installation documents<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Match the received full model and revision to the purchase order, current specification, terminal drawing and any applicable mounting instructions. The <a href=\"https:\/\/www.wehopower.com\/it\/product_category\/din-rail-power-supply\/dr-series-din-rail-power-supply\/\">WEHO DR-series category<\/a> provides the family context; the exact source photo and current DR-120 specification identify the example as DR-120-24, rated 24 V and 5 A.<\/p>\n<p>The documented envelope is <strong>65.5 mm width \u00d7 125.2 mm height \u00d7 100 mm depth<\/strong>. Width is along the rail, height is upright and depth extends from the front toward the rear mounting plane. Add the installation&#8217;s required ventilation, wiring-bend and maintenance access outside this envelope. Do not confuse a product dimension with a guaranteed cabinet clearance.<\/p>\n<p>The source label prints nominal input \u201c100-240VAC 3.3A\u201d and \u201c50\/60Hz\u201d; the current specification separately lists an operating range of 85\u2013264 VAC and 47\u201363 Hz. These are different document roles. Obtain confirmation for the ordered revision before accepting the site supply, rather than rewriting the physical label or automatically widening input acceptance.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Plan_isolation_input_protection_and_subsystem_boundaries\"><\/span>Plan isolation, input protection and subsystem boundaries<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Only a qualified person should perform installation and commissioning under the applicable site procedures and controlled manufacturer instructions. Identify every relevant energy source and possible backfeed, apply the required isolation controls and verification procedure, and manage any stored energy before mechanical or wiring work. This article is not a substitute for that procedure or a safe-to-touch determination.<\/p>\n<p>Plan protection for the input circuit and conductors even when the supply contains internal overload or short-circuit protection. Internal protection describes a component function; it does not by itself establish suitable upstream circuit protection, conductor protection or selective fault isolation. The responsible electrical designer must specify protective devices, ratings and coordination using the actual supply, circuit conditions and applicable requirements. This guide does not prescribe a universal fuse or breaker size.<\/p>\n<p>Define the DC subsystem separately from the machine&#8217;s main power. List controller, interface, sensor and other compatible 24 V demands, including simultaneous and startup states. Compare verified current and thermal conditions with the ordered model&#8217;s allowed operating limits. A 5 A nameplate does not establish available power for an unrelated motor or heating circuit.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Confirm_the_mounting_face_and_rail_engagement\"><\/span>Confirm the mounting face and rail engagement<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>On this source DR-120-24, the grey identity face, red WEHO mark and accessible terminals face the installer. The rear support is the mounting side. Reversing these faces can hide the identity, obstruct access and produce an unsupported arrangement. Do not attach the front face to the cabinet backplate simply because the metal case looks flat.<\/p>\n<p>Confirm the specified 35 mm rail, its profile and fixation against the ordered unit&#8217;s drawing and installation instructions. Inspect the rail and support before fitting the unit. The exact clip operation and any release tool depend on the construction: a generic \u201chook the top and snap the bottom\u201d description is not reliable evidence for every revision. Do not pry an unidentified latch or add an improvised front bracket.<\/p>\n<p>After fitting, verify positive rear engagement and stability using the prescribed inspection method, without assuming that a unit resting against a rail is securely mounted. Confirm orientation, access and any specified spacing with neighbouring components. The fanless metal enclosure still needs its documented thermal conditions; ventilation openings are not cable-entry points.<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls.png\" alt=\"How to Install a DIN Rail Power Supply: Orientation, Protection and Acceptance Checks  title=\" class=\"wp-image-18517\" how to install din rail power supply: protection and acceptance checks title =\"\" srcset=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls.png 1536w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls-300x200.png 300w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls-1024x683.png 1024w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls-768x512.png 768w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-water-treatment-controls-18x12.png 18w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n<p>The first application illustration places the component in a protected dry workroom for water-treatment auxiliary controls. Tanks and piping establish the industrial context, but they do not prove environmental protection or pump compatibility. Verify the actual cabinet&#8217;s moisture, contamination and temperature conditions before selection. The pictured supply remains unwired and is not shown powering the pumps.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Use_the_exact_terminal_drawing_for_connection_planning\"><\/span>Use the exact terminal drawing for connection planning<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The photographed DR-120-24 has four upper DC terminals, physically left to right <strong>+V, +V, \u2212V, \u2212V<\/strong>. Its three lower input terminals are protective earth, N and L. This is not the blue-front NDR model&#8217;s output order; similar names do not make the terminal layouts interchangeable.<\/p>\n<p>Plan conductors, protective-earth connections, termination preparation, routing and tightening from the controlled instructions for the ordered revision. Keep input and output identification unambiguous. Do not invent conductor size or torque from the appearance of a terminal, and do not use a generated image as a wiring diagram. Repeated output terminals do not establish separate 5 A outputs; assess the connected total and permitted terminal use.<\/p>\n<p>The source front has a small DC OK window at the upper right, but no front +V ADJ opening or legend. Do not transfer an adjustment procedure from another supply onto this one. If adjustment is required, obtain the correct ordered-unit documentation and access instructions rather than searching for or creating an imagined front control.<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel.png\" alt=\"How to Install a DIN Rail Power Supply: Orientation, Protection and Acceptance Checks  title=\" class=\"wp-image-18518\" how to install din rail power supply: protection and acceptance checks title =\"\" srcset=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel.png 1536w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel-300x200.png 300w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel-1024x683.png 1024w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel-768x512.png 768w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-commercial-kitchen-panel-18x12.png 18w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n<p>The second scene shows a modular commercial-kitchen equipment assembly bay, with an isolated control-panel fitting fixture beside stainless equipment casings.

The record should identify the exact unit and revision, rear rail engagement, orientation, terminal mapping, protective-earth arrangement, input protection, conductor terminations and unresolved questions. Use authorised procedures and suitable instruments; the installer determines what checks are safe and applicable at each stage.<\/p>\n<p>Evaluate output at the actual connected control loads, including the demanding simultaneous state and any startup behaviour that matters to those devices.
