Installation precautions
Installation condition of electric cabinet
When design the electric cabinet, the distance between the rear cover and the case should be at least
20cm. It should be noted that the temperature difference between the inside and outside of the cabinet
shouldn’t exceed 10
℃
when the temperature inside the electric cabinet rises.
The electric cabinet should be able to prevent the entering of dust, cooling liquid and organic solution.
The electric cabinet should be equipped with fan to ensure internal air circulation.
The display panel should be installed at the place that the cooling liquid can’t spray on.
