## Long description

Vision Dual — Riello VSD 1100 is a Line-Interactive UPS with 1.1 kVA (990 W) capacity designed for protection of floor-standing or rackmount servers, network devices and storage systems. The unit is available in tower or 19" rack format, features 8 AC outlets and sealed lead‑acid batteries with a typical 4-hour recharge time. VSD 1100 integrates Riello's AVR, EMI filtering and inverter output that provides a true sinewave on battery to ensure continuity and reliable supply to connected equipment.
Advantages
The Vision Dual series offers high operating efficiency (up to 98%) and a 0.9 output power factor, reducing energy losses while delivering stable power. Built‑in AVR and EMI filters stabilise voltage and protect equipment from brownouts, sags, surges and transient spikes. EnergyShare load‑shedding and hot‑swappable batteries increase availability, while predictive battery testing and deep‑discharge protection help extend battery life. The front panel display is removable and rotatable for flexible installation and the unit supports cold‑start and Emergency Power Off functions.
Suitable for
Small rack or tower servers
Network switches, routers and firewalls
NAS and local storage systems
Workstations and point‑of‑sale terminals requiring short runtime backup

How to use
Install the VSD 1100 either as a tower or mount it in a 19" rack according to the mechanical instructions. Connect critical equipment to the UPS output sockets and plug the UPS into the mains supply. Configure communication via USB or RS‑232 and install PowerShield³ software if automatic supervised shutdown is required. Use the front panel to monitor statuses, measurements and alarms; the display can be removed and rotated for easier viewing in rack installations. For battery replacement, open the front panel and hot‑swap the battery following the safety steps in the manual.
Usage recommendations
For maximum availability, connect non‑critical loads to the EnergyShare output so the UPS can shed those loads during mains failure and preserve runtime for critical equipment. Periodically run the predictive battery test and replace batteries at the first sign of capacity loss. Ensure proper ventilation and follow Riello instructions for rack installation and battery handling.
