4. Nastavení
4.1 Vybalení a kontrola
- 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.
- Ověřte, zda jsou přítomny všechny součásti uvedené v dodacím listu.
4.2 Umístění
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.
- Umístěte UPS do čistého, suchého a teplotně kontrolovaného prostředí.
- 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 Elektrické připojení
Veškeré elektrické připojení musí být provedeno kvalifikovaným elektrikářem v souladu s místními a národními elektrotechnickými předpisy.
- Vstupní výkon: 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.
- Výstupní výkon: Connect your critical loads to the UPS output terminals. Ensure the total load does not exceed the UPS's 40kVA/40kW capacity.
- Základy: Connect the UPS to a reliable earth ground.
- Připojení baterie: If external battery cabinets are used, connect them according to the separate battery cabinet manual. Ensure correct polarity.
- Komunikační připojení: 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 Počáteční zapnutí
- 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. Návod k obsluze
5.1 Zapnutí/vypnutí
- Zapnout: 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.
- Vypnout: 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.
- Nouzové vypnutí (EPO): In an emergency, activate the EPO switch. This will immediately shut down the UPS and disconnect power to the loads.
5.2 Monitorování
The UPS features an intuitive control panel and supports remote monitoring via the Liebert Intellislot Card (is-Unity-DP).
- Místní zobrazení: The front panel LCD provides real-time status, input/output voltage, zatížení procenttage, battery status, and alarm information. Navigate through menus using the control buttons.
- Vzdálený dohled: 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.
- Pokročilé monitorování baterie: The UPS continuously monitors battery capacity, temperature, humidity, and can detect access or leaks, providing early warnings for potential issues.
5.3 Provozní režimy
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.
- Režim ECO: 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.
