I&#8217;m a supplier of Altivar Series Low Voltage VFDs (Variable Frequency Drives), and I often get asked about installing the cooling fan for these drives. It&#8217;s an important part of keeping your VFD running smoothly, so I thought I&#8217;d share some tips on how to do it right. <a href=\"https:\/\/www.plcsupplychain.com\/schneider\/altivar-series-low-voltage-vfds\/\">Altivar Series Low Voltage VFDs<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.plcsupplychain.com\/uploads\/47749\/small\/b-r-x20bc0043-10-canopen-bus-controller0988b.jpg\"><\/p>\n<h3>Why You Need a Cooling Fan<\/h3>\n<p>First off, let&#8217;s talk about why the cooling fan is so crucial. Altivar VFDs generate heat during operation. If this heat isn&#8217;t dissipated properly, it can cause the internal components to overheat. Overheating leads to reduced performance, shortened lifespan, and even potential breakdowns of the drive. The cooling fan plays a vital role in moving air through the VFD, carrying away the excess heat and maintaining a stable operating temperature.<\/p>\n<h3>What You&#8217;ll Need<\/h3>\n<p>Before you start the installation process, gather the following tools and materials:<\/p>\n<ul>\n<li>The appropriate cooling fan for your Altivar VFD model. Make sure to double &#8211; check the compatibility. You can find this info in the product manual or reach out to us if you&#8217;re not sure.<\/li>\n<li>A Phillips &#8211; head screwdriver. Most of the screws on the VFD and the fan mounting brackets are Phillips &#8211; head.<\/li>\n<li>Safety gloves and goggles. Safety first, right? Working with electrical equipment can be dangerous, so these will protect your hands and eyes.<\/li>\n<li>A clean, dry cloth. This will come in handy for cleaning the area around the fan installation point.<\/li>\n<\/ul>\n<h3>Step 1: Power Down and Disconnect<\/h3>\n<p>This is a no &#8211; brainer, but it&#8217;s also the most important step. Before you do anything, turn off the power supply to the Altivar VFD. You don&#8217;t want to risk an electrical shock or damage to the drive. Then, unplug it from the power source. If there are any other connected cables, like control cables or load cables, carefully disconnect them as well. Label each cable if you need to, so you can easily reconnect them later.<\/p>\n<h3>Step 2: Locate the Fan Installation Area<\/h3>\n<p>Open up the VFD enclosure. You&#8217;ll typically find a designated area for the cooling fan. It might be on the side, top, or back of the drive, depending on the model. The area will usually have mounting holes that match the holes on the cooling fan. Some VFDs may also have markings or labels indicating where the fan should go.<\/p>\n<h3>Step 3: Clean the Area<\/h3>\n<p>Take your clean, dry cloth and gently wipe the surface where the fan will be installed. Remove any dust, debris, or dirt. A clean surface ensures a good seal between the fan and the VFD, which helps with the airflow and prevents dust from getting inside the drive.<\/p>\n<h3>Step 4: Mount the Cooling Fan<\/h3>\n<p>Place the cooling fan over the mounting holes in the VFD. Make sure it sits flush and that all the holes align properly. Then, insert the screws into the holes. Start by hand &#8211; tightening them to make sure the fan is properly positioned. Once it&#8217;s in place, use your Phillips &#8211; head screwdriver to fully tighten the screws. But don&#8217;t over &#8211; tighten them, as this could damage the fan or the VFD.<\/p>\n<h3>Step 5: Connect the Fan Wires<\/h3>\n<p>The cooling fan will have wires that need to be connected to the VFD. Usually, there will be a connector on the VFD specifically for the fan. Match the wires from the fan to the corresponding pins on the connector. Make sure the connection is secure. If the wires aren&#8217;t already color &#8211; coded, refer to the fan&#8217;s wiring diagram to ensure you&#8217;re connecting them correctly.<\/p>\n<h3>Step 6: Reassemble the VFD<\/h3>\n<p>Once the fan is mounted and wired, carefully close the VFD enclosure. Replace any screws or fasteners that you removed earlier. Make sure the enclosure is sealed properly to prevent dust and moisture from getting inside.<\/p>\n<h3>Step 7: Reconnect the Cables and Power On<\/h3>\n<p>Reconnect all the cables that you disconnected earlier, following your labels if you used them. Then, plug the VFD back into the power source. Turn on the power supply and check if the cooling fan is running. You should be able to hear the fan spinning and feel the air being moved. If the fan doesn&#8217;t start, double &#8211; check your wiring and connections.<\/p>\n<h3>Troubleshooting Tips<\/h3>\n<ul>\n<li>If the fan is making a loud or unusual noise, it could be misaligned. Turn off the power and check if the fan is properly mounted and not hitting anything inside the enclosure.<\/li>\n<li>If the fan isn&#8217;t running at all, check the wiring connections. Make sure the wires are securely connected and that there are no loose or damaged wires.<\/li>\n<li>If the VFD still overheats even after installing the new fan, there could be other issues.
