Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz Part 4-7: Portable low voltage decoupling filters - Safety requirements

This product safety standard applies to the filter part of portable devices for household and similar uses consisting of the filter part, a plug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and a socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c.. This standard does not cover phase couplers. Filters including batteries are not covered by this standard.

133 Introduction
134 When certifying or making declaration of conformity to the Low Voltage Directive 2014/35/EU in order to
135 CE mark the device it is important to state that the CE marking is only valid for the filter parts of the
136 product. The plug parts and socket-outlets parts are not covered by the Low Voltage Directive and are
137 therefore expected to comply with the relevant national standards.

138 1 Scope
139 This document applies to the filter part of portable devices for household and similar uses (hereafter
140 referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a
141 provision for connection by terminals or with a non-rewirable cord and a socket-outlet or an appliance
142 outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for
143 nominal voltages not exceeding 250 V a.c.
144 The filtering functions are described in EN 50065-4-1.
145 This document does not cover phase couplers.
146 Portable decoupling filters are not used as part of the fixed installation, where EN 50065-4-2 applies.
147 Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter
148 part are expected to comply with the relevant national standard(s).
149 Appliance inlets and appliance outlets connected to the filter part are expected to comply with the relevant
150 parts of the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not
151 covered by this document.
152 This document can be used for portable mains communication devices when no other product standard
153 exists.
154 This document can be used for other portable mains filters other than those described in EN 50065-4-1
155 when no other product standard exists.
156 Filters including batteries are not covered by this document.
