I. Product Introduction:
OrdENThe surge protection module is designed, manufactured, and tested in accordance with international standards IEC61643, national standards GB18802.1, as well as meteorological industry standards QX10.1-2002 and communication industry standards YD/T1235.1-2002. The product is strictly controlled under the ISO9001 quality assurance system.
This product is widely used in power systems for mobile communication base stations, microwave communication offices/stations, telecommunication rooms, industrial factories and mines, civil aviation, etc., such as various power distribution stations, distribution rooms, distribution cabinets, AC/DC distribution boards, switch boxes, and other critical equipment prone to lightning strikes.
◆ Utilizes a pressure-sensitive resistor chip for stable and reliable performance.
◆ Features a plug-and-play structure for easy replacement;
Mechanical thermal release device with high sensitivity.
◆ Modular sealing design, high flow rate, lower protection level;
Single-phase, capable of being combined into multi-pole for use in various grid configurations.
◆ Equipped with a degradation display window, and can be fitted with a remote遥信output interface.
The housing is made of high flame-retardant material, offering high safety performance.
35mm track mounting, standard modular design.
◆ The product is available with an optional FM alarm feature.
◆ A wide variety of colors and styles available to meet various aesthetic requirements!
◆ Product parameters are for single-module units. For three-phase, please change the model to /4. For single-phase, please change the model to /2.

Section 4: Product Installation Instructions:
1. Power must be disconnected before installation, and live operation is strictly prohibited.
2. Recommend installing a fuse or an empty switch in series at the front of the lightning protection module.
3. SPD is parallel installed at the power input end of the building's distribution box or the power room. The product is for rail-mounted installation, and the Kelvin connection method can be adopted under favorable conditions.
4. Please connect according to the installation diagram provided: L for live wire, N for neutral wire, and PE for ground wire. Do not connect incorrectly. After installation, close the circuit breaker switch and check if the operating status is normal.
5. During operation, the lightning protection module should be regularly inspected and the status of the fault display window checked. If the fault display window shows red or the remote signal terminal outputs an alarm signal, it indicates a fault in the lightning protection module, and it should be repaired or replaced promptly.
6. Suitable for indoor operation; if installed outdoors, a waterproof housing must be added.
All connections must be firm and reliable electrical connections.
8. Lightning protection grounding must comply with lightning protection standards, with grounding wires as thick and short as possible, and the grounding resistance should be less than 10Ω.
