4. Impostazione

4.1 Disimballaggio e ispezione

• Carefully unpack the UPS and all accessories from its packaging.
• Inspect the unit for any signs of shipping damage. If damage is found, contact your carrier and supplier immediately.
• Verificare che tutti i componenti elencati nella lista di imballaggio siano presenti.

4.2 Posizionamento

The Vertiv Liebert EXS V-Model UPS is designed with a front-access configuration, allowing for flexible placement in various environments such as in-row or against a wall. This design eliminates the need for rear clearance, simplifying installation and serviceability.

• Place the UPS in a clean, dry, and temperature-controlled environment.
• Ensure adequate airflow around the unit. Maintain a minimum clearance of 10 cm (4 inches) on all sides for proper ventilation.
• The floor must be capable of supporting the UPS's weight (1609 pounds).
• Avoid locations with excessive dust, humidity, or corrosive substances.

4.3 collegamenti elettrici

Tutti i collegamenti elettrici devono essere eseguiti da un elettricista qualificato, in conformità con le normative elettriche locali e nazionali.

• Potenza in ingresso: Connect the 3-phase, 4-wire input power source (208/120VAC or 220/127VAC) to the designated input terminals on the UPS. Refer to Figure 3.4 for connection points.
• Potenza di uscita: Connect your critical loads to the UPS output terminals. Ensure the total load does not exceed the UPS's 40kVA/40kW capacity.
• Messa a terra: Connect the UPS to a reliable earth ground.
• Collegamenti della batteria: If external battery cabinets are used, connect them according to the separate battery cabinet manual. Ensure correct polarity.
• Connessioni di comunicazione: Install the Liebert Intellislot Card (is-Unity-DP) into the designated Intellislot port (refer to Figure 3.4) and connect necessary network cables for remote monitoring and management.

4.4 Accensione iniziale

• Before applying power, double-check all electrical connections for correctness and security.
• Ensure all internal breakers (RIB, MIB, BIB, MBB) are in the correct position as per the installation guide.
• Apply utility power to the UPS input. The UPS will perform a self-test.
• Follow the on-screen prompts on the UPS control panel to configure initial settings, such as date, time, and network parameters.
• Verify that the UPS is operating in normal mode and providing stable output power to the connected loads.

5. Istruzioni per l'uso

5.1 Accensione/Spegnimento

• Per attivare: Once input power is stable, the UPS will typically start automatically. If not, use the control panel to initiate startup. Follow the sequence displayed on the LCD.
• Per spegnere: To shut down the UPS, first transfer the load to bypass (if available and desired) via the control panel. Then, initiate a shutdown sequence from the control panel. Finally, disconnect the input utility power.
• Spegnimento di emergenza (EPO): In an emergency, activate the EPO switch. This will immediately shut down the UPS and disconnect power to the loads.

5.2 Monitoraggio

The UPS features an intuitive control panel and supports remote monitoring via the Liebert Intellislot Card (is-Unity-DP).

• Visualizzazione locale: The front panel LCD provides real-time status, input/output voltage, percentuale di caricotage, battery status, and alarm information. Navigate through menus using the control buttons.
• Monitoraggio remoto: The Liebert Intellislot Card (is-Unity-DP) enables network-based monitoring and management. This allows for remote access to UPS status, event logs, and configuration settings via web browser, SNMP, or other network protocols.
• Monitoraggio avanzato della batteria: The UPS continuously monitors battery capacity, temperature, humidity, and can detect access or leaks, providing early warnings for potential issues.

Modalità operative 5.3

The Liebert EXS V-Model UPS operates primarily in two modes:

• Double Conversion Mode: This is the standard operating mode, providing the highest level of power protection. Input AC power is converted to DC, then back to AC, isolating the load from utility disturbances. Efficiency is typically >93% in this mode.
• Modalità ecologica: For enhanced energy efficiency, the UPS can operate in ECO mode (up to 99% efficiency). In this mode, the UPS typically operates in bypass, and the inverter is only activated when the utility power falls outside predefined tolerances. This mode offers energy savings but with a slightly reduced level of power conditioning compared to double conversion mode.

6. Manutenzione

Regular maintenance ensures the longevity and reliable operation of your UPS. All maintenance procedures should be performed by qualified personnel.

6.1 Bypass di manutenzione integrato

The UPS features an integrated maintenance bypass cabinet, allowing the critical load to be transferred to the utility power source while the UPS is serviced. This ensures continuous operation of your equipment.

• Before performing any internal maintenance, ensure the load is safely transferred to the maintenance bypass.
• Follow the specific lockout/tagout procedures for the integrated maintenance bypass breakers (RIB, MIB, BIB, MBB) as detailed in the full product manual.

6.2 Manutenzione della batteria

The UPS uses Lead Acid batteries. While the advanced battery monitoring system provides alerts, periodic physical inspection and testing are recommended.

• Inspect batteries for signs of swelling, leakage, or corrosion.
• Ensure battery terminals are clean and tight.
• Perform battery discharge tests periodically to verify runtime capacity. Consult the full manual for recommended intervals and procedures.
• Replace batteries as recommended by Vertiv or when their performance degrades significantly.

6.3 Pulizia generale

• Keep the exterior of the UPS clean and free of dust. Use a soft, dry cloth.
• Ensure ventilation openings are clear of obstructions. Periodically clean air filters if present and accessible.
