Installation

1.0INSTALLATION

The Liebert NX™ UPS is designed primarily for telecommunications and data processing applica- tions. Liebert Corporation neither recommends nor knowingly sells this product for use with life sup- port and other designated “critical” devices.

This section describes the NX’s 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

Special care should be taken when working with the batteries associated with this equipment. When connected together, the nominal battery voltage is 288VDC and is potentially lethal.

•Eye protection should be worn to prevent injury from accidental electrical arcs.

•Remove rings, watches and all metal objects.

•Only use 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.

NOTE

The NX UPS can be used in TN utility system.

1.1External Inspections

1.While the UPS system is still on the truck, inspect the equipment and shipping container(s) for any signs of damage or mishandling. Do not attempt to install the system if damage is apparent. If any damage is noted, file a damage claim with the shipping agency within 24 hours and contact Liebert Global Services at 1-800-LIEBERT to inform them of the damage claim and the condition of the equipment.

2.Compare the contents of the shipment with the bill of lading. Report any missing items to the carrier and your local Liebert representative immediately.

1.2Internal 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.

3.Check for loose connections or unsecured components in the cabinet.

4.Check for shipping damage to internal components.
