7 Routine Maintenance

Due to the influence of environment, temperature, dust and vibration,
the devices inside the energy storage system will age and wear out,
leading to the potential failure inside the energy storage system.
Therefore, it is necessary to implement daily and regular maintenance
of the energy storage system to ensure its normal operation and
service life.

All measures and methods to help the energy storage system in a
good working state belong to the scope of maintenance work.

7.1 Security considerations

7.1.1 General safety

Warning

·

Only qualified and authorized personnel can perform maintenance

and other operations on the energy storage system.

·

During maintenance, do not leave the screws, washers and other

conductors in the product, otherwise the equipment may be
damaged!

Warning

After the energy storage system is out of operation, please wait for
at least 15 minutes before carrying out maintenance and other
operations.

7.1.2 Five safety rules

During maintenance or overhaul of the energy storage system,
