Terms of use
Ambient air temperature should not exceed 40°C and not be lower than -5°C. The average temperature within 24 hours must not exceed 35°C.
For indoor installation, the elevation of the site must not exceed 2000m.
The relative humidity of the surrounding air should not exceed 50% at a maximum temperature of 40°C, and higher relative humidity is allowed at lower temperatures. (For example, 90% at 20°C) should be taken into account
Temperature changes may occasionally cause condensation.
When installing the equipment, the tilt relative to the vertical plane should not exceed 5°.
Equipment should be installed in locations free from severe vibration and impact, and where electrical components cannot be corroded.
If the user has special requirements, they can be resolved through consultation with the manufacturer.
