5.1Load 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.

The LBS option is typically used with dual-corded equipment or with either the Liebert SmartSwitch or Static Transfer Switch (STS) for single-corded equipment.

5.1.1Performance Requirements

The DBS operates under the following conditions:

•Both master and slave are on inverter

(either system may be on inverter through the rectifier or on inverter through the batteries)

•Master on inverter, and slave on bypass

•Master on bypass, and slave on inverter

•Master and slave on bypass IF the bypass source is the same for both systems

5.1.2DBS Cable and Settings

For NX-to-NX dual bus configuration, only one optional LBS cable is required, the built-in LBS will operate normally without extra LBS control box or interface box. The LBS port is X4 on the parallel board (M3). The parallel board is on the interior of the NX, above and left of the power electronics; see Figure 30.

An optional, 9-pin LBS cable is used to connect two UPS systems through each system’s DB9 port on its parallel board. For two parallel systems, the LBS cable can be mounted between any two units belonging to different parallel systems. For information about the LBS kit or to order the optional equipment, see your local Liebert representative.

The LBS cable is connected as illustrated in Figure 21.
