 Working conditions:

• Can withstand the effects of humid air(Temperature @+40℃ and above, air relative humidity does not exceed 50%,allows greater relative humidity at lower temperatures,for example,95%@+20℃)
• Can withstand salt spray for 48 hours
• In a medium without explosion hazard, and the medium does not have enough gas and conductive dust to corrode metal and destroy insulation
• In places where there is no rain or snow
• Height:≤2000m,if you want to apply it more than 2000m, you must refer to Miniature

Packaging and storage:

• Maximum number of package:8/box, packed in boxes:24 boxes/box, it should stored in a warehouse where air circulation and relative humidity is not more than 80%, temperature is not lower than -40℃ but not higher than 80℃. Store in the warehouse without acid,alkaline or other corrosive gases in the surrounding air.
• Under the above conditions, the storage period shall not exceed 1 year from the date of manufacture.
