In this guide, I will explain the ESTUN E315P Terminal Wiring procedure step by step, including wire preparation, terminal connection, connector installation, and important checks that should be completed before powering on the controller.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Understanding ESTUN E315P Terminal Wiring<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Correct <a href=\"https:\/\/www.youtube.com\/watch?v=GwlCHLs7I6U&amp;t=16s\" data-type=\"link\" data-id=\"https:\/\/www.youtube.com\/watch?v=GwlCHLs7I6U&amp;t=16s\" target=\"_blank\" rel=\"noopener\">ESTUN E315P<\/a> Terminal Wiring is essential for establishing stable electrical connections between the controller and the press brake electrical system. During installation, each conductor must be properly prepared, inserted into the correct terminal, and securely clamped before the connector is installed into the corresponding PCB slot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The E315P uses spring-loaded terminal connectors. Instead of simply inserting a wire into the connector, the operator must open the terminal clamp, prepare the conductor to the recommended length, insert it correctly, and then release the clamp to secure the connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before starting, identify the correct connector according to the controller documentation and machine electrical schematic. It is also recommended to identify the connector orientation in advance because the completed connector must later be installed into the PCB slot in the correct direction.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Connect ESTUN E315P Terminal Wiring<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The terminal wiring procedure should be completed systematically. Working one conductor at a time makes it easier to verify each connection and reduces the possibility of incorrect terminal assignments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Locate the Correct Terminal<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First, identify the terminal that corresponds to the required signal according to the electrical schematic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use a suitable tool to press and hold the <strong>spring-loaded release button<\/strong> on the terminal connector. Pressing this button opens the internal clamping mechanism and prepares the terminal for wire insertion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not insert the conductor by force without opening the terminal clamp, as this may damage the wire or prevent a secure electrical connection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Strip the Wire Insulation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Prepare the conductor by removing approximately <strong>6.4 mm (1\/4 inch)<\/strong> of insulation from the end of the wire.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The stripped section should expose enough conductor to create reliable electrical contact inside the terminal without leaving excessive bare copper outside the connector.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Take care not to damage or cut the conductor strands during stripping. Damaged strands can reduce the effective conductor cross-section and weaken the mechanical connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Image summary:<\/strong> Strip approximately 6.4 mm of insulation from the conductor before connecting it to the terminal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Insert the Bare Conductor<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While continuing to hold the spring-loaded release button, insert the stripped conductor into the terminal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the connection procedure, the wire should be inserted at approximately <strong>90 \u062f\u0631\u062c\u0629<\/strong> and pushed sufficiently deep into the terminal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Make sure the exposed metal conductor, rather than the insulation, enters the electrical contact area.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"487\" height=\"158\" src=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4.png\" alt=\"ESTUN E315P Terminal Wiring\" class=\"wp-image-88119\" srcset=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4.png 487w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4-400x130.png 400w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4-18x6.png 18w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4-360x117.png 360w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4-430x140.png 430w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-4-150x49.png 150w\" sizes=\"(max-width: 487px) 100vw, 487px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The conductor should remain straight and should not contain loose strands extending outside the terminal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Release the Terminal Button<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once the conductor has been fully inserted, release the spring-loaded button.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The internal metal teeth should now clamp the bare conductor securely and establish the electrical connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After releasing the button, gently pull the wire to verify that it is properly secured. The conductor should remain firmly inside the terminal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the wire moves easily or comes out, reconnect it before continuing with the remaining terminals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Image summary:<\/strong> Release the spring-loaded button after insertion so the internal terminal clamp can securely hold the conductor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Check the Terminal Connection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After connecting each wire, inspect the terminal carefully.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A correct ESTUN E315P Terminal Wiring connection should meet the following conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The conductor is inserted completely.<\/li>\n\n\n\n<li>The terminal clamps the bare metal conductor.<\/li>\n\n\n\n<li>The wire insulation is not trapped inside the electrical contact area.<\/li>\n\n\n\n<li>Excessive bare copper is not exposed.<\/li>\n\n\n\n<li>No loose conductor strands are visible.<\/li>\n\n\n\n<li>The wire remains secure during a gentle pull test.