Liebert 3000VA 사용자 설명서

This manual contains important safety instructions that must be followed during the installation and 

maintenance of the UPS and batteries. Read this manual thoroughly before attempting to install or 

operate this UPS.

The UPS contains no user-serviceable parts except the internal battery pack. Do not remove the 

cover. Removing the cover may result in electric shock and will invalidate any implied warranty.
The UPS has an internal battery, so the output receptacles of the UPS may carry live voltage even if 

the UPS is not connected to mains input power.
Before moving or rewiring the UPS, disconnect mains input power and the battery and make sure 

that the UPS is completely shut down. Otherwise, the output terminal may carry live voltage, 

presenting an electric shock hazard.
To ensure human safety and normal UPS operation, the UPS must be properly grounded before use.
When the UPS is connected to an IT power distribution system, the short-circuit protection device 

must be installed on the neutral line.
Install and use the UPS in the following environments:

• Temperature: 0°C to 40°C (32 - 104°F); relative humidity: 0% to 95%, non-condensing)
• Out of direct sunlight
• Away from heat source
• Stable surface, not subject to vibrations or shocks
• Away from dust and other particulates
• Away from corrosive substances, salts and flammable gases

Keep the air inlet and outlet of the UPS unobstructed. Poor ventilation will increase the UPS internal 

temperature and can shorten the life of the UPS and its batteries.
Keep liquid and other foreign objects away from the UPS.
In case of fire, use a dry chemical fire extinguisher to put out the fire. Using a fluid fire extinguisher 

may cause electric shock.
This UPS is not intended for use with life support and other designated critical devices. Maximum 

load must not exceed that shown on the UPS rating label. This UPS is designed for data processing 

equipment. If uncertain, consult your local dealer or Emerson Network Power

®

 representative.

Observe all cautions and warnings in this manual. Failure to do so may result in serious 

injury or death.
Refer all UPS and battery service to properly trained and qualified service personnel. Do not 

attempt to service this product yourself.
Opening or removing the cover may expose you to lethal voltages within this unit even when 

it is apparently not operating and the input wiring is disconnected from the electrical source.
Never work alone.
