Vertiv Liebert EXM2 dossier: 100-250 kVA/kW, VFI-SS-111 declared, 99.2% eco efficiency, EMEA and APAC only, and what a US buyer should look at instead.
Liebert EXM2 is Vertiv's monolithic mid-frame UPS at 100 to 250 kVA/kW with unity output power factor, reaching up to 97% in double conversion, 98.8% in Dynamic Online and 99.2% in eco mode. It is declared to IEC 62040-3 classification VFI-SS-111 and is lithium-ion ready, with Vertiv rating VRLA at three to five years against lithium-ion at ten to fifteen. Vertiv's own descriptor calls it a monolithic uninterruptible power supply for the rising need of highly reliable and efficient UPS in next-generation mid-size critical applications.
Region restriction is the fact that governs any listing. The EXM2 appears on Vertiv's EMEA three-phase lineup and on Asia and India locales, and does not appear on the US lineup, which carries Liebert EXM instead. The EXM2 page is not available on Vertiv's Canadian site. On the EMEA lineup the anchor text Liebert EXM UPS points at the EXM2 URL, so in EMEA the EXM2 has replaced the EXM while in North America the EXM remains current.
No used or refurbished EXM2 carries a published price, and none should be expected in the United States. A US-market secondary EXM2 listing should be treated as a grey import or a mislabeled Liebert EXM. The Americas equivalent a US buyer actually searches for is the Liebert EXM at 10 to 200 kVA/kW on 208 V and 30 to 250 kVA/kW on 480 V.
Why it matters
The EXM2 is one of the few UPS platforms in this band that publishes its IEC 62040-3 class outright. That string is a durable, verifiable specification that survives resale, unlike efficiency figures that depend on load point or battery claims that depend on what is in the cabinet. Most units in this band publish no class code at all, so ask for it before comparing two offers.
Who buys it
EMEA and APAC data center and enterprise buyers in the 100 to 250 kVA band who want a monolithic machine with a declared VFI-SS-111 class and a lithium-ready battery path. North American buyers should be routed to the Liebert EXM, which is the current product in that market and carries a configure-to-delivery option of four days on the 10 to 40 kVA band.
Role in the data center
Mid-frame primary UPS for EMEA and APAC data halls and enterprise facilities in the 100 to 250 kVA band, sitting on the critical bus with an external VRLA or lithium battery plant. Vertiv declares it to IEC 62040-3 class VFI-SS-111, so it holds output voltage and frequency independent of the mains across all load conditions.

Major variations
Brochure ratings run 100 to 250 kVA/kW at unity output power factor with VRLA or lithium-ion battery configurations. Vertiv HPL is named separately from generic lithium-ion in Vertiv's own battery-compatibility lists, so the two should not be treated as synonyms when reading a specification. The Americas equivalent is the Liebert EXM at 10-200 kVA/kW on 208 V and 30-250 kVA/kW on 480 V, a different catalogue entry with its own rating table and a configure-to-delivery option of four days on the 10-40 kVA band in the USA. In EMEA the EXM2 has replaced the EXM; in North America the EXM remains current.
Configurations and options
The options that can be verified from public documentation are the rating, 100 to 250 kVA and kW at unity output power factor, and the battery configuration, VRLA or lithium-ion, with Vertiv rating VRLA at three to five years against lithium at ten to fifteen. One naming trap belongs on any order: Vertiv lists Vertiv HPL separately from generic lithium-ion in its own battery compatibility statements, so the two are not interchangeable terms on a specification. Vertiv restricts the EXM2 product pages in its EMEA, Asia and India locales to account holders, so no public option list, footprint table or lead time is published as of September 2026 and the configurable items beyond those have to come from a partner quotation.
Compatibility and dependencies
The EXM2 is monolithic rather than modular, so capacity is fixed at the frame and power-stage service means a transfer to maintenance bypass rather than a module swap; budget an external maintenance bypass accordingly. Vertiv declares the unit to IEC 62040-3 class VFI-SS-111, which is the classification most data center specifications call for and which stays verifiable through a resale. Battery plant is external, and Vertiv's lithium-ion cabinets are UL 1973 listed, UL 9540A tested and UL 9540 qualified. Vertiv publishes no input or output voltage table, no footprint and no parallel capability for the EXM2 on any page reachable without a partner account as of September 2026, so voltage, frequency and listing have to be read from the machine's own nameplate before it is matched to a North American board. The model a US buyer specifies instead is the Liebert EXM at 208 V or 480 V.
