IMPORTANT SAFETY INSTRUCTIONSSAVE THESE INSTRUCTIONSThis manual contains important instructions that should be followed during installation of your Liebert NXL Power-Tie Controls. Read this manual thoroughly, paying special attention to the sections that apply to your installation, before working with the unit. Retain this manual for use by installing personnel.

NOTICEThis unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of the FCC rules. These limits provide reasonable protection against harmful interference in a commercial environment. This unit generates, uses and radiates radio frequency energy and, if not installed and used in accordance with this instruction manual, may cause harmful interference to radio communications.

WARNINGRisk of electrical shock. Can cause personal injury or death.Only properly trained and qualified personnel wearing appropriate safety headgear, gloves, shoes and glasses should be involved in installing the modules or preparing the modules for installation. When performing maintenance with any part of the equipment under power, service personnel and test equipment should be standing on rubber mats.In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or those approved for use in fighting electrical fires.Extreme caution is required when performing installation and maintenance.Special safety precautions are required for procedures involving handling, installation and maintenance of the UPS system. Observe all safety precautions in this manual before handling or installing the module. Observe all precautions in the Operation and Maintenance Manual before as well as during performance of all maintenance procedures.

WARNINGRisk of electrical shock and fire. Can cause equipment damage, personal injury or death.

Under typical operation and with all doors closed, only normal safety precautions are necessary. The area around the system should be kept free of puddles of water, excess moisture and debris.

Only test equipment designed for troubleshooting should be used. This is particularly true for oscilloscopes. Always check with an AC voltmeter to ensure safety before making contact or using tools. Even when the power is turned Off, dangerously high potential electric charges may exist at the capacitor banks.

All wiring must be installed by a properly trained and qualified electrician. All power and control wiring must comply with all applicable national, state and local codes.

One person should never work alone, even if all power is disconnected from the equipment. A second person should be standing by to assist and to summon help in case of an accident.

NOTEMaterials sold hereunder cannot be used in the patient vicinity (e.g., use where UL, cUL or IEC 60601-1 is required). Medical applications, such as invasive procedures and electrical life-support equipment, are subject to additional terms and conditions.

Operation of this unit in a residential area may cause harmful interference that the user must correct at his own expense.


1.0 MECHANICAL INSTALLATION

1.1 IntroductionThe Liebert NXL Switchgear provides continuous, high-quality AC power to your business-critical equipment, such as telecommunication and data processing equipment. Liebert NXL UPS’s will supply power that is free of the disturbances and variations in voltage and frequency common to utility power, which is subject to brownouts, blackouts, surges and sags.The Liebert NXL Power-Tie system provides manually initiated, uninterrupted transfers of a critical load bus between the two UPS systems.This topology permits one UPS and its associated distribution system to be shut down for maintenance while the load continues to be supplied by another UPS, without the necessity of transferring the load to bypass during shutdown or restart of the UPS being maintained.

1.2 Preliminary ChecksThis 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.Before installing the Liebert NXL Power-Tie, make these preliminary checks:

• Examine the Liebert NXL Power-Tie for transit damage, both internally and externally. Report any damage to the shipper immediately.

• Verify that the correct equipment is being installed. The Liebert NXL Power-Tie cabinet has an identification tag on the interior doors listing 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.

Note 1


2.1.1 Programmable Relay BoardThe Programmable Relay Board (PRB) provides a means to trigger an external device when an event occurs in the Liebert NXL. Each PRB has eight channels. Each channel has Form-C dry contacts rated at 1A @ 30VDC or 125VAC @ 0.45A.Any alarm/event can be programmed to any channel or channels. Up to four (4) events can be programmed to a relay. If multiple events are grouped to one relay, any of the events becoming active will activate the channel. The same alarm/event can be programmed to more than one channel. Up to two Programmable Relay Boards can be installed in the Liebert NXL for a total of 16 channels. Programming is performed through the HMI touchscreen display.
