Introduction
The product must not be disposed of in household waste;
Dispose of it through environmentally friendly collection centres.
Setting of Warning Sign for Safety
While instructing, maintaining and repairing, in case of preventing unrelated personnel
nearby to cause incorrect operation or accident, the opinions below should be followed:
Obvious signs should be set at front switch and rear-level switch in case of accidents
caused by false switching.
Warning signs or tapes should be set near operating areas.
The system must be reinstalled after maintenance or operation.
Measuring Equipment
For ensuring the electrical parameters to match requirements, related measuring
equipment are required when the system is being connected or tested.
Ensure that the connection and use matches specification in case of electric arc or shock.
Moisture Protection
It is very likely that moisture may cause damages to the system.
Repair or maintaining activities in wet weather should be avoided or limited.
Operation After Power Failure
The battery system belongs to energystorage system, and it keeps fatal high voltage even
the DC side is disconnected. Therefore, touching the output of the battery is strictly
prohibited.
The Inverter maintains fatal voltage even both the DC or AC side are disconnected, so it
must be tested by multimeter for safety before operation.
Battery Safety Datasheet

Introduction
Other hazards
This product is a Lithium Iron Phosphate Battery with certified compliance under the UN
Recommendations on Transport of Dangerous Goods, Manual of Tests and Criteria, Part
III, sub-section 38.3. For the battery cell, chemical materials are stored in a hermetically
sealed metalcase, designed to withstand temperatures and pressuresencountered during
normal use. As a result, during normal use, there is no physical danger of ignition or
explosion and chemical danger of hazardous materials' leakage. However, if exposed to a
fire, added mechanical shocks, decomposed, added electric stress by misuse, the gas
release vent will be operated. The battery cell case will be breached at the extreme.
Hazardous materials may be released. Moreover, if heated strongly by the surrounding fire,
acrid or harmful fume may be emitted.
1.3.8.2 Safety Datasheet
The detailed information please refer to the provided battery safety datasheet, which is
provided with the battery product.
General Precautions
WARNING
Risk of chemical burns from electrolyte or toxic gases.
During standard operation, no electrolyte shall leak from the battery pack and no toxic gases shall
form. Despite careful construction, if the Battery Pack is damaged or a fault occurs, it is possible that
electrolyte may be leaked or toxic gases formed.
Do not install the system in any environment of temperature below -10°C or over 50°C and
in which humidity is over 85%.
Do not touch the system with wet hands.
Do not put any heavy objects on top of the system.
Do not damage the system with sharp objects.
Do not install or operate the system in potentially explosive atmospheres or areas of high
humidity.
Do not mount the inverter and the battery pack in areas containing highly flammable
materials or gases.
If moisture has penetrated the system (e.g. due to a damaged enclosure), do not install or
operate the system.
Do not move the system when it is already connected with battery modules.
