Safety instructions

energy storage inverter is designed and tested in strict accordance with relevant international safety standards.

Its installation, trial operation, operation and maintenance should comply with safe operation specifications of electrical and electronic equipment.

Incorrect use or wrong operation might endanger operator or a third party and destroy the inverter or other properties.

To prevent the above circumstances from happening, the following precautions should be strictly abided by in the process of operation and maintenance.

The detailed description will be provided in relevant chapter.

Warning
All installation, debugging and maintenance should be completed by professionals. Professionals should:

be approved engineer by the factory or its agent; be professionally trained;
fully read this manual and learn about safe operation matters for electrical and electronic equipment;
be familiar with relevant safety specification of electric system.

Professionals who meet the above conditions shall be capable to:

Install the inverter onto the wall;
Setup energy storage system as per customer’s requirement;
Conduct trial operation of energy storage system;
Operate, debug and maintain energy storage system.

Danger
Equipment wrong operation might cause injury!

Removal and placement of the inverter should abide by the description in this manual.
Improper equipment operation might cause electric shock, burn or contusion.
Any system (equipment) damage caused by modification and disassembly without permission does not fall into the warranty scope.

DANGER
Before inverter installation, ensure that the inverter does not have any electric connection.

CAUTION
Poor ventilation for installation will weaken the system performance!

During equipment operation, the ventilation should be good. The equipment should be upright, and there should be no strong air current to prevent airflow so as to ensure that the device is cooled well.

DANGER
Be careful in electric connection. There is dangerous voltage between the two poles of storage battery. Don’t touch the metal terminal when there is no sufficient protection.

CAUTION
The cables used in energy storage system must be connected firmly and with good insulation and proper specification.

CAUTION
All electrical installations should meet national/regional electrical standards;

Grid-tied operation can be conducted after permission is obtained from local national/regional electric power department. Before power-on, please ensure that it is reliably grounded and the grounding meets local electrical standards.

DANGER
Any contact with copper bar, uncovered contact spot or terminal inside the device that is connected to the loop of power grid might result in burning or fatal electric shock.

Don NOT touch any terminal and conductor connected with the power grid.
Pay attention to any instruction and safety documents about grid connection.

WARNING
There might be an electric shock risk inside the device! When the inverter operates or is electrified, don’t open the enclosure of the inverter.

Only intact and closed cabinet can protect operator’s personal and property safety.
Any operation related to this device will be conducted by professionals.
Pay attention to the safety precautions listed in this manual and other documents.

When AC of the inverter is loaded, DC disconnection is not allowed. If disconnection is required, inverter stopping operation should be conducted first. After the AC load isolation switch of the inverter is disconnected and it is confirmed that there is no voltage at the AC terminal of the inverter, DC connection can be turned off.

CAUTION
During inverter operation, the ventilation duct must not be blocked.

Safety instructions for maintenance and replacement

DANGER
Improper equipment maintenance and operation might cause personal injury or equipment damage. Before any operation, users should strictly abide by the following steps:

Disconnect the AC isolation switch between the power grid and the inverter, and then turn off DC breaker of the battery box.
Wait for at least 10 minutes until internal energy storage elements are discharged off. During this period, don’t touch equipment terminal, contact spot, copper bar and other electric parts with body or conductor.
Use detecting device to check and ensure that there are no voltage and current on the device.

CAUTION
Stop irrelevant personnel from entering the maintenance site!
During electrical connection and maintenance, temporary warning signs should be pasted and barriers should be set up to prevent irrelevant personnel entering electrical connection or maintenance area.

CAUTION
The inverter can be restarted only after its malfunction affecting safety performance is removed.
Power can be supplied again after the inverter is fully disconnected for 1 minute.
There are no serviceable parts in the inverter. If any maintenance is required, please contact our after-sales personnel.

CAUTION
Don’t replace the internal elements at will. Otherwise, our company will not undertake any quality guarantee and joint liability for any losses caused thereby.

CAUTION
Components might be damaged by any contact with PCBs or other electrostatic sensitive components or improper operation.

Don’t touch the circuit boards.

Abide by electrostatic protection specifications and wear anti-static wrist strap.

WARNING
Safety signs, warning label and nameplate on the inverter:

Must be clearly visible;
Should not be removed or covered.

Energy storage inverter must be debugged and maintained by the engineers designated by the manufacturer or its agent. Otherwise, it might endanger personal safety and result in device fault. Any damage against the device caused thereby will not fall into the warranty scope.

Energy storage inverter is only used for commercial/industrial purposes, and it cannot be used as an energy saving device related to life support device.

The label on enclosure contains important information for safe operation to the inverter. Don NOT tear down or damage it. The label on enclosure should be clear and readable. If it is damaged or becomes vague, please replace it.
