APC by Schneider Electric LIBSMG95RACKUL Li-Ion 9540A Empty Rack Frame
Overview
The LIBSMG95RACKUL is APC by Schneider Electric's empty rack frame designed to house Li-ion battery modules in large-scale 9540A battery systems. Standing 80.91 inches tall and built around Samsung lithium-ion cells, this frame is the structural and electrical foundation for high-capacity energy storage deployments — data centers, critical infrastructure sites, and large UPS installations where battery density, serviceability, and runtime scalability all matter. Before specifying this unit, understand the key detail: it ships with zero battery slots populated and zero battery modules included. You are purchasing the frame itself, not a functioning battery assembly. Battery modules are ordered separately and installed on-site.
For facilities engineers and power system integrators evaluating APC by Schneider Electric power infrastructure, the LIBSMG95RACKUL fits into the modular Li-ion battery architecture that allows capacity to be scaled by populating the frame incrementally rather than replacing entire battery strings. That modularity has real value in phased build-outs and capacity expansions without full system downtime.
Key Features
- Samsung Li-Ion Cell Platform: The battery modules that populate this frame use Samsung lithium-ion chemistry — a meaningful spec for anyone who has dealt with warranty disputes or premature cell degradation on generic Li-ion UPS batteries. Samsung's manufacturing consistency translates to more predictable cycle life and tighter cell-to-cell variance across the string.
- UL Listed Certification: The LIBSMG95RACKUL carries UL Listing, which matters when you're submitting electrical plans for permit review or dealing with an AHJ (Authority Having Jurisdiction) that requires listed equipment for occupied buildings. This is not a self-certification — it's a third-party tested listing.
- Large-Format Physical Footprint — Plan Your Floor Space: At 80.91 in H × 25.59 in W × 23.58 in D (205.5 cm × 65 cm × 59.9 cm) and 418.88 lb (190 kg) unloaded, this frame demands dedicated floor space and structural floor load planning before it arrives. Adding populated battery modules will increase the loaded weight substantially beyond the 418.88 lb unloaded figure — coordinate with your structural engineer.
- Not Rack-Mountable — Floor-Standing Only: The mounting mode is explicitly not rack-mountable. This is a floor-standing cabinet-style frame, not a standard 19-inch or 23-inch rack unit. Data center managers expecting to slide this into an existing server rack cabinet need to re-evaluate their physical layout before ordering.
- Controlled Operating Environment Required: Rated for 64–82 °F (18–28 °C) ambient operation and 32–104 °F (0–40 °C) for storage. The operating window is notably narrow at 18°C — this is not a battery frame for unconditioned mechanical rooms or outdoor enclosures. It belongs in a temperature-controlled data center or battery room with active HVAC. Exceed this range and you risk accelerated cell degradation and voided warranty claims.
- Storage Humidity Constraint: Maximum 60% relative humidity during storage. If this frame sits in a warehouse or staging area for any period before installation, log the environmental conditions. High-humidity staging environments can introduce moisture ingress issues before the unit ever reaches its final location.
- 3-Year Repair or Replace Warranty: APC covers this unit for 3 years under a repair-or-replace warranty — not a simple return-to-depot arrangement. For mission-critical power infrastructure, that distinction matters: repair-or-replace means APC bears the cost of restoring function, not just issuing a credit.
Integration and Compatibility
The LIBSMG95RACKUL is designed for integration within APC's UPS and battery system ecosystem, specifically the 9540A Li-ion battery platform. Integrators specifying this frame should confirm compatible battery module part numbers with APC's configuration tools before purchase — the frame's value is entirely dependent on which modules it is designed to accept. This is not a universal battery cabinet; it is purpose-built for a specific APC battery module family.
Given its floor-standing profile and large physical envelope, installation planning should include cable management routing to the associated UPS, inter-frame bus connections if multiple frames are deployed in parallel, and access clearances on all four sides for module swap procedures during maintenance windows. Review APC's installation and planning guides for the 9540A battery system before committing to a floor layout — retrofitting inadequate clearances after installation is expensive.
For facilities running power distribution and UPS infrastructure at scale, the modular design of this platform allows battery capacity additions without replacing the entire string, a meaningful operational advantage over traditional VRLA battery cabinet approaches.
Frequently Asked Questions
Q: Does the LIBSMG95RACKUL include any battery modules?
A: No. The LIBSMG95RACKUL ships as an empty rack frame with zero battery slots populated and zero battery modules included. Battery modules must be ordered separately and are installed into the frame on-site.
Q: What is the warranty on the LIBSMG95RACKUL?
A: APC covers the LIBSMG95RACKUL with a 3-year repair or replace warranty.
Q: Can the LIBSMG95RACKUL be mounted in a standard server rack?
A: No. The mounting mode for this unit is explicitly not rack-mountable. It is a floor-standing frame at 80.91 inches tall and must be planned for as a standalone floor installation, not a rack-mount component.
Q: What battery chemistry does this frame support?
A: The LIBSMG95RACKUL is designed for Li-ion (Lithium Ion) battery modules using Samsung cells. It is not designed for VRLA or other legacy battery chemistries.
Q: What are the operating temperature requirements for the LIBSMG95RACKUL?
A: The frame is rated for 64–82 °F (18–28 °C) ambient operating temperature. This is a controlled-environment unit — unconditioned rooms, outdoor enclosures, or spaces outside this range are not suitable installations.
Q: What does the LIBSMG95RACKUL weigh, and do I need structural floor load planning?
A: The frame weighs 418.88 lb (190 kg) unloaded. When battery modules are installed, total loaded weight will be substantially higher. Structural floor load assessment is required before installation — consult your structural engineer with the full populated weight spec from APC's configuration documentation.
The LIBSMG95RACKUL is one of those line items that looks straightforward until you receive it on a job site — it is an empty frame, full stop. What it offers is the physical and electrical infrastructure to build out a high-capacity Li-ion battery bank using Samsung cells in a modular fashion, but the 418.88 lb unloaded weight and 80.91-inch floor-to-ceiling height mean your site prep has to happen well before this unit shows up on a pallet.
Technical Highlights:
- Samsung Li-Ion Chemistry: Samsung cell manufacturing consistency reduces inter-cell variance across the string — a practical advantage for long-duration discharge curves and cycle life predictability in critical UPS applications.
- UL Listed: Third-party UL Listing is the relevant compliance credential for permit submissions and AHJ sign-off on occupied commercial and data center builds. Self-certified units don't satisfy this requirement.
- 3-Year Repair or Replace Warranty: APC's repair-or-replace terms mean the manufacturer bears the restoration cost — not just a credit — for a full 3-year window, which matters when the battery system is load-bearing for a critical facility.
Deployment Considerations:
- The 64–82 °F (18–28 °C) operating temperature window is tight. Budget for active HVAC in the battery room — passive or spot-cooling approaches frequently fail to hold this range under full load in summer peak conditions.
- Do not assume this frame accepts arbitrary APC battery modules. Confirm the exact compatible module part numbers through APC's 9540A configuration documentation before placing the battery module order — mismatched modules are a costly return freight problem on 190 kg freight.
This frame is the right specification for a phased large-UPS build-out in a controlled data center or dedicated battery room where the team wants to add Li-ion capacity incrementally without replacing a full battery string. It is the wrong call for any deployment that cannot guarantee the 18–28 °C ambient operating window year-round.
