Working And Installation Conditions

1.Normal working conditions: -5~40°C For -40°C ~-5°C, 40°C ~70°C,
2.If the working environment temperature exceeds 40°C, please refer to the temperature derating coefficient table for use; Storage temperature: -40~70°C (If the storage temperature is lower than normal working conditions, the product should be returned to working conditions and left to stand for at least 24 hours before being put into use);
3.Normal operating humidity: When the ambient air humidity is +40°C, the relative humidity of the atmosphere cannot exceed 50%; if the temperature is lower, it can be used under higher relative humidity conditions;For example: at +20°C, it reaches 90%.
