Emerson 208V Manuel D’Utilisation

The Liebert

®

 GXT3

™

-3000RT208 was tested under 20A branch circuit in accordance with the 

National Electrical Code, ANSI/NFPA 70. To reduce the risk of fire, connect only to a circuit provided 

with 20A maximum branch overcurrent protection.

ELECTROMAGNETIC COMPATIBILITY—The Liebert GXT3 complies with the limits for a 

CLASS A DIGITAL DEVICE, PURSUANT TO Part 15 of FCC rules. Operation is subject to the 

following two conditions: (1) This device may not cause harmful interference and (2) this device must 

accept any interference received, including interference that may cause undesired operation. 

Operating this device in a residential area is likely to cause harmful interference that users must 

correct at their own expense.
The Liebert GXT3 series complies with the requirements of EMC Directive 2004/108/EC and the 

published technical standards. Continued compliance requires installation in accordance with these 

instructions and use of accessories approved by Emerson.

UPS Servicing: UPS makes use of components dangerous for the environment (electronic cards, 

electronic components). The components removed must be taken to specialized collection and disposal 

centers.

Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate the batteries. Released electrolyte is toxic and is harmful to skin and 

eyes.
Dispose of used batteries according to the instructions. 

A battery can present a risk of electrical shock and high short circuit current. The following 

precautions should be observed when working on batteries:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is inadvertently grounded. If it is inadvertently grounded, remove 

the source of the ground. Contact with any part of a grounded battery can result in electri-

cal shock. The likelihood of such shock will be reduced if grounds are removed during 

installation and maintenance (applicable to a UPS and a remote battery supply not having 

a grounded supply circuit).
