User Manual for Eaton Castle 1-3K G2 Online UPS

Quick Guide from the Manual

The Eaton Castle 1-3K G2 is an online double-conversion UPS designed to protect critical equipment. Before first use, it is recommended to charge the internal batteries for at least 10 hours. Ensure the installation environment is cool, dry, and well-ventilated, maintaining at least 250mm of clearance behind the unit for heat dissipation. Always verify that the input voltage and power requirements match your local power grid.

Product Overview

This series includes tower (FG2) and rack-mount (RM) models ranging from 1KVA to 3KVA. The system features DSP digitization and high-frequency sine wave inversion to provide clean, stable power. It supports TN, IT, and TT power distribution systems.

Installation

Rack Installation: Use the optional rail kit. Install M5 floating nuts into the rack columns, adjust the rails to the cabinet depth, and secure them with M5 screws. Attach the mounting ears to the UPS sides before sliding the unit into the rails.

Wiring: Ensure the UPS is powered off during installation. Connect the input power cable to the appropriate outlet. For models with terminal blocks, ensure correct wire gauge (e.g., 12AWG or 10AWG depending on model) and torque (0.5Nm). Always connect the output devices to the UPS output terminals or sockets, ensuring the total load does not exceed the rated capacity.

Operation and LCD Panel

The LCD panel displays input/output parameters, load percentage, battery status, and fault codes. Use the buttons to navigate:

• On/Off Button: Long press for 3 seconds to power on or off.
• Enter Button: Long press for 5 seconds to enter settings mode.
• Up/Down Buttons: Used for page navigation, battery self-test, and silencing alarms.

Settings

In settings mode, you can configure:

• Output Voltage: 110V, 120V, or 125V.
• Output Frequency: Auto-sensing, 50Hz, or 60Hz.
• Auto-Restart (SON): Enable/Disable automatic startup when AC power returns.
• EPO/ROO: Configure Emergency Power Off and Remote On/Off settings.
• ECO Mode: Enable/Disable energy-saving mode.
• Bypass: Enable/Disable bypass output.

Maintenance

Battery Maintenance: The internal batteries are sealed lead-acid. Keep the environment between 15°C and 25°C. If the UPS is not used for a long period, charge it every 6 months. Under normal use, perform a battery discharge/charge cycle every 4-6 months. Battery replacement must be performed by authorized personnel.

Troubleshooting

If a fault occurs, check the fault code on the LCD:

• 01: Startup failure (check battery voltage).
• 10: Output short circuit (remove shorted device).
• 22: Overload (remove unnecessary loads).
• 23: Over-temperature (check ventilation, wait 10 minutes).
• 57: Battery not connected or weak.
