- Output Terminal Block: For connecting critical loads to the UPS output.
4. Setup
4.1 Unpacking and Inspection
- Carefully unpack the UPS and external battery cabinet from their packaging.
- Inspect for any shipping damage. If damage is found, do not install and contact your dealer.
- Ensure all components listed in the packing list are present.
4.2 Placement
- Place the UPS and battery cabinet in a clean, dry, and well-ventilated area.
- Avoid direct sunlight, heat sources, and excessive humidity.
- Ensure the ambient temperature is within the recommended operating range (typically 0°C to 40°C).
4.3 Battery Connection
Connect the external battery cabinet to the main UPS unit according to the instructions provided with the battery cabinet. Ensure correct polarity and secure connections. The system requires an external battery voltage of 192V.
4.4 Power Connections
- Connect the UPS input power cord to a grounded AC power outlet. The UPS supports an input voltage range of 110-300VAC.
- Connect your critical equipment (servers, computers, networking devices) to the output terminal block of the UPS. Ensure the total load does not exceed the UPS capacity of 6KVA/5400W.
4.5 Initial Power-On
After all connections are secure, turn on the input protection switch on the rear panel. The UPS will perform a self-test and the display panel will illuminate. Allow the batteries to charge for at least 8 hours before using the UPS for backup power.
5. Operating Instructions
5.1 Turning On/Off
- To Turn On: Press and hold the power button on the front panel for a few seconds until the UPS powers on.
- To Turn Off: Press and hold the power button on the front panel for a few seconds until the UPS powers off.
5.2 Display Panel
The front display panel provides real-time information on UPS status, input/output voltage, battery level, and load capacity. Refer to the detailed display guide for specific icon meanings and navigation.
5.3 Automatic Voltage Regulation (AVR)
The UPS features automatic voltage adjustment to stabilize incoming utility power, protecting connected equipment from voltage fluctuations without switching to battery power.
5.4 Bypass Function
The UPS includes a bypass function, allowing power to flow directly from the utility to the connected equipment, bypassing the UPS inverter. This can be used for maintenance or in case of an internal UPS fault.
6. Maintenance
6.1 Battery Care
- Regularly check the battery status via the UPS display or monitoring software.
- Ensure batteries are kept at optimal operating temperatures to prolong their lifespan.
- Replace batteries when their performance degrades significantly.
6.2 Cleaning
Keep the UPS and battery cabinet clean and free of dust. Use a dry cloth to wipe surfaces. Do not use liquid cleaners or solvents.
6.3 Environmental Considerations
Ensure the UPS operates within its specified environmental conditions to maintain optimal performance and longevity.
