OEM lighting order, \u201cEN 61347\u201d should start a document review, not end one. Ask which exact controlgear model, construction revision and standard edition a report covers, then check the conditions under which that component may be incorporated into the finished luminaire. A logo on a housing, an attractive sample or a product-family description is not a substitute for that evidence.<\/p>\n<p>The WL-100-12 is a useful example of why identification matters. Its photographed label states DC 12 V, 8.3 A output and 100\u2013265 VAC, 0.8 A input. The available source package does not establish a matching EN 61347 report for that sample. This article therefore explains the purchasing checks; it does not present the photographed unit as certified to the standard.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Specify_the_applicable_document_set\"><\/span>Specify the applicable document set<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The publisher describes <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/64713\" target=\"_blank\" rel=\"noopener\">IEC 61347-2-13:2024<\/a> as the particular safety requirements for electronic controlgear for LED light sources.

These publisher summaries identify scope and editions; they do not provide a full compliance assessment of any WEHO product.<\/p>\n<p>Ask the project\u2019s responsible engineer or assessment body which edition and conformity route apply to the destination and finished product. Do not assume that the newest catalogue entry is automatically the required edition for every order. Safety documentation also does not establish dimming quality, flicker, lifetime or other performance requirements unless those are separately supported.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Connect_the_paperwork_to_the_delivered_unit\"><\/span>Connect the paperwork to the delivered unit<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table>\n<thead>\n<tr>\n<th>Purchasing check<\/th>\n<th>Evidence to request<\/th>\n<th>What would block acceptance<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Exact identity<\/td>\n<td>Full model, ratings, label artwork and construction revision<\/td>\n<td>A similar family name with a different output or enclosure<\/td>\n<\/tr>\n<tr>\n<td>Report coverage<\/td>\n<td>Report number, issuer, tested models, editions and relevant conditions<\/td>\n<td>A certificate image without a way to establish its scope<\/td>\n<\/tr>\n<tr>\n<td>Installation conditions<\/td>\n<td>Required enclosure, earthing, terminals, thermal limits and mounting instructions<\/td>\n<td>Conditions that the intended luminaire cannot meet<\/td>\n<\/tr>\n<tr>\n<td>Series production<\/td>\n<td>Agreed approved sample and change-notification process<\/td>\n<td>Unannounced changes to materials, protection or identification<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>A buyer need not reproduce laboratory work to make this check useful.

The matching drawing gives a 138 \u00d7 50 mm footprint and two diagonally opposed factory fixing slots. This is chassis mounting, not a DIN-rail product. Installation drawings should preserve access to the terminal guards and ventilation rather than treating the small footprint as the complete space requirement.<\/p>\n<p>There are material document differences to resolve before releasing a batch. The archived drawing\/header and dimension table disagree on height, at 23 and 24 mm. The current product page also lists different electrical figures from the photographed 8.3 A sample. Do not average these values or silently substitute one source for the other.
