CAUTION
Carefully read the following safety notices. Failure to observe the instructions may endanger
your life, your health, the reliability of your device and the security of your data.
• Transport the unit only in suitable packaging (protected against jolts and shocks).
• If the equipment is moved from a cold environment to the operating room, condensation
may occur. Before you switch On the equipment, it must be absolutely dry. An acclimatiza-
tion period of at least two hours is required.
• The equipment must be installed in accordance with the environmental conditions specified
in
2.6 - Environmental Conditions
and in
Table 11 - Environmental data
.
• Even with all switches in the “OFF” position (see
Figure 13 - Control panel
) the UPS is
not isolated from the mains. To isolate completely from the mains, the power cables must be
disconnected.
• In case of interruption of the mains 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
2.0 - Unpacking the UPS and Site
Preparation
.
• Make sure that no objects (e.g., pins, necklaces, paper clips, etc.) get inside the device.
• 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 represen-
tative.
• 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. Earth connection is essential
before connecting supply.
• Data transmission lines should not be connected or disconnected during a thunderstorm.
• Remote Emergency Power Off (REPO) input is located on the rear of the unit (see
3.8 - Ter-
minal Blocks for UPS
). When this connection is open, the logic circuit will immediately
shut down the UPS output.
• An Emergency Switching Device (E.S.D.) must be fitted downstream of the UPS for the wir-
ing installation safety to comply with the European Harmonized Document HD384-4-46 S1.
• Maintenance bypass switch is for the use of service personnel only. It is located under the
rear cover. Open the safety cover to operate the maintenance bypass switch.
• The Tower UPS may be connected either to 3-phase mains or single-phase mains. Therefore
the right input terminals have to be connected (see
3.7 - Connecting Mains and Load
).
The UPS autosensing mode ensures that it adapts to the connected mains supply.
• This equipment complies with IEC 61000-3-12 provided that the short-circuit ratio Rsce is
greater than or equal to 250 at the interface point between the user’s supply and the public
system. It is the responsibility of the installer or user of the equipment to ensure, by consul-
tation with the distribution network operator if necessary, that the equipment is connected
only to a supply with a short-circuit ratio Rsce greater than or equal to 250.
• For three-phase equipment, the disconnect device shall disconnect simultaneously all line
conductors of the AC mains supply. For equipment requiring a neutral connection to an IT
power distribution system, the disconnect device shall be a four-pole device and shall dis-
connect all line conductors and the neutral conductor.
!
CAUTION
Do
not
connect more than four Liebert GXT3-240TBATTCE battery extensions to the Liebert
GXT3-10000T230. This also applies when the additional battery charger is connected.
The vents for air intake and outlet at the front and rear side must not be obstructed.
The sum of the leakage currents (protective conductor current) of the UPS and the connected
devices exceeds 3.5 mA. Earth connection of the unit is essential before connecting supply.
