GN-RJ45-1000M RJ45 Signal Surge Protective Device for Gigabit Ethernet, 5 kA Imax

Description

The GN-RJ45-1000M is a signal surge protective device for network equipment that transmits over Category 5 or higher cabling. It is installed on the line side in front of the equipment to be protected, and it uses an RJ45 interface with protection applied to all 8 wires (Pin1–Pin8).

Product Overview

The GN-RJ45-1000M is intended for overvoltage protection of network equipment on transmission lines using Category 5 or higher cable. Typical equipment includes computer network servers, routers, hubs, network switches, and broadband equipment. The device is installed directly in front of the protected equipment or system, and the closer it is to that equipment, the better.

Applications

The GN-RJ45-1000M is used on network transmission lines built with Category 5 or higher cable. It is suitable for computer network servers, routers, hubs, network switches, and broadband equipment.

Installation and Use

Before installation, inspect the surge protective device. If it shows any defect, it must not be installed. The device may only be used under the conditions stated in its technical data; exceeding the given upper limits may damage the surge protective device itself and possibly the equipment being protected.

Installation must follow the relevant standards and specifications for the protective device. The device must be installed by qualified professional personnel in front of the electronic equipment that requires protection.

The GN-RJ45-1000M is installed directly at the front end of the protected equipment or system, and it should be placed as close as possible to that equipment. The “IN” terminal connects to the incoming line, and the “OUT” terminal connects to the protected equipment or system. The two line sections must be routed separately and must not be bundled together, to prevent secondary induction.

When installed within the specified conditions, the signal surge protective device does not require long-term maintenance; only routine system maintenance is needed. If a signal transmission problem occurs during use and normal transmission returns after the surge protective device is replaced, the device has been damaged and must be repaired or replaced.

Frequently Asked Questions

What is the difference between the IN and OUT terminals?

“IN” is the incoming line terminal, and “OUT” connects to the protected equipment or system. The two line sections must be routed separately and must not be bundled together.

How close should the device be to the protected equipment?

Install it directly at the front end of the protected equipment or system, as close as possible to that equipment.

How can I tell whether the device has been damaged?

If signal transmission problems occur and normal transmission returns after the surge protective device is replaced, the device has been damaged and must be repaired or replaced.
