Sine Wave Filter Series FN 5040, FN 5045 and FN 5040 HV
Mounting and Installation Guidelines
Please read and follow the safety, application and installation notes.
Important safety notes
Filter installation, start-up, operation and maintenance (if any) has to be carried out by a
trained and certified electrician or technician, who is familiar with safety procedures in
electrical systems.
Danger of electrical shock! High voltage potentials are involved in the operation of this
product. Always remove power before handling energized parts of the filter, 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.
Always connect the filter to protective earth (PE) first, then continue with the wiring of phase
terminals. When decommissioning the filter, remove the PE connection at the end. The sine
wave filter must not be operating without connected motor.
Follow the general installation notes closely. Ensure that cooling slots, openings or grids (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.
For safety reasons, LC sine wave filters must be installed in a way to prevent access of non-
qualified persons to the filters.
Sine wave filters are lossy electrical components. Filter surfaces and terminals may get hot
under full load operating conditions and can exceed surface temperature >80 °C.
Always practice the safety procedures defined by your company and by applicable national
electric codes when handling, installing, operating or maintaining electrical equipment.
In case of uncertainty and questions please contact your local Schaffner partner for
assistance.

- Page 2 Special attention should be paid to cable dimensioning, fuses, grounding, shutdown, disconnection, and overcurrent protection. In order to get the maximum benefit out of the Schaffner filters, please also consult “Basics in EMC and Power Quality”, published in the download section of www.schaffner.com. These additional guidelines provide helpful hints for HF-grounding, shielding, proper cable routing, etc.

- Page 4 In many applications a shielded motor cable may not be required when a sine wave filter is applied with a motor drive. Anyhow, due to other possible influences of common mode disturbances Schaffner does recommend to use shielded motor cables. This is to avoid back-coupling of radiated interferences to the mains cable at the frequency range from 1–30 MHz.
