4. Setup
4.1 Unpacking and Inspection
Carefully unpack the UPS and its accessories. Inspect for any shipping damage. Retain the packaging for future use or return.
4.2 Placement
Place the UPS in a well-ventilated area, away from direct sunlight, heat sources, and excessive dust or moisture. Ensure sufficient clearance around the unit for proper airflow.
4.3 Configuration (Tower/Rack-Mount)
The GXE3-1000IRT2UXL can be deployed as a tower unit using the included stands or installed in a standard 19-inch rack using an optional rack-mount kit (sold separately). Follow the instructions provided with the rack-mount kit for rack installation.
4.4 Electrical Connections
- Input Power: Connect the UPS input power cord to a grounded electrical outlet. Ensure the outlet provides the correct voltage (230V) and current capacity.
- Output Devices: Connect your critical IT equipment (servers, networking devices, etc.) to the IEC C13 output receptacles on the rear of the UPS. Do not overload the UPS beyond its rated capacity (900W).
- Communication Ports: For monitoring and management, connect the appropriate communication cables (USB, RS-232, or optional network card) to your computer or network.
4.5 Initial Power-Up
After all connections are secure, press the power button on the front panel to turn on the UPS. The LCD display will illuminate, and the UPS will perform a self-test. Allow the batteries to charge for at least 4 hours before connecting critical loads for optimal runtime.
5. Operating the UPS
5.1 LCD Display and Control
The user-friendly LCD display provides real-time status information, including input/output voltage, load level, battery capacity, and operational mode. Use the navigation buttons next to the LCD to scroll through menus and configure settings.
5.2 Operating Modes
- Online Mode (Double Conversion): The UPS continuously converts incoming AC power to DC to charge the batteries, and then converts DC back to clean AC power for connected devices. This provides the highest level of power protection.
- ECO Mode (Economy Mode): In ECO mode, the UPS operates with higher efficiency by bypassing the double conversion process when utility power is stable. It switches to online mode instantly upon detecting power anomalies.
5.3 Software Management
For enhanced monitoring and management, install the Vertiv Power Assist software on a connected computer for local control and graceful shutdown. For network-wide management, utilize Vertiv Power Insight or an optional Vertiv Liebert Intellislot IS-UNITY Network Management Card.