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Performing this simple inspection after every connection can prevent difficult-to-diagnose electrical problems later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Complete the Remaining Connections<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Repeat the same procedure for all required conductors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Follow the electrical schematic systematically rather than relying only on wire colors or connector positions. Similar wires installed next to each other can easily be confused during assembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After completing several terminals, it is useful to compare the connections with the electrical schematic again before proceeding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This reduces the risk of discovering multiple incorrect connections only after all wiring has been completed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 7: Inspect the Complete Connector<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once all conductors have been connected, perform a final inspection before installing the connector into the controller.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Terminal numbers<\/li>\n\n\n\n<li>Signal assignments<\/li>\n\n\n\n<li>Wire positions<\/li>\n\n\n\n<li>Connector orientation<\/li>\n\n\n\n<li>Stripping lengths<\/li>\n\n\n\n<li>Clamping condition<\/li>\n\n\n\n<li>Loose conductors<\/li>\n\n\n\n<li>Exposed copper<\/li>\n\n\n\n<li>Possible short circuits<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The connector should only be installed after all connections have been confirmed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 8: Install the Connector Into the PCB Slot<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After completing the inspection, insert the terminal connector into the corresponding PCB slot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The connector is <strong>orientation-sensitive<\/strong>, so verify its direction before installation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not rotate, reverse, or force the connector into the slot. If it does not fit correctly, remove it and check the connector position and orientation again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once installed, confirm that the connector is fully seated and cannot become loose during normal machine operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Image summary:<\/strong> Insert the completed terminal connector into the correct PCB slot only after verifying its wiring and orientation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Important Checks Before Powering On<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Completing the physical connection does not mean the ESTUN E315P Terminal Wiring process is finished. A final electrical inspection should always be performed before applying power to the controller.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Verify Pin Assignments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Compare every conductor with the electrical schematic and controller terminal definition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pay particular attention to power, ground, input, and output connections. Incorrectly connecting these circuits may result in abnormal operation or electrical damage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Check for Short Circuits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Inspect neighboring terminals for loose wire strands or excessive exposed copper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A small conductor strand touching an adjacent terminal can create a short circuit that may be difficult to identify visually after the connector has been installed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Check Connector Orientation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm that each connector has been inserted into the correct PCB position and in the correct orientation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Connector appearance alone should not be used to determine its location. Always refer to the interface definition and electrical schematic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Confirm Secure Connections<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Perform a final mechanical inspection of the wiring.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conductors should not become loose when moved gently, and connectors should remain firmly seated in their corresponding slots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Only after these checks have been completed should power be applied to the controller.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"533\" height=\"800\" src=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-533x800.png\" alt=\"\" class=\"wp-image-88124\" srcset=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-533x800.png 533w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-200x300.png 200w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-768x1152.png 768w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-8x12.png 8w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-341x512.png 341w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-430x645.png 430w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-700x1050.png 700w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5-150x225.png 150w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/08\/image-5.png 1024w\" sizes=\"(max-width: 533px) 100vw, 533px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Common ESTUN E315P Terminal Wiring Mistakes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding common wiring mistakes can help technicians avoid unnecessary commissioning problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Clamping the Wire Insulation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One common mistake is inserting the wire insufficiently so that the terminal clamps the insulation instead of the conductor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This may create an unstable or completely open electrical connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always confirm that the terminal clamp makes direct contact with the bare conductor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using an Incorrect Stripping Length<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If too little insulation is removed, the conductor may not reach the terminal contact correctly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If too much insulation is removed, excessive bare copper may remain exposed and increase the risk of a short circuit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use the recommended stripping length of approximately <strong>6.4 mm<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Leaving Loose Wire Strands<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Stranded conductors should remain together when inserted into the terminal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Loose strands can reduce connection quality or accidentally contact neighboring terminals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Inspect the conductor before insertion and make sure all strands enter the terminal correctly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reversing the Connector<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Terminal connectors must be installed in the correct orientation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Installing a connector incorrectly may result in signals being connected to the wrong terminals.
