Vertiv ITA2-08KMBCSL1 8kVA UPS Cord-and-Plug Cable Kit
Overview
The Vertiv ITA2-08KMBCSL1 is a factory-made cable kit that converts the standard hard-wired connections on a Liebert ITA2 8kVA UPS to a cord-and-plug configuration — making installation and future servicing significantly more practical in rack-dense data centers and critical power environments. Rather than committing an 8kVA UPS to a fixed hard-wired circuit that requires an electrician to disconnect for any maintenance event, the ITA2-08KMBCSL1 lets you break the circuit at the plug, reducing both labor cost and downtime risk during planned maintenance windows.
This kit ships as two cords: a 10 ft (3m) main input cord terminated with an L21-30P plug, and a 1 ft (305mm) main output cord terminated with an L21-30R receptacle. The L21-30 twist-lock connector family is a NEMA standard rated for three-phase 30A service, which aligns with the power delivery requirements of an 8kVA UPS running at full load. The short 1 ft output cord is intentionally sized to minimize voltage drop between the UPS output and the connected load distribution — not a general-purpose extension.

Key Features
- 10 ft Input Cord with L21-30P Plug: A 10-foot run gives you enough slack to reach a dedicated three-phase 30A circuit breaker panel or PDU without excessive coiling. L21-30P is a twist-lock connector — it won't vibrate loose in a raised-floor environment the way straight-blade plugs can over time.
- 1 ft Output Cord with L21-30R Receptacle: The 1 ft output cord exists to terminate the UPS output side with a twist-lock receptacle rather than a hard-wired lug. Keep it short — this cord connects to a downstream distribution device (PDU, MBC), not to end devices directly.
- Cord-and-Plug Conversion: Converting from hard-wired to cord-and-plug means future UPS swaps don't require an electrician on-site to disconnect and reconnect wiring. For managed service providers and facilities teams handling multiple UPS refresh cycles, that's a measurable reduction in planned maintenance cost.
- Dual-Use Design — Standalone or MBC: The ITA2-08KMBCSL1 works in two configurations: as the sole input/output cord set for a stand-alone 8kVA ITA2 UPS without an external MBC, or as the main input/output connection for the 8kVA-rated rack-mount MBC in a single-input system. One SKU covers both deployment patterns — useful when ordering for mixed rack configurations.
- L21-30 Twist-Lock Standard: NEMA L21-30 is a widely supported three-phase connector standard found on compatible PDUs, transfer switches, and power panels in commercial and enterprise environments. Matching plug and receptacle types on both ends of this kit means no adapter required at either connection point.
- Weight and Form Factor (11.06 lbs): At 11 lbs, this is a substantial cable assembly — not a lightweight patch cord. Plan for proper cable management support in the rack to avoid strain on UPS input terminals, particularly on the L21-30P plug end where the 10 ft cord weight could stress the connector body if left unsupported.
Integration and Compatibility
The ITA2-08KMBCSL1 is designed specifically for use with the Liebert ITA2 8kVA UPS platform. It is not a universal cord kit — the 8kVA rating and L21-30 connector standard are matched to the ITA2's power architecture. Verify your ITA2 variant is 8kVA before ordering; higher-kVA ITA2 models require different cord assemblies with appropriately rated connectors and conductors. For multi-module bypass cabinet (MBC) deployments with more than one input, a different cord kit will be required — this kit supports single-input configurations only.
If you're building out a full rack power chain, pair this cord kit with a compatible rack power distribution unit on the output side, and review your power protection architecture to ensure the L21-30 circuit matches your facility's upstream panel configuration.

Frequently Asked Questions
Q: Which Liebert ITA2 models is the ITA2-08KMBCSL1 compatible with?
A: The ITA2-08KMBCSL1 is rated for use with the Liebert ITA2 8kVA UPS. It supports both a stand-alone 8kVA ITA2 (no external MBC) and the main input/output of an 8kVA rack-mount MBC in a single-input configuration. It is not intended for ITA2 models at other kVA ratings.
Q: What connector type does this kit use?
A: Both cords use the NEMA L21-30 twist-lock standard. The input cord terminates in an L21-30P plug; the output cord terminates in an L21-30R receptacle. L21-30 is a three-phase 30A connector — confirm your facility circuit matches before ordering.
Q: Can this cord kit be used with a multi-input MBC configuration?
A: No. The ITA2-08KMBCSL1 is designed for single-input systems only. Multi-input MBC deployments require a different cord assembly.
Q: What is the length of each cord in this kit?
A: The input cord is 10 ft (3m) long. The output cord is 1 ft (305mm) long. The short output cord is intentional — it terminates the UPS output with an L21-30R receptacle for connection to a downstream PDU or distribution device, not for direct device connections.
Q: Why convert from hard-wired to cord-and-plug on a UPS this size?
A: Hard-wired UPS installations require a licensed electrician to disconnect power before any maintenance or swap. Converting to cord-and-plug with the ITA2-08KMBCSL1 means you can disconnect and reconnect the UPS during a maintenance window without an electrician on-site, reducing planned downtime and service cost over the life of the equipment.
Q: How much does the ITA2-08KMBCSL1 weigh?
A: The cable kit weighs 11.06 lbs. Use proper cable management supports in the rack — unsupported weight on a 10 ft cord can stress the L21-30P plug body and the UPS input terminal over time.
The ITA2-08KMBCSL1 is a purpose-built cord kit, not a generic power cable — and that distinction matters when you're speccing out an 8kVA Liebert ITA2 installation. The L21-30P/R twist-lock connectors are load-rated for the three-phase 30A service this UPS class draws, and the 10 ft input cord gives you a workable reach without forcing a dedicated whip extension between the panel and the UPS. I've seen enough hard-wired 8kVA installs go sideways during a UPS swap to appreciate what cord-and-plug conversion actually buys you operationally.
Technical Highlights:
- 10 ft Input Cord: Provides enough reach for most raised-floor panel-to-rack runs without requiring an additional cord extension, while the L21-30P twist-lock eliminates the vibration-loosening risk common with straight-blade connectors in active equipment rooms.
- 1 ft Output Cord: Intentionally short at 305mm — this is a termination cord, not a run cord. It converts the UPS output lug to an L21-30R receptacle for a clean handoff to a downstream PDU, keeping the output connection as short as possible to minimize voltage drop under load.
- Dual Deployment Mode: The ITA2-08KMBCSL1 covers both stand-alone 8kVA UPS installs and single-input rack-mount MBC configurations — one SKU, two valid use cases, which simplifies procurement when you're stocking for mixed-format ITA2 deployments.
Deployment Considerations:
- At 11.06 lbs, this assembly needs cable management support — run the 10 ft input cord through a horizontal manager before it reaches the L21-30P plug. An unsupported 10 ft cord hanging off a UPS input terminal will fatigue the connector body over repeated maintenance cycles.
- Single-input only: if your MBC configuration has multiple inputs, this kit does not apply. Verify the input count on your MBC spec sheet before ordering to avoid a mis-ship.
The ITA2-08KMBCSL1 is the right call for any data center or colocation environment running Liebert ITA2 8kVA UPS units where the facilities team wants to eliminate the electrician requirement from planned maintenance events — particularly colocation providers managing high-density racks with frequent UPS refresh cycles.
