2. Safety Information

WARNING: Installation of this high-capacity UPS may require a dedicated 30A circuit and professional electrical installation. Consult a licensed electrician to ensure proper wiring and compliance with local electrical codes.

• Do not attempt to open or service the UPS enclosure. Hazardous voltage is present inside.
• Ensure the UPS is connected to a properly grounded electrical outlet.
• Position the UPS in a well-ventilated area, away from direct sunlight, excessive heat, or moisture.
• The unit is heavy (approximately 143 pounds). Use appropriate lifting techniques or assistance during installation to prevent injury.
• Do not connect non-computer related equipment, such as medical devices, life support equipment, or household appliances, to the UPS.

3. Product Overview

Figure 3.1: Front View
This image displays the front of the APC Smart-UPS SMT3000VA. It is a black, tower-style unit featuring an LCD control panel at the top, which provides status information and allows for configuration. The APC logo is prominently displayed below the control panel, and the model name 'Smart-UPS 3000' is visible at the bottom.

Figure 3.2: Rear View
This image shows the rear panel of the APC Smart-UPS SMT3000VA. It features a large cooling fan at the top, along with communication ports including a USB port and a SmartSlot for optional network management cards. Below these are two banks of output receptacles: eight NEMA 5-15R outlets and two NEMA 5-20R outlets. The main input power connector, a NEMA L5-30P, is located at the bottom left, alongside a resettable circuit breaker.

4. Setup and Installation

1. Unpacking and Placement: Carefully unpack the UPS. Due to its significant weight (approximately 143 lbs), ensure you have assistance for safe handling. Place the unit on a stable, level surface in a cool, dry, and well-ventilated environment.
2. Battery Connection: The UPS typically ships with the internal batteries disconnected for safety. Refer to the included quick start guide or the full installation manual for instructions on connecting the internal batteries.
3. Input Power Connection: Connect the UPS input power cord (NEMA L5-30P) to a dedicated 120V, 30A circuit. This connection requires a specific type of outlet and may necessitate professional electrical installation.
4. Connecting Equipment: Plug your critical equipment into the UPS output receptacles. The SMT3000VA provides eight NEMA 5-15R outlets and two NEMA 5-20R outlets. Ensure the total load does not exceed the UPS's capacity (2700W / 3000VA).
5. Initial Power-Up: Press the power button on the front panel to turn on the UPS. The LCD display will illuminate, and the unit will perform a self-test. Allow the batteries to charge for at least 3 hours before relying on the UPS for extended backup time.
6. Communication Ports: For advanced monitoring and management, connect the UPS to a computer via the USB or serial (DB-9 RS-232) port. An optional SmartSlot card can be installed for network management.

For detailed installation instructions, please refer to the official Installation Manual (PDF).

5. Operating Instructions

• LCD Display and Control Console: The multi-function LCD provides real-time status, configuration options, and diagnostic information. Use the navigation keys to browse menus and adjust settings.
• Green Mode: The UPS features a patent-pending operating mode that bypasses unused electrical components under good power conditions. This achieves very high operating efficiency without compromising protection.
• Pure Sine Wave Output: The SMT3000VA provides a pure sine wave output when operating on battery power, ensuring compatibility with all connected equipment, especially those with active PFC power supplies.
• Switched Outlet Group: A single outlet group can be controlled independently from the main UPS. This allows for discrete rebooting of hung devices, sequenced power-on/off, or non-critical load shedding to extend battery runtime.
• Cold-Start Capability: The UPS can be powered on and provide temporary battery power even when utility power is unavailable.
• Audible Alarms: The unit provides audible alarms to notify users of changing utility power conditions, UPS status, and low battery warnings. These alarms can often be configured for delays or silenced via the LCD.
• Automatic Voltage Regulation (AVR): The Boost and Trim AVR feature automatically corrects low and high input voltages without switching to battery power, preserving battery life.
• Network Management: The UPS can be managed remotely via serial, USB, or an optional Ethernet connection (SmartSlot card required).

6. Maintenance

• Battery Recharge: The typical recharge time for the maintenance-free sealed Lead-Acid battery is 3 hours.
• Predictive Battery Replacement: The UPS provides a predictive battery replacement date, indicating the month and year when battery replacement is recommended.
• Automatic Self-Test: The UPS performs periodic battery self-tests to ensure early detection of a battery that needs replacement.
• Hot-Swappable and User-Replaceable Batteries: Batteries can be replaced without powering down connected equipment, ensuring continuous power. Trained users can perform battery upgrades and replacements.
• Temperature-Compensated Charging: This feature prolongs battery life by regulating the charge voltage based on battery temperature.
• Cleaning: Keep the ventilation openings clear of dust and debris to ensure proper airflow and cooling.

7. Troubleshooting

• Audible Alarms: If the UPS emits continuous or intermittent alarms, consult the LCD display for specific error messages. Common alarms include low battery, overload, or internal fault.
• No Power Output: Check the input power connection and ensure the UPS is turned on. Verify that the resettable circuit breakers on the rear panel have not tripped.
• Disconnected Battery Notification: If this alarm occurs, ensure the internal batteries are properly connected.
• Unexpected Shutdowns: Ensure the connected load does not exceed the UPS capacity. Check for configurable settings related to load shedding or automatic shutdowns after a certain period on battery power, which can be adjusted via the LCD or management software.
• Battery Not Charging: Verify the UPS is connected to a live utility power source. If the issue persists, the battery may need replacement.
