Vertiv Liebert EXL S1 UPS BACnet points list

Updated 6 November 2026

Short answer

The Liebert EXL S1 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 254 BACnet objects for the Vertiv Liebert EXL S1 UPS — 1 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 EXL S1 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 EXL S1 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 EXL S1 UPS

How many BACnet points does the Vertiv Liebert EXL S1 UPS have?

This list has 254 BACnet objects: 161 analog values, 65 binary values, 28 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Vertiv Liebert EXL S1 UPS BACnet points are writable?

1 of the 254 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 EXL S1 UPS BACnet documentation?

What are the minimum BACnet points to integrate the Vertiv Liebert EXL S1 UPS?

Start with MV 14 4123_1 (Normal, warning or alarm state); MV 16 5971_1 (UPS operating state); MV 13 4872_1 (Load on inverter, bypass or battery); AV 145 4150_1 (Estimated battery runtime, min); AV 50 4096_1 (Input voltage, V); AV 247 4385_1 (Output voltage, V); AV 253 4204_1 (Output current, A); BV 40 4168_1 (Load is on battery); BV 52 4300_1 (Internal communication lost).

How do I check these points on the real Liebert EXL S1 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.
