Before servicing: contact ETS-Lindgren – servicing (or modifying) the unit by yourself may void your warranty. If you attempt to service the unit by yourself, disconnect all electrical power before starting. -
Page 9: Introduction
INTRODUCTION ETS-Lindgren Filter Panels are electromagnetically isolated Electromagnetic Interference (EMI) Filter cabinets with EMI isolated filter elements. Filters designated as -TS are equipped with transient protection devices (MOVs). The filter is designed to filter internally and externally generated EMI conducted emissions and arrest high transient currents when equipped with MOVs. -
Page 10: Filter Components
MOVs in the panel. There are NO USER SERVICEABLE PARTS inside the filter elements. Should a filter element be determined to be defective, contact ETS-Lindgren to order a replacement or to schedule its return or replacement. -
Page 11: Automatic Discharge
Some signal filters contain bleeder resistors that will automatically reduce the voltage on any component to less than 50 V within five (5) seconds after the removal of input power. Contact ETS-Lindgren for details. Always discharge filters as described in the SHORTING STICK section of this manual. -
Page 12: Short Circuit Current Rating
Once the power correction coil is installed, the operating power frequency range of the filter then becomes 350 Hz to 450 Hz. For operation at other frequencies or DC, the coils must be disconnected. Please call ETS-Lindgren before proceeding. Current As specified on filter label. -

10% to 15% of the rated current of the filter. The presence of this current does not indicate a problem unless it is above the level expected. Contact ETS-Lindgren for specific leakage current for each particular filter model. -
Page 15: Inspection And Cleaning Of Wiring Compartments
User’s own procedures for the removal of spills, dirt, debris and corrosion should suffice. Should EMI gasket become torn or unusable, contact ETS-Lindgren to order replacement part E-903-008. The MOV arrestor (if provided) should be replaced when an MOV test (see Capacitance Measurement and MOV Inspection Procedure section) fails to indicate a working MOV. -
