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.
