EMC Line Filters for Chassis Mounting
General Mounting and Installation Guidelines

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.
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 (<42V). Residual voltages are to be measured both line to line and
line to earth.
EMC filters may cause leakage currents to ground. Always connect the filter to protective
earth (PE) first, then continue with the wiring of phase/neutral terminals. When
decommissioning the filter, remove the PE connection at the end.
Follow the general installation notes closely. Ensure that cooling slots (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.
EMC filters are lossy electrical components. Filter surfaces and terminals may get hot under
full load operating conditions.
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
