COMMUNICATION PORT SURGE PROTECTION    


The ZapTech RJ series protection devices were specifically designed to protect communication interfaces from damage caused by lightning storms, static discharge, secondary effects of power surges and transient ground potential energies.

As a significant measure to prevent electrical damage to your system, surge suppression also extends the life of sensitive circuits at the component level while improving system reliability. Zap-Tech protectors are best applied as near as physically practical to sensitive electronic equipment, components and system ground references. RJ series devices are specifically configured for installation directly onto the communication port on your equipment. The devices provide protection for Modular RJ11 and RJ45 interfaces to protect RS422, RS485, RS232, Ethernet, T-1, DDS and most other applications using Modular RJ11 and RJ45 interface connectors. It is essential that one protector be installed at each end of a long communication cable.

The RJ series grounding wire must be connected to earth Ideally, via the chassis ground of the protected equipment. It is important that the equipment chassis is properly grounded to electrical safety ground via a standard 3-prong power cord.

OPERATION:  
The Zap-Tech protector will repetitively protect and reset without
degradation up to it's maximum repetitive self-reset surge. If it is 
subjected to more than it's maximum repetitive self-reset surge, the  
device will remain in a clamped mode indicating that it should be removed 
or replaced while keeping  the equipment safe from subsequent surges.

INSTALLATION:
Zap-Tech protectors should be installed in series with the incoming
communication line at the port of the equipment being protected. The
protector's grounding wire must be connected to the chassis ground 
of the protected equipment.

IMPORTANT!
It is important that the protector and the chassis of the equipment to be
protected are both properly grounded to a properly earthed electrical 
safety ground via the equipment's 3-prong power cord and/or a ground
wire of 14 AWG or larger. Protectors should be installed at both ends of
communication lines to ensure equipment protection at each end.
