Introduction to the physical environment of the influence of frequency converter used.


1) the operating temperature. High-power inverter is internal electronic components, are highly susceptible to the influence of working temperature, product general requirements of 0 ~ 55 , but work in order to ensure safe, reliable, leave room should be considered when using, the best control under 40 .In the control box, inverter, generally should be installed on the upper box body, and strictly comply with the installation requirements in product specifications, absolutely not allowed to put the heating elements or easily heating element close to the bottom of the frequency converter installation.


2) environmental temperature. When temperature is too high and the temperature change is bigger, frequency converter internal easy appear dewing phenomenon, its insulation performance could be greatly reduced, even may cause short circuit accident. When necessary, must add desiccant and heater in the box.

3) the corrosive gas. Using the environment if the concentration of corrosive gas, not only will the corrosion of components of fuses, printed circuit boards, etc., but also accelerate the ageing of plastic parts, reduce the insulation performance, in this case, should make control box into closed structure, and to take a breath.

4) vibration and shock. Equipped with inverter control cabinet by mechanical vibration and impact, can cause electric contact undesirable. At this time in addition to improve the mechanical strength of control cabinet, away from the vibration sources and impact source, still should use seismic rubber mat fixed outside the control cabinet and the vibration of the components such as electromagnetic switch. Equipment operation after a period of time, to deal with the inspection and maintenance.
