4.1. Unpacking
Carefully unpack the UPS and inspect it for any shipping damage. Retain the original packaging for future use or transport.
4.2. Placement
Place the UPS in a clean, dry, and well-ventilated area. Ensure sufficient clearance around the unit for proper airflow. Avoid placing it near heat sources or in direct sunlight.
4.3. Connecting to Power
- Connect the UPS to a grounded AC power outlet using the provided power cord.
- Allow the UPS to charge for at least 4 hours before initial use to ensure optimal battery performance.
4.4. Connecting Equipment
Connect your critical electronic devices (e.g., computers, monitors, servers) to the Schuko output outlets on the rear panel of the UPS.
5. Operation
5.1. Turning On/Off
- To Turn On: Press and hold the ON/MUTE button until you hear a beep. The UPS will perform a self-test and then enter AC mode.
- To Turn Off: Press and hold the OFF/ENTER button until the UPS shuts down.
5.2. LCD Display
The LCD display provides real-time status information about the UPS, including:
- Load Level
- Battery Level
- AC Mode
- Battery Mode
- Bypass Mode
- Fault Indicators
5.3. Eco Mode
The Eco Mode feature helps reduce energy consumption. When the input voltage is within the acceptable range, the UPS will bypass the inverter to save energy, increasing overall efficiency.
6. Software Management
The NJOY Aten Pro 3000VA UPS includes management software for comprehensive monitoring and control. This software can be accessed via serial (RS232), USB, or an optional Ethernet (SNMP card) connection.
