APPENDIX B
Use of TB Wood’s WLF Series Line Filters
SECTION 1
INTRODUCTION
This Appendix documents the specifications for TB Wood’s WLF Series line filters. The Appendix also
contains installation and usage information relative to these products.
Proper installation of these filters with the correct model of E-trAC ® WFC HT Series inverter or XFC Series
micro-inverter will aid in complying with CE (Conformite Europeen) EMC directives. These filters will limit
emissions, per EMC Directive 89/336 EEC, to meet the following specifications:
EMA (Electromagnetic emission)
EN 50081-1 Basic specification, “Emitted Interference”
EN 55011 Emitted Interference - Industrial, Scientific and Medical Installations
EN 55014 Emitted Interference - Residential Installations
EMB (Electromagnetic interference)
EN 50082-2 Basic specification, “Interference Immunity”
EN 50140 Electromagnetic Fields
EN 60801 Static Discharge
ENV 50142 Surge
IEC 801-4 Burst on mains lead/data line
To assure compliance with the EMC directive, the following procedures must be observed:
• Installation of a line filter with properly matched WFC HT inverter.
• To meet the B Emission Curve for EMC (Commercial) Compliance, an output reactor may also be
required. No output filter or reactor is required to meet the A Emission Curve for EMC (Industrial)
Compliance (reduces leakage current to a level below 3.5 mA).
• Installing shielded motor cable and correctly grounding the shield.
• Observe general RFI suppression measures (refer to Section 5 – Interference suppression
measures/EMC [Electromagnetic Compatibility] ).
Note that the WLF series of line filters does not bear the CE mark. Although the filters have been tested with
the inverters for compliance, installation practices and other wiring concerns make CE compliance with EMC
directives the responsibility of the installer of the equipment.
In addition, motor output wiring considerations required to meet the CE directives are also presented.
Similarly, the WLF series of line filters is not UL listed or recognized. If local codes permit, the filters may be
used in the United States as a solution for EMI and RFI problems either caused by or effecting the operation
of an E-trAC
®
series inverter.
