trap- 

disconnect (if needed) and phase connectors.  

Note: 

Follow the Schaffner instructions closely when doing maintenance work. Use exclusively spare 

parts recommended and approved by Schaffner.  

Note: 

Always practice the safety instructions defined by your company when handling, installing, 

operating, or maintaining Ecosine

® 

harmonic filters.  

Note: 

In case of uncertainty and questions please contact your local Schaffner partner for assistance.
