Key Components:
- Power Outlets: Provide battery backup and surge protection for connected devices.
- USB Port: For connecting to a computer to enable UPS monitoring software (if applicable).
- AC Input: Connects the UPS to the main utility power.
- Circuit Breaker: Provides overload protection. Resets the UPS if an overload occurs.
- Power Button: Turns the UPS on or off. Includes an LED indicator for operational status.
4. Setup
- Unpacking: Carefully remove the UPS from its packaging. Inspect for any shipping damage.
- Placement: Place the UPS on a flat, stable surface in a well-ventilated area, away from direct sunlight, excessive heat, dust, or moisture. Ensure there is sufficient space around the unit for proper airflow.
- Initial Charging: Before initial use, connect the UPS to a standard grounded AC wall outlet for at least 8 hours to ensure the battery is fully charged. The UPS will charge whether it is turned on or off.
- Connecting Equipment:
- Plug your computer, monitor, and other critical electronic devices into the UPS power outlets.
- Do not connect surge strips or extension cords to the UPS outlets.
- Ensure the total power consumption of connected devices does not exceed the UPS's capacity (480W).
- USB Connection (Optional): If you wish to use the UPS monitoring software, connect the USB cable (not included) from the UPS's USB port to your computer's USB port. Install the appropriate software provided by Phasak (if available) or compatible UPS monitoring software.
5. Operating Instructions
- Turning On the UPS: After connecting to AC power and charging, press and hold the Power Button for approximately 2 seconds until you hear a beep and the LED indicator illuminates.
- Turning Off the UPS: Press and hold the Power Button for approximately 2 seconds until you hear a beep and the LED indicator turns off.
- Normal Operation: When the UPS is connected to AC power and turned on, it provides conditioned power to your connected devices and charges its internal battery. The LED indicator will typically be solid green.
- Battery Mode: During a power outage or significant voltage fluctuation, the UPS will automatically switch to battery power. You will hear an audible alarm (beeping) and the LED indicator may change color or flash. This provides time to save your work and properly shut down your equipment.
- Overload Protection: If the connected load exceeds the UPS's capacity, the circuit breaker may trip. Disconnect non-essential equipment, then press the red Circuit Breaker button to reset the UPS.
6. Maintenance
- Battery Care: To maximize battery life, keep the UPS connected to an AC outlet at all times. If the UPS is stored for an extended period, recharge the battery every three months for at least 8 hours.
- Cleaning: Disconnect the UPS from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners.
- Battery Replacement: The internal battery is not user-replaceable. Contact qualified service personnel for battery replacement. Improper replacement can lead to hazards.
- Storage: Store the UPS in a cool, dry place with adequate ventilation. Ensure the battery is fully charged before storage.
