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. -
Page 13: Clearances
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. -
Page 14: Optional Cabinets
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. -
Page 15: E Lectrical C Onnections
LECTRICAL ONNECTIONS 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 supply to... -
Page 16: Ups Input Configuration
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). -
Page 17: Cable 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. -

Page 25: B Attery I Nstallation
ATTERY NSTALLATION Introduction Liebert recommends that the batteries in external cabinets match the internal batteries in the NX in manufacturer and type. If using multiple sets of batteries connected in parallel to provide the required battery backup run times, fit each set with an isolating device to permit working on one of the battery sets while leaving the others in service and providing backup protection. -
Page 26: External Battery Cabinet Installation
External Battery Cabinet Installation 3.4.1 Matching Battery Cabinets Two sizes of optional battery cabinets are available. Refer to Figures 13 and 14. The same model bat- tery cabinet may be installed in parallel in multiple cabinet strings for additional capacity. Battery run time depends on the cabinet model, the number of cabinets and the load on the UPS. -

Connect the system outnput cables between the Maintenance Bypass Cabinet 'UPS Output' Busbars (A-B-C N terminals) and UPS output busbars (A-B-C N terminals) and tighten the connections to 44 lb-in. -
Page 35: Bolting Cabinets Together
Bolting Cabinets Together NOTE UPS wiring must be completed before the cabinets are bolted together. 1. Line up cabinets so that mounting holes are aligned. 2. Using supplied hardware, bolt the cabinets together. The bolts may be inserted from either the UPS side or from the MBS side, whichever is more convenient. -
Page 36: Options
PTIONS Load Bus Synchronization The Load Bus Synchronizer (LBS) keeps the output of two independent UPS systems or parallel UPS systems in synchronization even when the systems are operating in different modes and even when either or both systems are operating on batteries. When the LBS is used, one UPS system is desig- nated as master, the other as slave. -
Page 37: Configuring Parallel System Operation
The 1+N system is used to: • Increase the reliability of the system to ensure adequate power supply to the critical load con- nected. • Increase serviceability and allow the execution of maintenance operations and reparations with- out affecting the ordinary operating conditions of the system (depending on the redundancy level). -
Page 38: Operating Principles
The sequence to transfer to maintenance bypass mode is the same as for transferring a single- module system. The maintenance bypass switches should be switched on as synchronously as pos- sible. Thus the system can be repaired without interrupting the power supply to critical load. Installing Parallel System The basic installation procedure of parallel system is the same as that of single module system. -
Page 39: Power Cables
5.3.5 Power Cables Wiring of power cables is similar to that of single module system (See 2.1 - Power Cabling). The bypass sources of all modules should be the same, and the outputs should be connected altogether cor- rectly. Power cables will be supplied by customer. Power cables to the UPS’s of the 1+N paralleling cabinet must be routed through either the top or bottom entry access of the UPS. -
