1.2 Safety guide
•After receiving this product, first confirm the product package
is intact. If any question, contact the logistic company or local
distributor immediately.
•The installation and operation of the machine must be carried
out by professional technicians who have received professional
training, and thoroughly familiar with all the contents in this
manual and the safety requirements of the electrical system.
• Do not carry out connection/disconnection, unpacking inspection
and unit replacement operations on the machine when power source
is applied. Before wiring and inspection, users must confirm the
breakers on DC and AC side of inverter are disconnected and wait
for at least 5 minutes.
・Ensure there is no strong electromagnetic interference caused
by other electronic or electrical devices around the installation
site.
• Do not refit the machine unless authorized.
• All the electrical installation must conform to local and
national electrical standards
・Do not touch the housing of the machine or the radiator to avoid
scald as they may become hot during operation
・Ground with proper technical before operation
・Do not open the surface cover of the machine unless authorized.
The electronic components inside the machine are electrostatic
sensitive. Do take proper anti-electrostatic measures during
authorized operation.
• The machine needs to be reliably grounded.
• Ensure that DC and AC side circuit breakers have been
disconnected and wait at least 5 minutes before wiring and
checking.
Note: Technical personnel who can perform installation, wiring, commissioning,
maintenance, troubleshooting and replacement of the energy storage inverters must meet the
following requirements:
•Operators need professional training.
•Operators must read this manual completely, and master the related safety precautions.
•Operators need to be familiar with the relevant safety regulations for electrical systems.
•Operators need to be fully familiar with the composition and operating principle of the entire
energy storage system, and related standards of the countries/regions in which the project is
located.
•Operators must wear personal protective equipment.

1.2.2 Grid-tied operation
* Only qualified electricians are allowed to operate the machine under the
permission of local power departments.
*All electrical connections must meet the electrical standards of the
countries/regions in which the project is located.
*Ensure reliable installation and electrical connection before operation.
*Do not open the cover of the machine when the machine is working or any circuit is
connecting to the machine.
1.2.3 Maintenance and replacement
*Only qualified electricians are allowed to perform the maintenance, inspection, and
component replacement of the machine.
* Please contact the distributor or manufacturer for maintenance.
* In order to avoid irrelevant personnel from entering the maintenance area during
maintenance, temporary warning signs must be placed to warn non-professionals to enter
or use fence for isolation.
*Before carrying out any maintenance operations, all input power to the machine
must be disconnected first, and wait for at least 5 minutes until the internal partsof the
machine are fully discharged.
*Please follow the electrostatic protection norms, and take correct protective
measures because there are mostly electrostatic sensitive circuits and devices in the
machine.
*Do not use parts and components not provided by our company during
maintenance.
*Restart the machine after eliminating the faults and problems which may affect the
safety and performance of the machine.
*Do not get close to or touch any charged metal conductor parts of the grid or
running system, otherwise electric shock or fire may occur. Please do not ignore the
warning icons and instructions with "electric shock".
1.2.4 What to do after scrapping
*Do not dispose of the machine together with household waste. The user has the
responsibility and obligation to send it to the designated organization for recycling and
disposal.
