Safety Precautions
To ensure smooth installation and operation, please read this manual carefully before installing and operating
the Liebert®ITA 6kVA UPS (UPS for short). For detailed product information, refer to the Liebert®ITA 6kVA UPS
User Manual in the VCD delivered with the product.
The UPS must be installed and commissioned by engineers designated by the manufacturer or its agent. Failure
to observe this could result in personnel safety risk, UPS malfunction and invalidation of warranty.
The UPS has been designed for commercial and industrial use only, and is not recommended for use in life
support applications.
This is a Class A UPS product. In a residential environment, this product may cause radio interference, in which
case, the user may be required to take additional measures to reduce the interference.
Note
Non-authorized personnel are prohibited from installing or commissioning the Liebert®ITA 6kVA UPS.
Earth Connection
Warning
Earth connection is essential before connecting the input and output cables. This equipment must be earthed in accordance
with the local electrical regulations.
Maintainable Components
Warning
All internal maintenance and servicing procedures of the equipment should be carried out only by trained personnel with
tools. Components (including the components behind the protective cover) which can only be removed by using a tool are
restricted to service personnel.
The UPS meets the safety requirements completely in operator access area. Only service personnel can touch the
hazardous voltage components inside the UPS and battery module. However, the risk of touching these voltages is
minimized as the components with hazardous voltage may be touched only uses a tool to remove the protective cover. No
risk will exist if you follow the general norms and in accordance with the procedures recommended in this manual on
equipment operation.
Battery High Voltage
Warning
Tools or keys must be used for all batteries maintenance, which should be carried out by trained personnel.
Battery use requires special care. After the battery is connected, the battery terminal will output DC high voltage, and
physical contact would be fatal.
Battery manufacturer provides the precautions to be observed when working on the battery string. These precautions
should be followed implicitly at all times. Particular attention should be paid to the recommendations concerning local
environmental conditions and the provision of protective clothing, first aid and fire-fighting facilities.

Chapter 2 Single UPS Installation And Commissioning
This chapter introduces the single UPS installation, power cable connection and commissioning.
2.1 Installation Preparation
Installation environment
zWell-ventilated; far away from water, heat source, flammables and explosive substances.
zAvoid direct sunlight.
zFree of dust, volatile gas, corrosive materials and excessive salt.
If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter should
be used where the UPS is to operate in a dusty environment.
Installation clearances
The internal fans provide forced air cooling for the UPS. The hot air will be exhausted through the ventilation holes of
the UPS rear panel. Therefore, do not obstruct the ventilation holes.
Maintain at least 200mm clearances between the UPS and the wall or adjacent equipment, so as not to obstruct the
UPS ventilation and heat dissipation. Otherwise, the UPS internal temperature will rise, which will shorten the UPS
life.
Installation tools
zCross head screwdriver (EJ5100mm): Remove the screws of the UPS top plate, or open the chassis.
zSlotted screwdriver (EJ375mm): Connect input and output cables.
zDiagonal plier (MTC3C): Make input and output cables.
zWire-pressure plier (YT-12): Press wires for I/O terminal block.
Unpacking inspection
After the UPS arrival, you should unpack it and check the following items:
1. Visually inspect the UPS appearance for transportation damage. If any problem is found, please notify the carrier
immediately.
2. Check the accessories and models against the delivery list.
2.2 Mechanical Installation
Two installation modes are available: tower installation and rack installation. You can select an appropriate installation
mode according to the actual conditions.
2.2.1 Tower Installation
1. Adjust the display panel.
Note
1. For the tower installation, you need to adjust the display panel; for the rack installation, ignore this step.
2. When adjusting the display panel, there is no need to open the chassis of the UPS.
1) Take off the fixing screws (2 pcs), and hold the left side of the display panel to pull it out.
2) Turn the display panel 90° counter clockwise, and then put it to its original place.
3) Tighten the fixing screws.
