NSTALLATION
This section describes the Liebert NX environmental requirements and mechanical considerations
that must be taken into account when planning the positioning and cabling of the UPS equipment.
Because every site is unique, this section presents a guide to general procedures and practices that
should be observed by the installing engineer, rather than step-by-step installation instructions.
WARNING
!
Do not apply electrical power to the UPS equipment before the arrival of the commissioning
engineer.
WARNING
!
The UPS equipment should be installed by a qualified engineer in accordance with the
information contained in this section.
WARNING
!
Risk of electric shock. Can cause injury and death.
Special care should be taken when working with the batteries associated with this equipment.
When connected together, the nominal battery voltage is 480VDC and is potentially lethal.
• Eye protection should be worn to prevent injury from accidental electrical arcs.
• Remove rings, watches and all other metal objects.
• Use only tools with insulated handles.
• Wear rubber gloves.
If a battery leaks electrolyte or is otherwise physically damaged, it must be replaced, stored in
a container resistant to sulfuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with skin, the affected area should be washed immediately
with large amounts of water.

Internal Inspections
1. Remove any packaging material, then visually examine the UPS and battery equipment for
transit damage, both internally and externally. Report any such damage to the shipper and to
Liebert immediately.
2. Check the nameplate inside the cabinet door to verify that the model number and rating
correspond to the ones specified. Record the model number and serial number in the front of this
installation manual. This information is necessary should service be required.
