Single Module UPS Installation

1.0SINGLE MODULE UPS INSTALLATION

1.1Introduction

This following section describes the requirements that must be taken into account when planning the positioning and cabling of the Liebert NX uninterruptible power supply and related equipment.

This chapter is a guide to general procedures and practices that should be observed by the installing engineer. The particular conditions of each site will determine the applicability of such procedures.

! WARNING

Professional Installation Required

Do not apply electrical power to the UPS equipment before being authorised to do so by the commissioning engineer.

The UPS equipment shall be installed by a qualified electrical tradesperson in accordance with the information contained in this manual. All equipment not referred to this manual is shipped with details of its own mechanical and electrical installation.

NOTE

Three-phase, 4-wire input supply required.

The standard Liebert NX UPS is suitable for connection to 3-phase, 4-wire (+ Earth) TN, TT and IT AC power distribution systems (IEC60364-3). Optional 3-wire to 4-wire conversion transformers are available. If it is used in IT AC power distribution systems, a 4-pole circuit breaker must be used on the input and refer to the relative IT Systems’ standard

! WARNING

Battery Hazards

Special care should be taken when working with the batteries associated with this equipment. When connected together, the battery terminal voltage will exceed 400VDC and is hazardous.

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 the skin, the affected area should be washed immediately with water.

1.2Preliminary Checks

Before installing the UPS, please carry out the following preliminary checks:

1.Visually examine the UPS and battery equipment for transit damage, both internally and externally. Report any damage to the shipper immediately.

2.Verify that the correct equipment is being installed. The equipment supplied has an identification tag on the back of the main door reporting: the type, size and main calibration parameters of the UPS.
