Vertiv Liebert EPM UPS BACnet points list

Updated 6 November 2026

Short answer

The Liebert EPM 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 146 BACnet objects for the Vertiv Liebert EPM 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 EPM 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 EPM 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 EPM UPS

How many BACnet points does the Vertiv Liebert EPM UPS have?

This list has 146 BACnet objects: 65 analog values, 68 binary values, 13 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Vertiv Liebert EPM UPS BACnet points are writable?

1 of the 146 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 EPM 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 EPM UPS?

Start with MV 15 4123_1 (Normal, warning or alarm state); MV 14 4872_1 (Load on inverter, bypass or battery); AV 41 4150_1 (Estimated battery runtime, min); AV 82 4208_1 (Output power, kW); AV 1 4097_1 (Input voltage, V); AV 55 4385_1 (Output voltage, V); AV 58 4204_1 (Output current, A); BV 51 4168_1 (Load is on battery); BV 40 4300_1 (Internal communication lost).

How do I check these points on the real Liebert EPM 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.
