2. Safety Information

Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Installation and maintenance should only be performed by qualified electricians.
• Ensure the power supply is completely disconnected before any installation, wiring, or maintenance work.
• Verify that the voltage and current ratings of the protector match your system requirements.
• Do not operate the device in wet or damp conditions.
• Do not disassemble or modify the device.
• Ensure proper grounding according to local electrical codes.

3. Product Features

The HONGTONGAAD Voltage Protector offers the following key features:

• Integrated overvoltage, undervoltage, and three-phase voltage protection.
• Adjustable parameters for overvoltage value, undervoltage value, overcurrent protection, and fault recovery delay time.
• Clear LCD display for real-time data monitoring and easy reading of voltage and current values for each phase.
• Automatic reclosing function: The protector automatically restores power when line voltage and current return to normal.
• Durable construction with low power consumption, ensuring a long mechanical life.
• Designed for Din Rail mounting, facilitating easy integration into electrical panels.

4. Package Contents

Upon opening the package, please verify that all components are present and undamaged:

• 1 x HONGTONGAAD 63A/100A Three Phase Din Rail Under Voltage and Over Voltage Protector

If any items are missing or damaged, please contact your supplier immediately.

5. Setup and Installation

This device is designed for standard 35mm Din Rail mounting. Follow these steps for proper installation:

1. Power Disconnection: Before starting any wiring, ensure that the main power supply to the circuit is completely disconnected and locked out to prevent accidental re-energization.
2. Mounting: Snap the protector onto a standard 35mm Din Rail within your electrical panel. Ensure it is securely fastened.
3. Wiring: Refer to the wiring diagrams below for correct connection of the input (L1, L2, L3, N) and output terminals. Pay close attention to the phase sequence and neutral connection.
   

   Figure 2: Detailed wiring diagrams for both 63A and 100A models. The left diagram shows connections for a 63A unit with neutral (N) for 3*230V, displaying each phase at 230V. The right diagram illustrates connections for a 100A unit without neutral (N) for 380V three-phase, displaying all phases at 380V.

4. Terminal Connections: Use appropriate wire gauges for the current rating (63A or 100A model) and ensure all terminal screws are tightened securely to prevent loose connections and overheating.
5. Verification: Double-check all wiring connections against the diagram before restoring power.

6. Operating Instructions

Once installed and powered on, the device will display real-time voltage and current readings on its LCD. Use the control buttons (typically marked with 'M', 'Up', 'Down', 'Set' or similar icons) to navigate menus and adjust settings.

6.1. Parameter Adjustment

The protector allows for customization of various protection parameters:

• Overvoltage Protection Value: Set the maximum allowable voltage. If the voltage exceeds this value, the protector will trip.
• Undervoltage Protection Value: Set the minimum allowable voltage. If the voltage drops below this value, the protector will trip.
• Overcurrent Protection Value: Set the maximum allowable current. If the current exceeds this value, the protector will trip.
• Fault Recovery Delay Time: Configure the delay before the device automatically recloses after a fault condition has cleared. This prevents rapid cycling and protects connected equipment.

Refer to the device's on-screen menu for specific navigation and adjustment procedures. Typically, pressing the 'M' or 'Set' button enters the setting mode, and 'Up'/'Down' buttons adjust values.

6.2. Automatic Recovery Function

The protector is designed to automatically restore power to the circuit once the detected voltage or current anomaly returns to within the safe operating parameters and after the set recovery delay time has elapsed. This feature ensures continuous operation without manual intervention after transient faults.

7. Maintenance

The HONGTONGAAD Voltage Protector is designed for minimal maintenance. However, periodic checks can ensure its continued reliable operation:

• Visual Inspection: Periodically inspect the device for any signs of physical damage, discoloration, or loose connections.
• Cleaning: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Connection Check: Ensure all wiring connections remain tight and secure. Loose connections can lead to overheating and malfunction.

Always disconnect power before performing any maintenance.

8. Troubleshooting

If the device is not functioning as expected, consider the following common issues and solutions:
