1. Introduction
The Wengart WG-40N is a comprehensive surge protection device (SPD) designed to safeguard electrical systems and equipment from lightning strikes and various transient overvoltages. It integrates the functions of a lightning arrester and a surge protector into a single unit, ensuring effective and economical protection for your electrical installations and household appliances.
This device is particularly suitable for environments where both lightning and non-lightning overvoltage protection are required, such as power distribution sides or common household electrical installations. It helps to minimize the risk of damage to sensitive electronic equipment.
2. Consignes de sécurité

5. Configuration et installation
The Wengart WG-40N is designed for DIN rail installation, making it compatible with standard electrical distribution boxes.
5.1 Montage sur rail DIN
Figure 3: DIN Rail Installation
To install the device, simply clip it onto a standard 35mm DIN rail within your electrical panel. Ensure it is securely fastened.
5.2 Instructions de câblage
Figure 4 : Schéma de câblage
Connect the WG-40N in parallel with the main power supply to the protected circuit. The wiring range should be at least 6mm² to ensure proper current handling.
- Connect the Live (L) wire from the main power supply to the 'L Input' terminal on the SPD.
- Connect the Neutral (N) wire from the main power supply to the 'N Input' terminal on the SPD.
- Connect the Protective Earth (PE) wire to the 'Ground' terminal at the bottom of the SPD.
- Assurez-vous que toutes les connexions sont serrées et sécurisées.
- The SPD should be installed downstream of the main circuit breaker or fuse for the protected circuit.
6. Mode d'emploi
Once installed and wired correctly, the Wengart WG-40N operates automatically to protect your electrical system.
6.1 indicateurs d'état
- Fenêtre verte : Indicates that the surge protection module is functioning normally and providing protection.
- Fenêtre rouge : Indicates that the surge protection module has absorbed an overvoltage event and is no longer functional. The module requires replacement.
6.2 Real-Time Protection
Figure 5: Real-Time Protection
The device continuously monitors the electrical system for transient overvoltages. Upon detection, it diverts the excess current safely to the ground, protecting connected equipment. This ensures electrical safety even during thunderstorms.
7. Entretien
The Wengart WG-40N is designed for minimal maintenance, primarily focusing on the replacement of its protection module.
7.1 Remplacement du module
Figure 6: Replaceable Module
When the indicator window turns rouge, it signifies that the internal protection module has reached its end of life due to absorbing a significant surge. To restore full protection, the module must be replaced.
- Débrancher l'alimentation : Ensure the main power supply to the SPD circuit is completely disconnected before attempting replacement.
- Supprimer l'ancien module : Gently pull the faulty module upwards and outwards from its housing. It is designed to be easily detachable.
- Insérer un nouveau module : Align the new replacement module with the slot and push it firmly into place until it clicks.
- Restaurer l'alimentation : Reconnect the main power supply. The indicator window on the new module should display vert.
8. Dépannage
- Indicator Window is Red: This indicates the protection module has failed and needs to be replaced. Follow the module replacement instructions in Section 7.1.
- No Power to Protected Devices: Check the main circuit breaker or fuse for the protected circuit. Ensure all wiring connections to the SPD are secure. If the issue persists, consult a qualified electrician.
- Frequent Module Failure: If modules fail frequently, it may indicate a persistent overvoltage issue or inadequate grounding. Consult a qualified electrician to assess your electrical system.
