Conditions of use of outdoor control boxes

2022-08-11

1. When using the control box outdoors, the ambient temperature should not be higher than 40 degrees Celsius, the average temperature within 24 hours should not exceed 35 degrees Celsius, and the change limit of the outdoor ambient air temperature can only be reduced by 5 degrees Celsius. The temperature has a great influence on the use of the control box. Once the temperature is too high, it will affect the work of the equipment and even bring fire danger.

2. The humidity of the air is also one of the issues that need to be paid attention to. When using the control box outdoors, the relative humidity of the environment is 40 degrees Celsius and cannot exceed 50%. When the temperature is lower, it is allowed to have a higher humidity, for example, 20 degrees Celsius, and the humidity can be 90%, because moderate condensation will occur in the temperature change, so that the environment can reach a certain balance.

3. The environmental pollution level is level 3. The more serious the environmental pollution is, the more serious the environmental pollution will lead to problems with the cable lines inside the equipment. Due to the serious pollution contained in the air, the long-term use of the cable will cause an oxidation reaction, thereby affecting the environmental quality.

4. The altitude of the installation site cannot be higher than 2000 meters, because the higher the altitude, the thinner the air, and the higher the concentration of substances in the air. At the same time, because of the change of altitude, the magnetic field will also be different, which will affect the electrodes, resulting in different currents and voltages. 

5. Vertical installation on the ground, not too inclined, the inclination should not exceed 5 degrees, otherwise it will cause the outdoor control box to fall. When installing, pay attention to choosing a place with a flat ground to avoid the control box being in a dangerous state.

6. It is not suitable to install the outdoor control box in places with severe vibration and shock, because it will affect the work of the internal components of the outdoor control box, resulting in that the outdoor control box cannot meet the work needs of the enterprise.
