ESD
The static electricity generated by human bodies may damage the electrostatic-
sensitive components on boards, for example, the large-scale integrated (LSI)
circuits.
● Wear ESD gloves before touching a device or holding a board or PSU.
● When holding a board or PSU, hold its edge without touching any
components. Do not touch the components with your bare hands.
● Package removed boards or PSUs with ESD packaging materials before
storing or transporting them.
1.4 Storage and Installation Environment
Requirements
Storage Requirements
● The total storage and transportation time of the ESS cannot exceed eight
months (starting from delivery).
● The storage environment requirements are as follows:
a. Ambient temperature: 0–40°C; recommended storage temperature: 20–
30°C
b. Relative humidity: 5% to 80%
c. Place the equipment in a dry and clean place with proper ventilation.
d. Keep the equipment in a place that is away from corrosive organic
solvents and gases.
e. Keep the equipment away from direct sunlight.
f. Keep the equipment at least 2 meters away from heat sources.
● The main power loop must be disconnected during storage. It is
recommended that the auxiliary power supply be powered on to ensure that
the monitoring system works properly.
● The temperature and humidity log data, storage environment photos, inspection reports,
and other proof must be available to show that the storage requirements are met.
● Batteries should not be stored or left unused for long periods of time. If a lithium
battery is stored for a long time, capacity loss may occur. After a lithium battery is
stored for 12 months in the recommended storage temperature, the irreversible capacity
loss rate is 3%–10%.
Installation Environment Requirements
● When installing the ESS, comply with the
reproof distance or rewall
requirements specied in local standards, including but not limited to
NFPA
855 Standard for the Installation of Stationary Energy Storage Systems.
