- Power Button: Used to turn the UPS on or off.
- LED Indicators: Provide visual status of the UPS.
- Green LED: Indicates the UPS is on and operating in Line Mode (receiving utility power).
- Yellow LED: Indicates the UPS is operating in Battery Mode (during a power outage) or a fault condition.
- Red LED: Indicates a low battery condition or a battery that needs replacement.
4.2 Rear Panel
The rear panel of the UPS contains the input power connection and output receptacles.
- AC Input: Connects the UPS to the utility power outlet.
- Output Receptacles (6 Tomas): Provide battery-backed and surge-protected power to connected equipment.
- Circuit Breaker: Provides overload protection for the UPS.
5. Setup
5.1 Placement
- Place the UPS on a flat, stable surface.
- Ensure adequate airflow around the unit. Do not block ventilation openings.
- Avoid placing the UPS near water, excessive heat, or direct sunlight.
5.2 Connecting to Power
- Connect the supplied AC power cord to the UPS AC input port.
- Plug the other end of the AC power cord into a grounded wall outlet.
- Allow the UPS to charge for at least 8 hours before initial use to ensure optimal battery runtime.
5.3 Connecting Equipment
- Plug your computer, monitor, and other critical electronic devices into the 6 output receptacles on the rear panel of the UPS.
- Ensure that the total power consumption of all connected devices does not exceed the UPS's capacity (1200VA / 660W).
6. Operation
6.1 Turning the UPS On/Off
- To Turn On: Press and hold the power button for approximately 2 seconds until you hear a beep and the green LED illuminates.
- To Turn Off: Press and hold the power button for approximately 2 seconds until you hear a beep and all LEDs turn off.
6.2 Indicator Lights and Audible Alarms
The LED indicators and audible alarms provide real-time status of the UPS:
- Green LED On: UPS is on and providing utility power (Line Mode).
- Yellow LED On & Beeping (every 10 seconds): UPS is operating on battery power (Battery Mode) due to a power outage or severe voltage fluctuation.
- Red LED On & Beeping (every 1 second): Battery is low. Save your work and shut down connected equipment immediately.
- Red LED Flashing & Continuous Beep: UPS fault or battery needs replacement. Contact support.
6.3 Automatic Voltage Regulation (AVR)
The Ablerex AB-ES1200 features AVR technology, which automatically corrects minor voltage fluctuations (sags and surges) without switching to battery power. This extends battery life and ensures a stable power supply to your devices.
6.4 Battery Backup Function
During a power outage, the UPS will automatically switch to battery power, providing a temporary power supply to your connected devices. This allows you sufficient time to save your work and safely shut down your equipment.
7. Maintenance
7.1 Battery Care
- To maintain optimal battery life, ensure the UPS is connected to AC power at all times, allowing the battery to remain charged.
- If the UPS is stored for an extended period, recharge the battery every three months for at least 8 hours.
- Replace the battery when the red LED indicates a fault or low battery condition persists after recharging. Battery replacement should be done by qualified personnel.
7.2 Cleaning
- Always turn off the UPS and disconnect it from the AC power outlet before cleaning.
- Use a dry, soft cloth to clean the exterior of the UPS.
- Do not use liquid or aerosol cleaners, as they may contain flammable substances or cause electrical shock.
