Vertiv Liebert GXT3 / GXT4 UPS BACnet points list

Updated 6 November 2026

Short answer

The Liebert GXT3 / GXT4 UPS reports to a BMS through a Liebert IntelliSlot card (BACnet IP or BACnet MS/TP). Analog Values carry input, bypass, output and battery measurements, Binary Values carry UPS events, and Multi-state Values carry system status, output source and settings. Objects are created when the card discovers the UPS.

This page lists 113 BACnet objects for the Vertiv Liebert GXT3 / GXT4 UPS — 14 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Vertiv’s own free documentation, linked below.

BMS integration notes: Vertiv Liebert GXT3 / GXT4 UPS

Integration in brief

Fit a Liebert IntelliSlot BACnet card (IS-UNITY-DP for BACnet IP or MS/TP), give it a unique device instance and let it discover the equipment; the objects are then created automatically. Map the status, main measurements and event objects for monitoring.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Liebert GXT3 / GXT4 UPS and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Vertiv Liebert GXT3 / GXT4 UPS

How many BACnet points does the Vertiv Liebert GXT3 / GXT4 UPS have?

This list has 113 BACnet objects: 63 analog values, 24 binary values, 26 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Vertiv Liebert GXT3 / GXT4 UPS BACnet points are writable?

14 of the 113 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.

Where is the official Vertiv Liebert GXT3 / GXT4 UPS BACnet documentation?

The source is Liebert IntelliSlot Modbus/BACnet Reference Guide (Modbus RTU and TCP, BACnet MSTP and IP) (SL-28170), revision 2024-04 (Rev 29), published free by Vertiv at https://www.vertiv.com/49fb41/globalassets/shared/liebert-intellislot-modbus-rtu-reference-guide-SL-28170_0.pdf.

What are the minimum BACnet points to integrate the Vertiv Liebert GXT3 / GXT4 UPS?

Start with MV 76 4123_1 (Normal, warning or alarm state); MV 30 4872_1 (Load on inverter, bypass or battery); AV 41 4150_1 (Estimated battery runtime, min); AV 71 4208_1 (Output power, W); AV 1 4096_1 (Input voltage, V); AV 61 4385_1 (Output voltage, V); AV 63 4204_1 (Output current, A).

How do I check these points on the real Liebert GXT3 / GXT4 UPS?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
