General

Liebert’s Load Bus Sync (LBS) Extender/Adapter for Dual Bus UPS is designed to extend the LBS
function, up to 150m (492 ft.) between Liebert NX
power system (UPS) modules of a dual bus system (DBS). The adapter also enables a Liebert NX UPS
or a Liebert Hipulse U to synchronize with other UPS models.

2.1 UPS Connections: Liebert NX and Liebert Hipulse U

The procedure below permits using a Liebert LBS Extender/Adapter to connect UPSs in the following
configurations:

• Liebert NX to Liebert NX

• Liebert NX to Liebert Hipulse U

• Liebert Hipulse U to Liebert Hipulse U

WARNING

!

Installation by qualified electrical personnel only—hazardous voltage may be present at the
UPS output connectors.

1. Connect the power cables of the adapter to the Phase A, Neutral and Ground output of each UPS.

2. Connect the LBS cable to COM1 of each LBS Signal Adapter.

3. Connect the other end of each LBS cable to X4 on the parallel board (UHW241M3) in the Liebert
NX UPS or the Liebert Hipulse U.

4. Connect the communication cable (up to 492ft. [150m]) to the COM2 interface of each LBS Signal
Adapter.

5. The switch of both LBS signal adapters should be in the right position (see Figure 4).

4. Connect the communication cable (up to 492ft. [150m]) to the COM2 interface of each LBS Signal
Adapter.

5. The switches of LBS signal adapters connected to the Liebert NX or the Liebert Hipulse U should
be in the right position and the switches of DBS signal adapters connected to the other model of
UPS (neither Liebert NX nor Liebert HipulseU) should be in the left position (see Figure 5).
