This document describes a Line-Interactive Uninterruptible Power Supply (UPS) system, available in models ranging from 425VA to 1000VA. This UPS is designed to provide stable power and protect connected equipment from power disturbances.
Function Description
The UPS provides continuous power to connected devices during power outages, sags, surges, and other electrical fluctuations. It features a line-interactive design, which means it can regulate voltage without always switching to battery power, thus extending battery life. The system automatically switches to battery mode when the utility power fails or fluctuates outside acceptable limits, providing backup power to allow for an orderly shutdown of connected equipment or to ride through short power interruptions.
Key operational features include:
- Automatic Voltage Regulation (AVR): The UPS regulates incoming voltage to provide a stable output, protecting sensitive electronics from voltage fluctuations.
- Battery Backup: Provides power from its internal battery during blackouts, sags, and severe brownouts.
- Surge Protection: Protects connected equipment from damaging power surges and spikes.
- Overload Protection: Shuts down or issues an alarm if the connected load exceeds the UPS's capacity.
- Cold Start Function: Allows the UPS to be started directly from its battery without utility power, useful for powering devices in areas without immediate grid access.
- Self-Test Function: Performs a diagnostic test of the UPS system, including the battery, to ensure proper operation.
- Audible Alarms: Provides audible alerts for various events such as battery mode, low battery, overload, and fault conditions.
- Communication Ports: Includes USB (optional) and RJ45/RJ11 ports for communication with a computer, allowing for monitoring and controlled shutdown of connected systems via UPSMON Pro software.

Usage Features
The UPS is designed for ease of use with clear indicators and simple controls.
- Front Panel: Features LED indicators (Green for Line Mode, Yellow for Battery Mode, Red for Overload/Fault) and a master button for UPS control (ON/OFF/TEST/Silence).
- Rear Panel: Provides multiple output receptacles (IEC, Schuko, or NEMA type depending on model/region), an input breaker, and a network transient protector. Some models also include an external battery port (optional) and a USB port for communication.
- Operation Modes:
- Line Mode (Green): UPS is operating with main power, charging the battery.
- Battery Mode (Yellow): UPS is operating from battery power during an outage.
- Overload (Red): Indicates the connected load exceeds capacity.
- Battery Fault (Red): Indicates a battery issue.
- Turning On/Off: Pressing the master button turns the UPS on or off. A "beep" alarm will sound, and the LED display will turn on/off.
- Self-Test: Pressing the master button for 3 seconds during Line/Battery-mode initiates a self-test.
- Silence Alarm: Pressing the master button briefly silences audible alarms.
- Green Mode: An energy-saving feature where the UPS can shut down its output if the load is low, and automatically restart when the load increases or utility power returns.
- UPS Monitoring Software (UPSMON Pro): Allows users to monitor UPS status, control shutdown, and set up alerts via a connected computer. This software provides detailed information about power conditions, battery status, and UPS performance.
Maintenance Features
Proper maintenance ensures the longevity and reliable operation of the UPS.
- Battery Maintenance:
- Battery Recharge: The battery automatically recharges when the UPS is connected to utility power. A full recharge typically takes 6-8 hours.
- Battery Replacement: Batteries are consumable items and have a limited lifespan (typically 3-5 years). The manual provides instructions for battery replacement, which should be performed by qualified personnel.
- Storage: If the UPS is stored, it should be fully charged every 3 months to prevent battery degradation.
- Cleaning: The UPS should be kept clean and free from dust. Ensure proper ventilation around the unit.
- Environmental Conditions:
- Temperature: Operate the UPS within the specified temperature range (0-40°C). Extreme temperatures can shorten battery life.
- Humidity: Maintain humidity levels within 0-90% (non-condensing).
- Location: Place the UPS in a well-ventilated area, away from direct sunlight, heat sources, and excessive moisture. Avoid placing it near equipment that generates strong electromagnetic fields.
- Troubleshooting: The manual includes a troubleshooting guide to help diagnose and resolve common issues such as power source mistakes, hardware failures, battery problems, and overload conditions.
- Service: For complex issues or repairs, contact a qualified service technician. Do not attempt to open the UPS cabinet or perform user-serviceable parts beyond battery replacement.
- Disposal: Batteries and the UPS itself contain hazardous materials and should be disposed of according to local regulations.
