3. Setup

3.1 Unpacking and Inspection

Carefully unpack the UPS and inspect it for any damage that may have occurred during transit. If any damage is found, do not operate the unit and contact your vendor.

3.2 Placement

  • Place the UPS in a well-ventilated area, away from direct sunlight, heat sources, and excessive dust or moisture.
  • Ensure there is adequate space around the ventilation grilles for proper airflow.
  • The ambient humidity should be between 0% and 90% RH (non-condensing) and temperature between 0°C and 40°C.

3.3 Connecting the UPS

  1. Input Power Connection: Connect the UPS to a standard wall outlet using the provided power cord. The UPS features Automatic Bivolt input (110V - 220V), automatically adapting to the input voltage.
  2. Output Voltage Selection: Before connecting any devices, locate the Bivolt Keyed switch on the rear panel (refer to Figure 2). Set this switch to either 110V or 220V according to the voltage requirements of the devices you intend to connect to the UPS output. Incorrect selection can damage your equipment.
  3. Connecting Equipment: Plug your electronic devices (e.g., computer, monitor, router) into the output sockets on the rear panel of the UPS. Ensure the total load does not exceed the UPS's capacity (1500VA / 900W).
  4. Initial Charge: For optimal battery performance, allow the UPS to charge for at least 8 hours before initial use, even if the battery indicator shows full. This ensures the internal batteries reach their full capacity.

4. Operating Instructions

4.1 Turning On/Off the UPS

  • To Turn On: Press and hold the power button on the front panel for a few seconds until the display illuminates and the UPS beeps.
  • To Turn Off: Press and hold the power button again for a few seconds until the display turns off.

4.2 Understanding the Digital Display

The front digital display provides crucial information about the UPS status (refer to Figure 1):

  • INPUT VAC: Shows the current incoming utility voltage.
  • OUTPUT VAC: Displays the voltage being supplied to your connected devices.
  • UPS Status: Indicates if the UPS is operating on utility power or battery power.
  • POWER: May indicate the load percentage or power consumption.
  • Battery Level Indicator: Shows the approximate charge level of the internal batteries.

4.3 Operation Modes

  • Online Mode: When utility power is present and stable, the UPS operates in online mode, providing conditioned power to your devices and charging its batteries.
  • Battery Mode: In case of a power outage or significant voltage fluctuation, the UPS automatically switches to battery mode, supplying power from its internal batteries. The transfer time is typically 4-6 ms. The UPS will emit an audible alarm in this mode.
  • Battery Charging: The UPS will automatically charge its batteries when connected to utility power. It takes approximately 8 hours to recover 90% of the battery capacity.

5. Maintenance

5.1 Battery Care

  • To maximize battery lifespan, ensure the UPS is always connected to a power source to keep the batteries charged.
  • Avoid frequent deep discharges. If the UPS operates on battery power, save your work and shut down your equipment properly as soon as possible.
  • The UPS uses two 12V/9AH sealed lead-acid batteries. Battery replacement should be performed by qualified personnel.

5.2 Cleaning

  • Ensure the UPS is turned off and disconnected from the wall outlet before cleaning.
  • Use a soft, dry cloth to clean the exterior of the unit.
  • Do not use liquid or aerosol cleaners.
  • Keep the ventilation grilles clear of dust and obstructions to prevent overheating.

5.3 Storage

If storing the UPS for an extended period, ensure the batteries are fully charged. Recharge the batteries every three months to prevent permanent damage due to self-discharge.

6. Troubleshooting

This section addresses common issues you might encounter with your UPS. Refer to the digital display for diagnostic information.
