1. Operating temperature. The inverter is a high-power electronic component, which is easily affected by the operating temperature, and the product is generally required to be 0-55 °C, but in order to ensure the safety and reliability of the operation, it should be considered to leave room for use, and it is best to control it below 40 °C. In the control box, the inverter should generally be installed on the upper part of the box, and strictly abide by the installation requirements in the product manual, and it is definitely not allowed to install the heating element or the element that is easy to heat up close to the bottom of the inverter.
2. Ambient temperature. When the temperature is too high and the temperature changes greatly, the inverter is prone to condensation, and its insulation function will be greatly reduced, and it may even cause a short circuit. If necessary, a desiccant and a heater must be added to the box.
3. Corrosive gases. If the concentration of corrosive gas in the application environment is large, it will not only corrode the lead wires and printed circuit boards of the components, but also accelerate the aging of plastic equipment and reduce the insulation function.
4. Oscillation and shock. Control cabinets equipped with frequency converters are subjected to mechanical oscillations and shocks, which can cause poor electrical contact. At this time, in addition to improving the mechanical strength of the control cabinet and keeping it away from the oscillation source and impact source, the anti-seismic rubber pad should also be used to fix the external and internal electromagnetic switches of the control cabinet and other oscillating components. After the equipment has been running for a period of time, it should be inspected and maintained.

Xinjie PLC cable design selection and construction anti-interference measures
(1) The analog signal is a small signal, which is very susceptible to external interference, and a double-layer shielded cable should be selected;
(2) High-speed pulse signals (such as pulse sensors, digital disks, etc.) should be shielded cables, not only to prevent external interference, but also to prevent high-speed pulse signals from low-power.
