APC Smart-UPS RT 6kVA 208V Rack UPS (3U) with 4x 5-20R, 1x L6-30R, 1x L14-30R

The APC Smart-UPS RT 6kVA 208V Rack UPS is engineered to protect mission‑critical equipment where uptime is non‑negotiable. Built around true online double‑conversion technology, it delivers a pristine, continuous power signal even when the main supply fluctuates, dips, or experiences brief outages. This means servers, networking gear, medical devices, and light industrial equipment stay online long enough for safe shutdowns, data protection, and smooth maintenance windows. Designed in a compact 3U rack footprint, it fits neatly into standard 19-inch racks, preserving space for other critical devices while delivering robust, scalable protection. The 6kVA rating provides ample headroom for peak loads and future growth, and the versatile outlet arrangement—four 5‑20R receptacles plus one L6‑30R and one L14‑30R NEMA outlet—offers flexible connection options for servers, switches, storage units, and power‑intensive lab devices. With 208/240 VAC split‑phase input and 120 VAC output, it aligns with common data center and lab power architectures, reducing voltage stress on connected gear while delivering clean, regulated power. When business continuity matters, you can expand runtime with compatible battery modules so hours—not minutes—of backup are available for critical workloads, remote sites, or during extended maintenance. In short, this UPS is built to safeguard sensitive equipment, minimize the risk of data loss, and keep essential systems running through power disturbances with predictable, manageable performance.

• High‑density online protection: True online double‑conversion topology isolates your loads from input disturbances, delivering a clean sine wave output and seamless continuity during outages, middleware errors, or voltage sags—crucial for servers, storage, VOIP, and ICU/lab equipment.
• 3U rack‑mount form factor with scalable protection: The compact 3U footprint fits standard 19" racks while offering plenty of headroom for current loads and future expansion, ensuring critical gear remains protected without compromising rack space or airflow.
• Flexible outlet configuration: Equipped with 4x 5‑20R standard outlets for fleet‑load devices, plus 1x L6‑30R (30A 240V) and 1x L14‑30R (30A 120/240V) outlets to accommodate diverse power needs. This mix simplifies cabling, reduces adapters, and keeps high‑demand peripherals wired to appropriate circuits.
• Split‑phase voltage management: Input supports 208/240 VAC split‑phase, delivering stable 120 VAC outputs to sensitive equipment. This configuration is ideal for data centers, medical labs, and labs with mixed equipment that require reliable voltage regulation and clean power for critical operations.
• Expandable runtime and remote management: When uptime extends beyond minutes, add compatible battery modules to deliver hours of runtime for planned maintenance or extended outages. The Smart‑UPS RT also supports remote monitoring and management, enabling proactive alerts, load balancing, and safe shutdowns through integrated software or network management options.

how to install APC Smart-UPS RT 6kVA 208V Rack UPS

• Prepare the rack: Ensure the rack has adequate ventilation and clearance around the unit for cooling and service access. Confirm there is a stable 208/240 VAC split‑phase power source nearby and a dedicated circuit capable of supporting the UPS and connected loads.
• Mount the UPS: Install the 3U UPS into the rack using the supplied mounting rails. Align the chassis, secure it with screws, and verify that it sits level with unobstructed airflow on all sides.
• Connect the input power: Connect the UPS input to the 208/240 VAC supply via the appropriate circuit breaker. Ensure correct phase alignment and that the input cord and connectors are rated for the system’s maximum current to prevent nuisance tripping.
• Attach the protected devices: Distribute critical servers, storage, networking gear, and other equipment across the 5‑20R outlets as appropriate. Avoid exceeding the total rated UPS output to preserve protection during outages.
• Configure management and monitoring: Connect any USB or network management interfaces as needed. Install the vendor’s power management software and configure alerts, auto‑shutdown policies, and notification contacts for safe, automated responses during outages.
• Enable battery test and runtime planning: If you are using external battery modules or additional packs, connect them per the manufacturer’s instructions and run a self‑test to verify proper operation and runtime estimates under your typical load.
• Power on and verify: Turn on the UPS and observe initial startup indicators. Confirm normal operation, verify that the UPS passes self‑tests, and ensure all connected devices recover gracefully during a test power loss.
• Documentation and maintenance: Record the installation details, including outlet distribution, load per circuit, and planned battery replacement intervals. Schedule periodic self‑tests and battery health checks to maintain reliability over the lifecycle of the equipment.
