IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation of your Liebert NX™ UPS and batteries. Read this manual thoroughly, paying special attention to the sections that apply to your installation, before working with the UPS. Retain this manual for use by installing personnel. WARNING ! Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. The UPS module weight r

CAUTION ! This equipment is fitted with RFI suppression filters. Ground leakage current exceeds 3.5 mA and is less than 1000 mA. Transient and steady-state ground leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous residual current circuit breakers (RCCBs) or residual current devices (RCDs). RCCBs must be selected sensitive to DC unidirectional pulses (Class A) and insensitive to transient current pulses. Note also that the

Installation 1.0 INSTALLATION 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

Installation 1.2.1 Storing for Delayed Installation If the equipment will not be installed immediately, it must be stored indoors where the humidity is no higher than 90% and the temperature is no higher than 104°F (40°C). The storage area must protect the NX from excessive moisture (see 6.2 - UPS Environmental). CAUTION ! If the UPS must remain disconnected from power for more than six (6) months, the battery must be recharged before use. To charge the batteries, the unit must be connected t

Installation 1.4.3 Special Considerations for 1+N Systems 1. Consider the grounding configuration of your system before finalizing module placement. For optimal ground performance, the NX modules should be close together. 2. For optimal load-sharing performance, the UPS output cables should be approximately the same length, plus or minus 20 percent. 3. Position modules in such a way as to minimize the length of power cables and control wiring between UPS modules and the paralleling cabinet. 1

Installation 1.6.1 Clearances There are no ventilation grilles on the sides or rear of the UPS. The sides must be accessible during installation. After installation, the unit may be placed with the rear against a wall and optional cabi- nets on either side. To enable routine tightening of power terminations within the UPS, make sure there is sufficient clearance in front of the NX to permit free passage of personnel with the door fully opened. Leave a minimum of 2 ft. (610mm) between the top o

Installation 1.6.4 Optional Cabinets If your NX installation includes a Maintenance Bypass Cabinet, the NX must be positioned to allow the Maintenance Bypass Cabinet to be bolted to left side of the NX (see Figure 1). Cables from the Maintenance Bypass Cabinet must be brought through the bottom side of the NX for connection. The Maintenance Bypass Cabinet must be cabled and bolted to the NX before the UPS and bypass cabinet are moved into their final position. Connect the input wiring to the

Electrical Connections 2.0 ELECTRICAL CONNECTIONS The UPS requires both power and control cabling once it has been mechanically installed. All control cables must run separate from power cables in metal conduits or metal ducts that are electrically bonded to the metalwork of the cabinets to which they are connected. WARNING ! Before connecting input power to the NX, ensure that you are aware of the location and operation of the overcurrent protection devices that connect the UPS input/bypass

Electrical Connections 2.1.2 UPS Input Configuration Figure 2 illustrates the NX in a split bypass (dual-input) configuration. In this configuration the Static Bypass and the Maintenance Bypass lines are supplied from a separate feed from the Main input. Both sources must be protected externally with properly sized protective devices. By default, the unit ships with internal links installed between the Bypass input and Main input (Single Input configuration). To wire the unit as a dual input

Electrical Connections 2.1.4 Cable Connections The rectifier input, bypass and output are easily accessible from the left side of the unit for installa- tion. All require lug type terminations. They are connected to busbars on the left side of the NX and below the switch, as shown in Figure 3. These busbars are accessible when the left side panel is removed. Busbars to connect external batteries are accessible from the front of the UPS. NOTE External battery connection access requires removal

Electrical Connections 2.1.5 Safety Ground The safety ground busbar is located below the neutral input and output busbars as shown in Figure 5 below. The safety ground cable must be connected to the ground busbar and bonded to each cabinet in the system. All cabinets and cable conduit should be grounded in accordance with local regulations. WARNING ! Failure to follow proper grounding procedures can result in electric shock hazard to personnel or the risk of fire, should a ground fault occur.

Electrical Connections 2.1.7 Cabling Procedure CAUTION ! The operations described in this section must be performed by authorized electricians or qualified technical personnel. If you have any difficulties, contact your local Liebert representative or Liebert Global Services. NOTE Hydraulic pressure pliers, combinative tools and piston ring pliers should be used to connect AC wiring. Once the equipment has been positioned and secured for operation, and the battery and ground col- lars have be

Electrical Connections Internal UPS Battery Connections The UPS internal batteries will be connected at the factory, EXCEPT the Anderson connections between the shelves and to the fuses. WARNING ! The DC bus is live when this internal battery connection is made. This connection is to be performed ONLY by Liebert Global Services at startup. Observe the battery cable polarity. Be sure that the battery connector is made with the cor- rect polarity. 11. Refit all protective covers removed for cabl
