APC Smart-UPS On-Line, 3kVA Tower UPS, 120V — 8x 5-20R + 1x L5-30R Outlets, SmartSlot, Extended Runtime, W/O Rail Kit

This APC Smart-UPS On-Line is built for IT professionals and network administrators who demand relentless uptime and clean, reliable power for critical electronics. With a pure sine wave output and advanced double-conversion technology, this 3 kVA tower UPS protects servers, storage devices, networking gear, and communications equipment from power disturbances, voltage sags, and outages. Designed to deliver consistent performance in demanding environments, it combines a compact tower footprint with a robust set of outlets, flexible expansion options, and SmartSlot compatibility to adapt to evolving IT ecosystems. Ideal for small data centers, server rooms, and network closets, it offers extended runtime when paired with external battery modules, while remaining easy to install and manage without a rail kit included.

• Uncompromising power quality: Pure sine wave output with online, double-conversion topology ensures clean, continuous power to connected equipment even during severe utility irregularities, providing protection for mission-critical devices and preventing data loss.
• Flexible outlet configuration: Eight NEMA 5-20R outlets plus one heavy-duty NEMA L5-30R receptacle offer versatile hard-wiring and surge-protected power for a mix of servers, switches, storage, and networking gear from a single UPS. The L5-30R outlet supports higher-current devices while standard 5-20R outlets handle a broad range of equipment.
• SmartSlot for expandability: A built-in SmartSlot lets you add network management cards or other modules for remote monitoring, graceful shutdowns, and integration with your existing IT management stack, enabling proactive power protection across the campus or data center.
• Extended runtime (with external battery modules): Designed to scale with your uptime needs, the UPS supports extended runtime configurations when paired with compatible external battery modules (EBMs), helping you cover longer outages and perform orderly maintenance without data loss or downtime.
• Tower design with no rail kit required: The vertical tower form factor fits compact server rooms and workspaces, delivering reliable backup power without requiring a separate rack or rail kit. It’s easy to place on a floor stand or a stable surface and connect to a critical gear layout.

How to Install APC Smart-UPS On-Line, 3kVA Tower, 120V, 8x 5-20R + 1x L5-30R NEMA Outlets, SmartSlot, Extended Runtime, W/O Rail Kit

• Unbox and place the UPS on a stable, well-ventilated surface in proximity to the equipment being protected. Ensure there is adequate clearance for airflow and access to the outlets and SmartSlot.
• Connect the UPS to a dedicated 120V circuit using the included L5-30P input plug. Confirm that the circuit can handle the combined load of the UPS and any connected devices.
• Attach the devices you want protected to the eight 5-20R outlets and the critical equipment to the L5-30R outlet as needed. Distribute loads to avoid overloading any single outlet or circuit.
• If you plan to use extended runtime, connect compatible external battery modules (EBMs) per the manufacturer’s guidance. Ensure proper battery management and secure mounting if required by your environment.
• Install a SmartSlot management card (if desired) to enable remote monitoring, automated shutdown, and integration with your IT management platform. Configure the card according to the provided user guide and your network settings.

Frequently asked questions

• What does 3 kVA mean for this UPS? The 3 kVA rating indicates the maximum apparent power the UPS can deliver to connected equipment. In practice, it supports a typical load around 2.7 kW, with headroom for startup surges. This rating is suitable for protecting servers, storage devices, switches, and other critical IT gear in small data environments.
• What is the purpose of the SmartSlot? The SmartSlot provides an extensible path to add network management capabilities, remote monitoring, and shutdown features. This enables centralized power protection management across multiple devices and sites from a single interface.
• What outlets are included? The UPS includes eight NEMA 5-20R outlets for standard devices and one NEMA L5-30R outlet for higher-current equipment. This mix supports a compact, versatile power distribution strategy for mixed IT gear.
• Can I extend runtime? Yes. The unit is designed for extended runtime with external battery modules. By adding EBMs, you can cover longer outages, providing extra time to save work, perform orderly shutdowns, or continue essential services during a power interruption.
• Is a rail kit required? No, this model is specified as W/O rail kit, meaning it can operate effectively as a tower without needing rack rails. If you plan to mount it in a rack or require a different configuration, check for compatible options and installation guidance.
• How do I monitor and manage this UPS? A SmartSlot module enables network management; you can monitor battery health, runtime, input/output voltage, load, and alarms, and perform graceful shutdowns of connected equipment through compatible software and management tools.
• What environments is this UPS best suited for? It’s ideal for small data centers, server rooms, edge sites, and network closets where uptime is critical, loads are moderate, and reliable, clean power is essential to protect servers, NAS devices, switches, and network appliances.
