Manual

7.Maintenance and replacement
◆ Please maintain the equipment when you are familiar with and understand the
contents of this manual and have appropriate tools and test devices.
◆ Before carrying out maintenance work, please power down the equipment first,
then follow the instructions of the delayed discharge label and wait for the
corresponding time to ensure that the equipment has been powered down before
operating the equipment.
◆ During maintenance, please try to avoid irrelevant personnel entering the
maintenance site, and temporary warning signs or fences must be erected for
isolation.
◆ If the equipment fails, please contact your dealer in time.
◆ The equipment can be powered on again only after the fault is handled, otherwise it
may cause fault expansion or equipment damage.
◆ Do not open the cover plate without authorization, otherwise there will be a risk of
electric shock, and the resulting failure does not belong to the scope of warranty.
◆ Operation and maintenance personnel and professional technicians shall be fully
trained in safe use and equipment maintenance, and shall operate with sufficient
preventive measures and personal protective equipment.
◆ Battery maintenance shall be performed or super vised by personnel familiar with the
batter y and its required precautions.
◆ After the maintenance operation, check immediately to ensure that no tools or other
parts are missing in the equipment.
8.Battery storage requirements
◆ When the battery is stored, it shall be placed correctly according to the identification
of the packing box, and shall not be placed upside down or on the side.
◆ When the battery packing box is stacked, it shall meet the stacking requirements on
the outer package.
◆ The battery shall be handled with care, and it is strictly prohibited to damage the
batter y.
◆ Storage environment requirements:
a. Ambient temperature: - 10 ? ~ 55 ?, recommended storage temperature:
20 ? ~ 30 ?.
b. Relative humidity: 35% RH ~ 85% RH.
c. Dry, ventilated and clean.
d. Avoid contact with corrosive organic solvents, gases and other substances.
e. Avoid direct sunlight.
f. The distance from the heat source shall not be less than two meters.
◆ When the battery is stored, it must be disconnected from the outside. If there is an
indicator on the battery panel, the indicator should be off.
◆ The warehouse keeper shall count the batter y storage every month and regularly
report the battery inventory to the planning link. For batteries with storage time close
to - 20 ~ 25 ? = 6 months and - 20 ~ 45 ? = 1 month, replenishment shall be arranged
in time. The battery shall be charged once every three months (under the normal storage
environment, long-term storage will lead to capacity attenuation and cycle life decline.
If it exceeds the storage environment requirements, it will further aggravate the capacity
attenuation and cycle life decline.)
◆ When the stored batteries are shipped, the principle of first in first out shall be followed.
