EARU EASPD-E AC Surge Protective Device Instruction Manual

1. Bubuka

The EARU EASPD-E AC Surge Protective Device (SPD) is designed to safeguard electrical systems and connected equipment from transient over-voltages caused by lightning strikes and other electrical surges. This device is suitable for single-phase power distribution and control systems operating at AC50/60Hz, 230V, with available variants for 275V and 385V applications. It complies with IEC/EN 61643-1 standards for surge protective devices.

2. Spésifikasi

The EASPD-E series offers robust protection with the following technical parameters:

3. Pamasangan

WARNING: The circuit is dangerous. Installation must be performed by a professional electrician.

The surge protector is designed for direct connection to the home's main electrical panel, typically after the main air switch or leakage protection device. It should be connected in parallel with the main circuit, ensuring proper grounding.

3.1 Pamasangan

The EASPD-E device is designed for 35mm DIN rail mounting. Ensure the DIN rail is securely installed within the electrical enclosure.

3.2 Parentah Wiring

Connect the surge protector directly to the main electrical lines (Live and Neutral) and ensure a robust grounding connection. The grounding wire is crucial for effective surge protection.

The diagrams illustrate two common wiring configurations:

• Top Diagram: Shows connection with a main circuit breaker and a leakage protection device. The surge protector is connected in parallel to the Live (L) and Neutral (N) lines, with the N-PE module connected to the ground.
• Bottom Diagram: Shows connection with a main circuit breaker and a residual current device (RCD). Similar parallel connection to L and N, with the N-PE module grounded.

Ensure all connections are tight and secure. Verify the correct polarity for Live (L) and Neutral (N) inputs.

4. Operasi

The EASPD-E surge protector operates automatically to divert transient over-voltages to the ground, protecting your electrical system. It features a visual warning module to indicate its operational status.

4.1 Visual Indicator

Each protective module is equipped with a visual indicator window:

• héjo: Indicates normal working condition. The surge protector is functioning correctly.
• Beureum: Indicates a working state failure. The lightning protection module has failed and needs to be replaced.

Regularly check the indicator windows to ensure continuous protection.

4.2 Desain Modular

The EASPD-E features a modular design, allowing for easy replacement of individual protective cartridges without needing to replace the entire device. This is demonstrated in the video below.

This video shows how to safely remove and insert the protective modules, highlighting the ease of maintenance.

5. Pangropéa

The EASPD-E surge protector requires minimal maintenance. The primary maintenance task involves monitoring the visual indicator and replacing failed modules.

5.1 Ngaganti modul

If the visual indicator turns beureum, it signifies that the internal protection component has been compromised and the module needs to be replaced. To replace a module:

1. Pastikeun Kaamanan: Turn off the main power supply to the electrical panel before attempting any module replacement.
2. Remove Failed Module: Gently pull the red-indicated module upwards and outwards from its base.
3. Selapkeun Modul Anyar: Align the new module with the slots in the base and push it firmly downwards until it clicks into place.
4. Mulangkeun Daya: Once the new module is securely installed, restore power to the electrical panel. The indicator should now be hejo.

Always ensure power is off before handling electrical components. If unsure, consult a professional electrician.

6. Cara ngungkulan

6.1 Indicator is Red

Masalah: The visual indicator window on one or more modules is red.

Cukang lantaranana: The surge protective module has absorbed a significant surge event or has reached its end-of-life due to multiple smaller surges, indicating failure.

Solusi: Replace the failed module(s) as described in the "5.1 Module Replacement" section. If the indicator remains red after replacement, or if the issue persists, consult a professional electrician.

6.2 No Power After Installation

Masalah: No power to the protected circuit after installing the SPD.

Cukang lantaranana: Incorrect wiring, loose connections, or a tripped circuit breaker/RCD.

Solusi:

1. Pareuman kakuatan utama.
2. Carefully re-check all wiring connections against the diagrams in "3.2 Wiring Instructions".
3. Ensure all terminals are tightened securely.
4. Check if any circuit breakers or RCDs have tripped and reset them if necessary.
5. If the problem persists, seek assistance from a qualified electrician.

7. Tips pamaké

• Pamasangan profésional: Due to the inherent dangers of working with electrical circuits, it is highly recommended that installation and any module replacements be carried out by a qualified and professional electrician.
• Kasaluyuan Sistim: Sateuacan meuliasing or installing, verify that the surge protector's specifications (e.g., voltage, number of poles) are compatible with your specific electrical system (e.g., single-phase, three-phase, 3-wire, 4-wire). If you are unsure about compatibility, especially for complex systems like a 3-phase system used for a single-phase 3-wire setup, consult an electrician.
• Cék biasa: Periodically inspect the visual indicators on your surge protector modules to ensure they are green, indicating normal operation.
• Grounding anu leres: The effectiveness of any surge protective device heavily relies on a proper and robust grounding system. Ensure your electrical installation has an adequate ground connection.
