The atmospheric corrosion environment is defined and classified according to
the natural environment state, and the A/B environment is defined as follows:
A: environment refers to the ocean or the land near the pollution source, or
the environment with simple shelter (such as awning). "Near the ocean" refers to the
area 0.5～3.7km away from the ocean; "Near the pollution source" refers to the area
within the following radius: 3.7km from the saltwater lake, 3km from heavy pollution
sources such as smelters, coal mines, and thermal power plants, chemical industry,
rubber, electroplating, etc. 2km from medium pollution sources such as chemical
industry, rubber and electroplating, etc. And 1km from light pollution sources such as
food, leather and heating boilers, etc.
B: environment. Refers to the environment on land or outside with simple
shelter (such as awning) within 500m from the coast, or the environment on the sea.
days@25°C, 15 days@45°C. The battery needs to be recharged in time after storage,
otherwise the battery may be damaged due to over-discharge, and the entire battery
pack needs to be replaced.
The following conditions may cause the battery pack to be stored in a
discharged state:
After the utility power failure, the line/fault cannot be eliminated in time, and
the power supply cannot be restored for a long time.
After the installation and commissioning work is completed, the utility power
is turned off directly, but the battery pack is not powered off, which will cause the
battery to enter the low power consumption mode.
Other reasons cause the battery pack to fail to enter low power consumption
normally.
4 Application Description
4.4 Application of Nearing the Ocean
The battery pack can be used under other environmental conditions and cannot
be used alone under A/B environment. If it is to be used in the A/B environment, it
needs to be equipped with a high-protection air-conditioning cabinet, which is
recommended to be IP55 or higher.
