Danger
Lethal voltage!
⚫Battery strings will produce HIGH DC power and can cause a
lethal voltage and an electric shock.
⚫Only a qualified person can perform the wiring of the battery
strings.
Warning
Risk of battery system damage or personal injury
⚫DO not pull out the connectors while the system is working!
⚫De-energize from all power sources and verify that there is no
voltage.
Caution
Risk of battery system failure or life cycle reduction.

Danger: Batteries deliver electric power, resulting in burns or fire hazard when they are short
circuited, or wrongly installed.
Danger: Lethal voltages are present at the battery terminals and cables. Severe injuries or death
may occur if the cables and terminals are touched.
Warning: DO NOT open or deform the battery module, otherwise the product will be out of
warranty scope
Warning: Whenever working on the battery, wear suitable personal protective equipment (PPE)
such as rubber gloves, rubber boots and goggles.
Warning: The AXIstorage Li SV2 system’s working temperature range: 0℃～50℃; Optimum
temperature: 18℃～28℃.Conditions out of the working temperature range may cause
the battery system over / low temperature alarm or protection which further leads to a
cycle life reduction as well as it will affect the warranty terms.
Warning: For battery installation, the installer shall refer to NFPA70 or similar local installation
standard for operation.
Caution: Improper settings or maintenance can permanently damage the battery.
Caution: Incorrect inverter parameters will lead to a further faulty/damaged battery.
Reminding
1) It is very important and necessary to read the user manual carefully before installing or
using the battery. Not doing so or not to follow any of the instructions or warnings in this
document can result in electrical shock, serious injury, or death, or can damage the
battery, potentially rendering it inoperable.
2) If the battery is stored for a long time, it is required to charge them every six months, and
the SOC should be no less than 90%;
3) Batteries need to be recharged within 12 hours, after full discharge;
4) Do not expose cable outside;

1.2 Before Connecting
1) After unpacking, please check the product and packing list first. If a product is damaged
or if there is a lack of parts, please contact the local retailer;
2) Before installation, be sure to cut off the grid power and make sure the battery is in the
switched-off mode;
3) Wiring must be correct, do not mistake the positive and negative cables, and ensure there
is no short circuit with the external device;
4) It is prohibited to connect the battery to AC power directly;
5) The Battery system must be well grounded, and the resistance must be less than 100mΩ;
6) Please ensured the electrical parameters of the battery system are compatible to the
related equipment;
7) Keep the battery away from water and fire.
1.3 While Using
1) If the battery system needs to be moved or repaired, the power must be cut off and the
battery is completely shut down;
2) It is prohibited to connect the battery with a different type of battery.
3) It is prohibited to use the batteries with a faulty or incompatible inverter;
4) It is prohibited to disassemble the battery (QC tab removed or damaged);
5) In case of fire, only dry powder fire extinguisher can be used, liquid fire extinguishers are
prohibited;
