1.Important Safety Precautions
General Information
Please read the "safety precautions" carefully before installing and using this
product to ensure correct and safe installation and use. Please keep this manual
properly.
UPS must be installed, tested and maintained by an engineer authorized by the
manufacturer or its agent, otherwise it is possible to endanger personal safety and
cause equipment failure. The damage to UPS caused thereon is excluded from the
warranty.
Under no circumstances shall equipment structure or components be dismantled
or changed without the manufacturer's permission, otherwise the damage to UPS
caused thereby shall not be covered by the warranty.
Local regulations and laws shall be followed when using equipment. The safety
precautions in the manual only supplement the local safety regulations.
Due to product version upgrade or other reasons, the content of this document
will be updated from time to time. Unless otherwise agreed, this document is used
only as a guide, and all statements, information and recommendations in this
document do not constitute any warranty, express or implied.
UPS Safety
Before installing the equipment, wear insulating protective clothing, use
insulating appliances, and remove conductive objects such as jewelry and
watches to avoid electric shock or burns.
The operating environment has a certain impact on the service life and reliability
of UPS. The environmental requirements set in the manual must be followed
when using and storing the equipment.
Avoid using the equipment in direct sunlight, rain, or in environments with
electrified dust.
When placing UPS, maintain a safe distance around it to ensure ventilation.
During operation of the system, do not block the vent.
Do not allow liquids or other foreign objects to enter into the UPS cabinet or
cabinet.
Before using UPS, check whether the local distribution characteristics are
consistent with the information of the product nameplate.
As UPS is a large leakage current device, it is not recommended to install
breakers with leakage protection function.
Before connecting UPS, please further confirm whether the switch connecting the
power supply of the UPS mains input/bypass power supply and the mains power
are disconnected.
When it is required to move or rewire UPS, make sure to disconnect AC input
power supply, battery and other inputs, and UPS is fully powered down (more
than 5min) before carrying out the corresponding operation, otherwise there may
still be power in the port and inside of the equipment, and it is possible to cause a
risk of electric shock.
Before powering on, please confirm the correct grounding, and check wire
