When using the inverter in an environment with high operating temperature, additional cooling measures must be taken to ensure that the ambient temperature is stable within the range required by the inverter user manual (-10~+40\/45\u2103).In the electric control box, the frequency converter should generally be installed on the upper part of the box, and it is strictly prohibited to install the heating element close to the bottom of the frequency inverter! In addition, the cooling fan of the inverter should be inspected and cleaned regularly during use.<\/li><li>Humidity factor<br \/>When the ambient humidity is greater than 90%, the insulation of the components inside the inverter will deteriorate, causing the inverter to malfunction. Therefore, putting desiccant in the frequency converter becomes a necessary means of moisture removal when necessary.<\/li><li>Corrosive gas<br \/>Since corrosive gases have a great destructive effect on the electrical insulation performance of the internal PCB board and plastic product casing of the inverter, a sealed casing that meets the safety regulations should be used when using the inverter in such an environment.<\/li><li>Vibration and shock<br \/>These two physical phenomena will cause poor electrical contact in frequency inverter and open welding of components, and will also have a greater impact on the normal use of the inverter. For this reason, daily maintenance and repair work should not be careless.<\/li><\/ul><ol><li><strong>\u00a0Electrical environment<\/strong><\/li><\/ol><ul><li>Prevent electromagnetic interference<br \/>Due to the rectification and inverter links during operation of the frequency inverter, this working process will inevitably produce a lot of electromagnetic wave interference. These high-frequency electromagnetic waves will cause certain interference to nearby instruments and meters. For this reason, instruments and meters on the same network as the frequency converter should be grounded first. Cables with shielding layers should be used for connections between various electrical components and instruments, and the shielding layer must be grounded.<img decoding=\"async\" class=\"aligncenter wp-image-122700 size-full\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation.webp\" alt=\"Necessary conditions for frequency inverter operation\" width=\"1200\" height=\"600\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation.webp 1200w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation-300x150.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation-1024x512.webp 1024w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation-768x384.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2024\/01\/Necessary-conditions-for-frequency-inverter-operation-600x300.webp 600w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/li><li>Prevent input overvoltage<br \/>Although most inverter power input terminals have an overvoltage protection function, if the high voltage at the input terminal of the frequency inverter is applied for a long time, related components inside the inverter (such as varistors, rectifier devices, etc.) will often be damaged. For power supplies with frequent and large voltage fluctuations, consider using voltage stabilizing equipment.<\/li><li>Grounding<br \/>Correct grounding of the frequency converter is an important means to improve system sensitivity and suppress noise interference. The grounding resistance of the frequency inverter grounding terminal G (also marked as E) should be as small as possible. The cross-sectional area of the grounding wire should not be less than 2mm\u00b2, and the length should be controlled within 20m.<\/li><li>Lightning protection<br \/>Inverters are generally equipped with lightning absorption and discharge circuits to prevent instantaneous lightning intrusion from causing damage to the inverter. For this reason, if you are in a lightning active area and the inverter power supply is introduced via an overhead line, a lightning arrester dedicated to the frequency inverter should be installed at the incoming line.<\/li><\/ul><\/div><div>\u00a0<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ff12ac1 elementor-widget elementor-widget-heading\" data-id=\"ff12ac1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Applications of frequency inverter<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6f906da elementor-widget elementor-widget-text-editor\" data-id=\"6f906da\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div style=\"line-height: 40px\"><p>Like <a href=\"https:\/\/www.takomabattery.com\/product\/2000w-pure-sine-wave-inverter\/\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline\"><span style=\"color: #3366ff;text-decoration: underline\">2000w pure sine wave inverter<\/span><\/span><\/a>, frequency inverter is widely used in industrial production, transportation, household appliances and other fields, and have the advantages of energy saving, high efficiency and safety.
