Use conditions
★ Maximum and minimum air temperatures are +40°C and -5°C, respectively. Maximum daily average temperature is 35 °C. ★ At a maximum temperature of +40°C, the relative humidity of the air is less than 50%. At lower temperatures, a higher relative humidity is permitted, such as 90% at +20°C, and should take into account the potential for sporadic condensation due to temperature variations. ★ "Indoor installation and use, it's use site's altitude shall not exceed 2000 meters." ★ The vertical surface and the installation of the equipment are not inclined more than 5%. ★ No more than 8 degrees of earthquake intensity. ★ There are no major pollution issues, chemical corrosion issues, fire and explosion risks, or ominous vibrations in the area.Main features
★ High protection level of equipment shell, reaching IP42. ★ The main incoming line and main outgoing line of each functional unit are fixedly connected to improve the reliability of power supply; ★ For the safety of people who use the equipment and to prevent electrical faults from spreading, each functional unit is designated a separate compartment. ★ The cabinet frame is assembled by C-shaped steel bolts, and the compartment size are changed by patterned 25mm, with a high degree of standardization. ★ Low maintenance cost ★ Reliable, flexible and expandable design, saving floor space.Order instructions
