4. Setup
4.1 Unpacking and Placement
- Carefully unpack the UPS and inspect it for any shipping damage. If damage is found, do not operate the unit and contact your dealer.
- Place the UPS on a flat, stable surface in a clean, dry, and well-ventilated area. Avoid direct sunlight, heat sources, and excessive dust.
- Ensure there is adequate space around the UPS for proper airflow.
4.2 Connecting to Power and Devices
- Connect the UPS power cord to a grounded wall outlet.
- Connect your computer, monitor, and other critical devices to the backup outlets on the rear panel of the UPS.
- For network/phone line surge protection, connect your network cable or phone line through the RJ45 IN and OUT ports on the UPS.
- If desired, connect the USB cable from the UPS to your computer for monitoring and control software functionality.
4.3 Initial Charging
Before initial use, allow the UPS to charge for at least 4-6 hours with the power cord connected to a wall outlet, even if the UPS is turned off. This ensures the battery is fully charged and ready to provide optimal backup time.
4.4 Software Installation
For advanced monitoring and control features, install the ViewPower software on your computer. This software allows you to monitor UPS status, schedule shutdowns, and configure various settings. Ensure you use the correct version of ViewPower (e.g., ViewPower, not ViewPowerPro) compatible with your operating system.
5. Operation
5.1 Turning On/Off
- To Turn On: Press and hold the power button on the front panel for approximately 3 seconds until you hear a beep and the indicators light up.
- To Turn Off: Press and hold the power button for approximately 3 seconds until the indicators turn off.
5.2 LED Indicators
The front panel LEDs provide visual status of the UPS:
- AC Mode: Indicates the UPS is operating on utility power.
- Battery Mode: Indicates the UPS is operating on battery power during an outage.
- Fault/Warning: Indicates an error or warning condition. Refer to the troubleshooting section.
5.3 Automatic Voltage Regulation (AVR)
The UPS automatically regulates incoming voltage fluctuations to provide a stable output to connected devices without switching to battery power, thus preserving battery life.
5.4 Battery Backup Mode
During a power outage, the UPS will automatically switch to battery power, providing continuous power to connected devices. An audible alarm will sound to indicate battery mode. The alarm will typically sound more frequently as the battery level depletes, signaling an impending shutdown.
6. Maintenance
6.1 Battery Care
- To maintain optimal battery performance, keep the UPS connected to an AC outlet at all times to ensure the battery remains charged.
- If the UPS is stored for an extended period, recharge the battery every three months for at least 24 hours to prevent battery degradation.
- Battery lifespan is typically 3-5 years under normal operating conditions. Replace batteries when their capacity significantly diminishes.
6.2 Cleaning
Use a soft, dry cloth to clean the exterior of the UPS. Do not use liquid or aerosol cleaners. Ensure the UPS is turned off and disconnected from the AC power source before cleaning.
