4. Setup

Follow these steps to properly set up your Green Cell PowerCore UPS.

4.1 Unpacking

• Carefully remove the UPS from its packaging.
• Inspect the unit for any signs of damage. If damaged, do not use and contact your vendor.
• Retain packaging for future transport or storage.

4.2 External Battery Connection

This UPS requires an external 24V battery system. You will need two 12V lead-acid batteries connected in series to achieve 24V. The UPS will not function without a connected external battery.

An example of a compatible external AGM lead-acid battery (12V 7Ah). Two such 12V batteries are needed for a 24V system.

1. Ensure the UPS is turned off and disconnected from the mains power.
2. Connect two 12V batteries in series to create a 24V battery bank. Connect the positive terminal of the first battery to the negative terminal of the second battery.
3. Connect the remaining positive terminal of the battery bank to the + (red) terminal on the rear of the UPS.
4. Connect the remaining negative terminal of the battery bank to the - (black) terminal on the rear of the UPS.
5. Double-check all connections for correct polarity and secure fastening.

4.3 Mains Power Connection

1. Plug the UPS's input power cord into a grounded 230V AC wall outlet.
2. The UPS will typically enter charging mode, indicated on the LCD.

4.4 Connecting Devices

1. Plug your electronic devices (computer, monitor, router, etc.) into the 230V output sockets on the rear panel of the UPS.
2. Ensure the total power consumption of all connected devices does not exceed 1200W.

5. Operation

5.1 Powering On/Off

• To Power On: Press and hold the power button on the front panel for approximately 3 seconds until the LCD illuminates and the UPS starts.
• To Power Off: Press and hold the power button for approximately 3 seconds until the LCD turns off.

5.2 LCD Display

The LCD provides real-time status information:

• Input Voltage: Displays the current voltage from the mains power supply.
• Output Voltage: Shows the voltage being supplied to connected devices.
• Load Level: Indicates the percentage of the UPS's capacity currently being used by connected devices.
• Battery Capacity: Shows the remaining charge level of the external battery.
• Status Indicators: Icons for Utility Line (mains power), Battery Mode, Overload, Fault, and Check.

5.3 Charging Current Adjustment

The rear panel features a three-level switch (Low/Medium/High) to adjust the battery charging current. Select the appropriate setting based on your external battery's specifications and charging requirements. A higher current will charge faster but may generate more heat.

5.4 Audible Alarm Control

The audible alarm switch on the front panel allows you to mute or enable the alarm sounds. This is useful for silencing alerts during power events if immediate attention is not required.

5.5 Pure Sine Wave Output

The PowerCore UPS provides a pure sine wave output, which is identical to the waveform of standard utility power. This ensures compatibility and safe operation for sensitive electronics, including active PFC power supplies found in modern computers, servers, and other critical equipment, preventing potential damage or operational issues.

6. Maintenance

6.1 Battery Care

• Regularly check the external battery terminals for corrosion and ensure connections are secure.
• Ensure the batteries are kept in a cool, dry, and well-ventilated area.
• Periodically allow the UPS to discharge the batteries under load to calibrate the battery meter and ensure optimal performance.

6.2 Cleaning

• Disconnect the UPS from all power sources before cleaning.
• Use a soft, dry cloth to wipe the exterior of the unit.
• Do not use liquid or aerosol cleaners.
• Keep the cooling fan vents clear of dust and obstructions to ensure proper airflow.

6.3 Fuse Replacement

The UPS features a removable DC fuse for battery reverse protection. If the fuse blows, disconnect the UPS from all power sources and the external battery. Replace the fuse with one of the same type and rating. Consult the specifications section for fuse details or contact support.
