1.0SINGLE-MODULE MECHANICAL INSTALLATION

1.1Introduction

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

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

! WARNING

Risk of electrical shock. Can cause injury or death.

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

NOTICE

All equipment not referred to in this manual is shipped with details of its own mechanical and electrical installation.

NOTICE

Three-phase input supply required.

The standard Liebert NXL UPS is suitable for connection to three-phase, four-wire (+ Earth) TN-C, TN-S, IT-G, IT-IG or, three-phase, three-wire plus ground, IT-UG.

If using with IT Power system, a 4-pole disconnect device must be included as part of building installation.

NOTICE

Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.

1.2Preliminary Checks

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

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

•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.

•Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification, paying particular attention to the ambient temperature and air exchange system.

1.3Environmental Considerations

1.3.1UPS Room

The UPS module intended for indoor installation and should be located in a cool, dry, clean-air envi- ronment with adequate ventilation to keep the ambient temperature within the specified operating range (see Environmental Parameters in Table 6).

The Liebert NXL UPS is cooled with the aid of internal fans. To permit air to enter and exit and pre- vent overheating or malfunctioning, do not cover the ventilation openings.

The Liebert NXL UPS is equipped with air filters located behind the front doors. A schedule for inspection of the air filters is required. The period between inspections will depend upon environmen- tal conditions.

When bottom entry is used, the conduit plate must be installed.

NOTE

The UPS is suitable for mounting on concrete or other non-combustible surface only.
