2. Product Overview
The TOMZN TZG40-T1T2 is a high-performance surge protective device (SPD) that integrates both Type 1 (T1) and Type 2 (T2) protection into a single compact unit. It provides comprehensive defense against direct lightning strikes and induced surge voltages. Designed for installation at the main distribution board, it safely dissipates high-energy lightning impulse currents (Iimp) while effectively limiting transient overvoltages.
This model is specifically configured for DC power systems, with a rated voltage of 1000V/1200V DC and a 3-pole design, making it ideal for photovoltaic (PV) systems, energy storage installations, and other DC applications. It complies with IEC/EN 61643-11 standards, offering reliable, space-saving protection for residential, commercial, and industrial DC power distribution.
The surge protector silently guards appliances by quickly unloading voltage within 25 nanoseconds during a lightning strike.
3. Setup and Installation
- Upon receiving the product, ensure that a qualified electrical professional performs the installation and operation.
- Connect the equipment strictly in accordance with the provided wiring diagram specifications.
- Mount the device on a standard 35mm DIN rail within the main distribution board.
- Adjust any necessary equipment parameters according to specific system requirements.
Wiring Diagram
The TZG40-T1T2 features DC+ (Positive Input), PE (Ground Wire), and DC- (Negative Input) terminals. Ensure correct polarity and secure connections.
Wiring connections: Positive input to DC+, Negative input to DC-, and Ground wire to PE. Ensure to screw down firmly to penetrate the insulating layer of power lines.
The surge protector installed as the first line of defense in a main distribution box.
The device is designed for easy rail mounting on a standard 35mm DIN rail.
4. Operation
The TZG40-T1T2 DC Surge Protector operates automatically. When a surge occurs in the circuit, the device will immediately cut off the power to protect connected equipment.
Visual Warning Module
The device is equipped with a visual indicator to show its operational status:
- Green Indicator: Indicates normal working condition. The device is fully functional and providing protection.
- Red Indicator: Indicates a working state failure. The lightning protection module has been compromised and needs replacement.
The visual warning module clearly indicates the device's status: Green for normal, Red for failure.
5. Maintenance
The TZG40-T1T2 is designed for simple installation and easy maintenance.
- Regular Inspection: Periodically check the visual warning module. If the indicator is red, the lightning protection module has failed and requires replacement.
- Module Replacement: The modular design allows for easy replacement of failed protection modules. Ensure power is disconnected before attempting any module replacement.
- Physical Inspection: Regularly inspect the device for any physical damage, discoloration, or loose connections.
- Ventilation: Ensure that the area around the device remains clear to allow for adequate ventilation.
6. Troubleshooting
- Problem: Device indicator is red.
Solution: The visual warning module indicates a failure. The lightning protection module has been compromised and needs to be replaced. If the entire protector is physically damaged, it should be replaced. - Problem: Power interruption without a visible surge event.
Solution: Check the upstream circuit breaker or fuse in your electrical panel. Ensure all wiring connections to the surge protector are correct and secure. If the issue persists, consult a qualified electrician.
