NOTE 1 Requirements for the installation of earth-leakage and open-circuit protective devices are given in EN 50107-1. NOTE 2 Requirements for earth-leakage and open-circuit protective devices used with inverters and converters are specified in EN 61347-2-10. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE Where the terms “voltage” and '“current” are used, they refer to r.m.s. values unless otherwise stated. 3.1 type A device earth-leakage or open-circuit protective device generally designed to be built into the enclosure of a transformer and not intended to be mounted outside a transformer without special precautions NOTE A type A device normally protects only the transformer in which it is mounted. 3.2 type B device earth-leakage or open-circuit protective device consisting of one or more separate elements so designed that it can be mounted outside a transformer and housed in an enclosure that provides all necessary protection according to its markings NOTE 1 The enclosure may consist of the sign in which the device is mounted; the sign having a protection according to its markings. NOTE 2 The device may protect more than one transformer.

Such means might include, e.g. measuring the current reflected into the primary winding of the transformer or measuring a change in circuit power factor. 3.7 sensor device that detects an earth-leakage current or, in the case of an open-circuit protective device, detects when the secondary load current has fallen below the shut-down current limit, and either causes a protective switch to operate or otherwise causes the output voltage of a transformer to be removed 3.8 protective switch part of an earth-leakage or open-circuit protective device that disconnects the mains supply from a transformer 3.9 response time time from the start of the fault condition until the protective device removes the output voltage 3.10 secondary load current current flowing in the output circuit of transformer supplying one or more tubes 4 General requirements EN 61347-1:2001, Clause 4, shall apply, with the words “earth-leakage protective device” or “open- circuit protective device” (as appropriate) substituted for “lamp controlgear”. 5 Tests 5.1 With the exception of EN 61347-1:2001, Subclause 5.4 (see 5.2), EN 61347-1:2001, Clause 5, shall apply, with the words “earth-leakage protective device” or “open-circuit protective device” (as appropriate) substituted for “lamp controlgear”.

The results shall be assessed as follows: 1) if all three samples pass all the tests, the batch shall be deemed to conform to this European Standard; 2) if two or more samples fail any of the tests, the batch shall be deemed not to conform to this European Standard; 3) if one sample fails any of the tests, the tests shall be repeated on a second batch of three devices; 4) if all three devices from this second batch pass all the tests, the batch shall be deemed to conform to this European Standard; 5) if any device from this second batch fails any of the tests, the entire batch shall be deemed not to conform to this European Standard. 6 Classification EN 61347-1:2001, Clause 6 shall apply, with the words “earth-leakage protective device” or “open- circuit protective device” (as appropriate) substituted for “lamp controlgear”. 7 Marking 7.1 Items of marking The following items shall be marked, either: a) on the device itself, in the case of type A or type B devices; or b) on the label attached to the transformer in which the device is housed, and in the case of type C devices with: 1) the number of this European Standard, i.e. EN 50107-2; 2) the items specified in EN 61347-1:2001, Subclause 7.1 a), b), f), and l), with the words “earth-leakage protective device” or “open-circuit protective device” (as appropriate) substituted for “lamp controlgear”. 7.2 Durability of marking The durability of the marking shall conform to the requirements of EN 61347-1:2001, Subclause 7.2. 7.3 Additional information In addition to the items specified in 7.1, the following information, if applicable, shall be given in the manufacturers instructions to be provided with both earth-leakage and open-circuit protective devices: a) the items specified in EN 61347-1:2001, Subclause 7.1 h), i) and k), with the words “earth- leakage protective device” or “open-circuit protective device” (as appropriate) substituted for “lamp controlgear”; Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 06 07:48:26 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 50107-2:2005 - 8 - b) the information necessary for the test specified in EN 50107-1:2002, Clause 18, to be carried out; c) the information necessary for the safe installation of the device in accordance with the requirements of EN 50107-1; d) the information necessary for the device to be disabled manually for maint
