Product Overview
VERTIV EBU01 Replacement Upgrade Solution for EBU Series: Seamless Transition from Legacy UPS Battery Systems
When your existing UPS infrastructure relies on aging or discontinued battery extension configurations, the VERTIV EBU01 Battery Extension Unit (SKU: EBU01) delivers a direct, field-proven upgrade path. Designed for industrial control environments where power continuity is non-negotiable, the EBU01 integrates into existing VERTIV EBU Series UPS architectures with minimal rewiring, no firmware conflicts, and no rack modification. Whether you are retiring an end-of-life Liebert GXT series battery cabinet, replacing a failed VERTIV SBM (Static Bypass Module) auxiliary battery pack, or consolidating redundant power strings in a DCS or PLC control room, the EBU01 provides a structurally and electrically compatible replacement that preserves your existing runtime calculations and load profiles.
Industrial facilities running Siemens S7-300 or S7-400 PLC racks, ABB AC500 controllers, or Rockwell Automation ControlLogix chassis depend on uninterrupted 24 VDC or 48 VDC bus stability. Any gap in UPS battery backup during a module swap can trigger unexpected CPU faults, I/O module resets, or communication dropouts on PROFIBUS DP, Modbus RTU, or EtherNet/IP networks. The EBU01 is engineered to be hot-swappable within the VERTIV EBU Series frame, allowing maintenance teams to replace a degraded battery extension unit without powering down the protected load — a critical advantage in continuous-process industries such as petrochemical, water treatment, and discrete manufacturing.

Seamless Upgrade Solutions
A successful EBU01 migration rarely involves a single component. In practice, field engineers replacing a degraded battery extension unit also audit the surrounding power and control architecture. The VERTIV Liebert GXT4 UPS main unit is the most common host system for EBU01 integration; if the GXT4 is also approaching end-of-service, a parallel replacement plan should be initiated to avoid a second unplanned outage. Alongside the UPS host, the VERTIV Intellislot Unity Card enables SNMP-based remote monitoring of battery health, charge state, and estimated runtime — a capability that legacy RS-485-only configurations cannot provide without a protocol converter.
In control rooms where the EBU01 supports a Schneider Electric Modicon M340 or M580 PLC rack, the associated BMXCPS3020 or BMXCPS4002 power supply modules should be inspected for capacitor aging concurrent with the battery extension replacement. Similarly, facilities running Honeywell Experion PKS DCS nodes or Emerson DeltaV I/O cards on the same UPS string should verify that the VERTIV EBU01’s runtime extension is sufficient for a controlled shutdown sequence of all field devices, including 4–20 mA analog I/O modules, HART multiplexers, and Foundation Fieldbus H1 segment power conditioners.
For installations where the EBU01 feeds power to a control cabinet housing a Mitsubishi MELSEC Q-series or iQ-R series CPU module alongside CC-Link IE Field network master cards, the battery extension runtime must account for the network keepalive timeout parameters configured in GX Works3. Replacing the EBU01 without verifying these timeout values can result in CC-Link IE Field network disconnection events that require a full network re-initialization after power restoration. The VERTIV EBU01 provides sufficient runtime headroom for a graceful shutdown when properly sized against the total VA load of the cabinet.
Additional components commonly sourced alongside the EBU01 include VERTIV DC bus fuse assemblies, replacement battery interconnect cables with pre-crimped ring lugs, and DIN-rail-mounted 24 VDC signal isolators used to decouple the UPS status relay output from the PLC digital input card. These isolators prevent ground loop interference that can cause false low-battery alarms on Siemens ET 200SP distributed I/O or Beckhoff EtherCAT terminal modules connected to the same control network.
Retrofit Guidance FAQ
Q: Can the EBU01 replace my existing battery extension unit without rewiring the DC bus terminals?
A: Yes. The EBU01 uses the same rear-panel Anderson connector and ring-lug terminal layout as the prior-generation VERTIV EBU Series units. No DC bus rewiring is required for a direct 1:1 replacement. Verify torque specifications on terminal connections per VERTIV installation documentation before energizing.
Q: Will my existing SNMP or RS-485 monitoring configuration continue to work after installing the EBU01?
A: The EBU01 is protocol-transparent at the battery extension level. Communication is managed by the Intellislot card installed in the host UPS unit. If your host UPS uses an Intellislot Unity Card or equivalent SNMP adapter, your existing NMS (Network Management System) polling configuration, OID mappings, and trap destinations remain valid without modification.
Q: How much physical space does the EBU01 require, and will it fit in my existing control cabinet?
A: The EBU01 is designed for standard 19-inch rack mounting within the VERTIV EBU Series frame. Tower configurations are also supported. No additional rack units or cabinet depth modification are required beyond the original EBU Series installation footprint.
Q: What programming changes are needed in my PLC or DCS after replacing the EBU01?
A: None, provided the host UPS unit remains unchanged. The EBU01 is transparent to the control system. The UPS presents the same status relay outputs (on-battery, low-battery, fault) to the PLC digital input card regardless of which battery extension unit is installed. If you are also upgrading the host UPS, review the relay output pinout and contact rating to confirm compatibility with your existing DI module wiring.
Q: What is the lead time and shipping arrangement for the EBU01?
A: Stock units ship from Xiamen within 1–3 business days. International shipments are dispatched via DHL Express or FedEx International Priority with full tracking. Customs documentation, including commercial invoice and packing list with HS code, is provided for all cross-border orders.
