Liebert NX or Liebert Hipulse U to Other UPS Models

The procedure below permits using a Liebert LBS Extender/Adapter to connect a Liebert NX or Lie-
bert Hipulse U UPS to other UPS models.
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 the LBS Signal Adapter connected to the Liebert NX or the
Liebert Hipulse U.
3. Connect the other end of the LBS cable to X4 on the parallel board (UHW241M3) in the
Liebert NX or Liebert Hipulse U.
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).
