How can a PLC cabinet be placed in an explosion-proof area, and what about frequency converters?
Thread Content
Could anyone please advise on how to arrange PLC cabinets and frequency converters in an explosion-proof area? Should the cabinets be completely explosion-proof or equipped with positive pressure ventilation? How can heat dissipation be ensured? Are there any suitable cabinet manufacturers you could recommend?
Why put it on site? It’s completely unnecessary; if you must use it, positive pressure ventilation is the best choice! ! ! ! !
It is recommended to use positive pressure ventilation for the PLC cabinets when they are installed on site; there is no need at all to place inverters on site. Your 380V power supply always comes from a non-explosion-proof area, so that’s where the inverter should be placed.