Pricing and availability
Trend: rising Lead time, used or refurbished: No used or refurbished unit listed as of August 2026. Warranty, used: 1-year typical from refurbishment dealers.
Lifecycle and maintenance
Static UPS cabinets serve roughly 15 years, the figure Mitsubishi publishes alongside a lifecycle-parts-or-replace decision at 10-12 years. The wear items are documented: Eaton rates DC bus capacitors at 7 years of continuous duty and up to 10 in favourable conditions, Riello puts capacitor service life at 10 years with replacement recommended between years 4 and 8, and Vertiv field data gives 6 years for capacitors and 5-6 years or 40,000-50,000 hours for cooling fans. Batteries turn over far faster, at 3-5 years for sealed VRLA and 12-15 for flooded cells, and spent lead-acid leaves as regulated waste through compliant recycling rather than resale. Service life extension programs rebuild the power train inside the original shell, which is why cabinets routinely outlive their electronics.
Thermal and emissions profile
UPS systems produce no combustion emissions, so the regulatory weight sits on the battery. The 2026 edition of NFPA 855 broadens detection to smoke, thermal-imaging and radiant-energy systems, mandates large-scale fire testing alongside UL 9540A to prove no propagation between adjacent units, and adds a staging exception for batteries held at or below 50% state of charge that matters directly to anyone moving lithium cabinets through a secondary market. Uptime Institute's 2026 outage analysis names lithium-ion batteries in UPS systems as a clear contributor to a gradual rise in major data center fires. Confirm UL 1973, UL 9540A and UL 9540 status on any lithium cabinet, then confirm what the authority having jurisdiction requires to requalify the room.
Common failure points
- Battery strings — VRLA capacity fades below 80% of nameplate and takes the ride-through with it
- DC bus capacitors — Silent open-circuit loss, or a short that pops and sprays electrolyte across adjacent boards
- Cooling fans — Overheating transfers the load to bypass and leaves it unprotected
- Air filters and dust — Restricted airflow raises internal temperature and shortens capacitor life
- Static bypass switch — Failure to transfer strands the load during maintenance or overload
- Controls obsolescence — Discontinued display and logic boards turn a routine repair into a scavenger hunt
Inspection checklist
Battery age: sealed VRLA turns over at 3-5 years per Eaton lifecycle guidance; assume a full string past that. Battery capacity: reject any string below 80% of nameplate capacity under IEEE 1188 practice. Battery impedance: treat ohmic readings more than 20% above the commissioning baseline as an investigation trigger under IEEE 1188 field practice, then confirm against the battery manufacturer limit for the chemistry before condemning a cell. Float voltage: verify 2.23-2.27 VPC at 25 degrees C; float current above 3x steady state flags thermal runaway. Intercell connectors: thermal image every joint; a delta above 5 degrees C against neighbors triggers a capacity test. DC bus capacitors: Eaton rates 7 years of continuous duty (10 optimal); Vertiv field data gives 6 years at 45,000-50,000 h. Cooling fans: Vertiv field data gives 5-6 years or 40,000-50,000 hours; listen for bearing noise at the intake. Air filters: pull every filter; a clogged element is the best single proxy for a cabinet that ran above 25 degrees C.
Procurement channels
New units come through Vertiv's EMEA and APAC channel; Vertiv restricts the product pages to account holders; the ratings are published in its brochures. The Americas channel sells the Liebert EXM instead, which Gruber Power Services stocks new at 250 kVA without a public price.
Regional notes
EMEA and APAC only, with catalogue entries in the EMEA, Asia and India locales. The EXM2 page is not available on Vertiv's Canadian site, and the US lineup carries Liebert EXM instead. A US secondary listing for an EXM2 should be treated as a grey import or a mislabeled EXM.
