Liebert GXT3-10000T220 instruction

! WARNING

Although the Liebert® GXT3™ has been designed and manufactured to ensure safety, improper use can result in electrical shock or fire. To ensure safety, observe the following precautions:

•Turn Off and isolate the Liebert GXT3 before cleaning it. Use only a soft cloth; never use liquid or aerosol cleaners.

•Never block or insert any objects into the ventilation holes or other openings of the UPS.

•Do not place the Liebert GXT3 power cord where it might be damaged.

!CAUTION

•When installed in EU countries, the Liebert® GXT3-10000T220™is not intended to operate with isolated neutral (IT systems). Neutral connector must be present and connected to the UPS.

•Even with all buttons OFF (see 4.2 - Control Panel) the device (UPS) is not isolated from the utility. To isolate completely from the utility, the power cables must be disconnected.

•In case of interruption of the utility voltage, the integrated battery maintains the power supply to the user equipment.

•Lay all cables so that nobody can stand on them or trip over them. When connecting the UPS to the power supply, follow the instructions in 3.0 - Installation.

•In emergencies (e.g., damaged case, controls or power cables, penetration of liquids or for- eign matter), switch off the device and contact the appropriate customer service representa- tive.

•Do not connect equipment that will overload the UPS (e.g., laser printers or vacuum clean- ers) or demand DC-current (e.g., half-wave rectifiers).

•When cleaning the unit, follow the instructions in 5.0 - Maintenance.

•The sum of the leakage currents (protective conductor current) of the UPS and the con- nected devices exceeds 3.5 mA for all ratings of the UPS. Ground (earth) connection is essential before connecting supply.

•Data transmission lines should not be connected or disconnected during a thunderstorm.

•Emergency Power Off (EPO) input is on the rear of the unit (see 6.4 - Remote Emergency Power Off and 3.6 - Terminal Blocks for UPS). When this connection is open, the logic circuit will immediately shut down the UPS output.

•When installed in EU countries, an Emergency Switching Device (E.S.D.) must be fitted downstream of the UPS for the wiring installation safety to comply with the European Har- monized Document HD384-4-46 S1.

•Maintenance bypass breaker is for the use of service personnel only. The breaker is on the rear of the unit. To operate the breaker, the captive screw must be loosened and the guard must be lifted out of position.
