Emaldo Power Core User Manual
11
Copyright©EMALDO
immediately, call the police in time, contact the professional, and the professional will use
fire-fighting facilities to extinguish the fire under the condition of ensuring safety.
• After the battery drops, if there is no obvious deformation or damage in appearance and
there is no obvious odor, smoke or fire, contact a professional to transport the battery to an
open and safe place or contact a recycling company for treatment.
Battery recycling
• Please dispose of waste batteries according to local laws and regulations, and do not treat
batteries as domestic garbage. Improper disposal of batteries may lead to environmental
pollution.
• If the battery leaks or is damaged, contact technical support or battery recycling company

obtain better performance. The heating process will consume rechargeable power, which
means that the energy efficiency of the system will be reduced in a short time.
• If the system is stored in a cold environment (for example, 0°C) before installation, it will

Emaldo Power Core User Manual
13
Copyright©EMALDO
take some time (< 2h) for the energy storage system to be heated before charging. It is
recommended to put it in a warm place before installation to help the effective adjustment
and test.
• When the ambient temperature is over 45℃or below -10℃, the charging and discharging
power of the battery will be reduced.
• In the places with frequent natural disasters such as flood, debris flow, earthquake and
typhoon, corresponding preventive measures should be taken for installation.
• The installation location is far away from fire source and heat source, so please do not
place inflammable and explosive articles around the equipment.
• Avoid water accumulation in the installation position, keep away from water sources such
as faucet, sewer pipe and sprinkler, and avoid water seepage.
• When the equipment is running, the outlet temperature of the cabinet will be high, so
please do not install it in an easy-to-touch position.
• When the equipment is running, please do not block the vent or cooling system to prevent
high temperature from causing fire.
• Do not place the equipment in an environment of inflammable and explosive gas or
smoke, and do not carry out any operation in this environment.
• Do not install the equipment in moving scenes such as ships, trains and trucks.
• Do not use the power supply for the following purposes in the standby power scenario.
a. Medical equipment directly related to human life.
b. Control equipment such as trains and elevators, which may cause personal injury.
c. Computer systems of social and public importance.

15
Copyright©EMALDO
resulting in death, serious personal injury or serious property loss. Therefore, before any
maintenance work, the equipment must be powered down and operated in strict accordance
with the safety precautions listed in the Manual and other related documents.
• Maintain the equipment under the condition that you are familiar with and understand the
contents of the Manual and have suitable tools and testing devices.
• Before maintenance, first power down the equipment, and then follow the instructions of
the delayed discharging label and wait for the corresponding time to ensure that the
equipment is powered down before operating the equipment.
• During maintenance, try to avoid irrelevant personnel from entering the maintenance site.
