Service Environment
1. Ambient temperature: -5ºC~+40ºC, and the average temperature within 24 hours does not exceed +35ºC.
2. Altitude: no more than 2000m.
3. Relative humidity: no more than 50% when the ambient air temperature is +40ºC; At lower temperatures there can be higher relative humidity (e.g. 90% at +20 ° C), allowing for moderate condensation taking into account the change in temperature.
4. The inclination of the vertical plane when the equipment is installed should not exceed 5%.
5. The equipment should be installed in a place without severe vibration, impact and corrosion.
Note: Beyond the above conditions, you can negotiate with our company.
