Setup Instructions
1. Placement
- Place the UPS on a flat, stable surface.
- Ensure the environment is well-ventilated and free from excessive dust or moisture.
- Maintain at least 20 cm (8 inches) of clearance from the rear and sides of the UPS for proper airflow.
- Avoid placing the UPS near heat-emitting appliances.
2. Connecting to Power
- Connect the provided power input cable to the UPS input receptacle on the rear panel.
- Plug the other end of the power input cable into a grounded wall outlet.
- Allow the UPS to charge for at least 8 hours before initial use to ensure optimal battery performance.
3. Connecting Devices
- Plug your critical devices (e.g., computers, servers, network equipment) into the Type F output receptacles on the rear panel of the UPS.
- Ensure that the total load connected to the UPS does not exceed its rated capacity (2700W for this model).
- For devices requiring terminal output, connect them according to electrical safety standards.
4. Initial Startup
- After connecting the UPS to AC power and allowing initial charging, press and hold the ON button on the front panel for approximately 2 seconds.
- The UPS will perform a self-test, and the LCD display will illuminate, indicating operational status.
- The UPS is now providing protected power to the connected devices.
Operating the UPS
Turning On/Off
- To Turn On: Press and hold the ON button for 2 seconds.
- To Turn Off: Press and hold the OFF button for 2 seconds. The UPS will shut down, and power to connected devices will cease.
Understanding the LCD Display
The LCD display provides critical information about the UPS status. Use the ENTER and ESC buttons to navigate through different display screens, which may include:
- Input Voltage and Frequency
- Output Voltage and Frequency
- Battery Charge Level
- Load Percentage
- Operating Mode (Online, Battery, Bypass)
- Error Codes (if any)
Battery Backup Operation
In the event of a power outage or significant voltage fluctuation, the UPS will automatically switch to battery power to provide continuous power to connected devices. An audible alarm may sound, and the LCD will indicate "Battery Mode." The duration of battery backup depends on the load connected and the battery charge level.
Communication Software
For advanced monitoring and management, install the provided communication software on a computer connected to the UPS via the USB or RS-232 port. This software allows for scheduled shutdowns, remote monitoring, and detailed event logging.
Maintenance
Battery Care
- Ensure the UPS is connected to AC power at all times to keep the batteries fully charged.
- Perform a battery self-test periodically (e.g., once every 3 months) using the UPS front panel controls or communication software to verify battery health.
- Batteries have a limited lifespan. If the battery backup time significantly decreases, contact qualified service personnel for replacement.
Cleaning
- Disconnect the UPS from AC power and all connected devices before cleaning.
- Use a soft, dry cloth to wipe the exterior of the UPS.
- Do not use liquid or aerosol cleaners, as they may damage the unit.
- Periodically clean the ventilation grilles to prevent dust buildup, which can impede airflow and cause overheating.
Storage
- If storing the UPS for an extended period, ensure the batteries are fully charged.
- Store the UPS in a cool, dry place.
- Recharge the batteries every 3 months during storage to prevent deep discharge and prolong battery life.
Troubleshooting
