# Lightning Protection Recommendation

All outdoor electronic equipment is susceptible to lightning damage. Proper grounding to national and local codes is instrumental in providing human safety. Lightning Protection is used to maximize the reliability of the electronic system by diverting the excess energy that can be induced on any transmission lines (data, power) through a series of surge protection devices. The energy is dissipated through heat and also diverted to ground.

## What Protection is Provided?

All Tsunami QuickBridge radio units have built-in lightning protection on both the power supply lines and the Ethernet lines. There are TVS diodes that provide protection to IEC 61000-4-05. Proxim Corporation uses “well-design” practices incorporating these devices in the Tsunami QuickBridge products.

## Why is Additional Protection Recommended?

Lightning, even with the built-in protection, can still damage outdoor Tsunami equipment. This can occur for any number of reasons, such as an improperly grounded installation, or when the amount of transient energy from nearby lightning exceeds what the devices can handle.

If a Tsunami unit fails due to damage from lightning, the link is out-of-service until the unit is replaced or repaired. An external, revertive protection device can provide a higher level of protection and greater probability of surviving lightning transients without damage to the Tsunami equipment. If damage does occur, most likely it is to the lightning protection devices and not the Tsunami equipment. Remember, even with external lightening protection, damage can still occur to the Tsunami outdoor units.

## What Protection is Recommended?

Proxim recommends the following for its QuickBridge products:

### PolyPhaser CAT 5 Data Protector

This is a heavy-duty aluminum, weather-tight enclosure for outdoor use that serves to protect wireless outdoor units, as well as the indoor power & Ethernet adapter and connected line equipment inside the roof penetration. This product can be used for all CAT 5 cable lengths up to 100 meters from the outdoor wireless unit to the indoor power & Ethernet adapter.

The Polyphaser Data Protector uses Cascade Technology. This is a multi-stage technology that is superior to single stage because of high surge current capacity and fast response time. The unit is designed to fit in-line onto the outdoor CAT 5e cable, using two weatherized plug openings for the cable to enter and exit. The existing cable is cut, dressed, and reconnected onto two sets of 8 screw terminals inside the Data Protector.

### Transtector Systems Surge Supressor

This outdoor-use, molded plastic, weather-tight enclosure is a surge suppressor designed to protect the QuickBridge II unit from lightning damage. This product can be used for CAT 5 cable lengths up to 50 meters from the outdoor wireless unit to indoor power & Ethernet adapter.

The 1101-TSU uses silicon avalanche suppression diodes (SASD) to provide lower voltage protection level (VPL). This technology provides a superior protection level over traditional gas tube type devices. The unit is designed to fit onto a CAT 5 cable in a pass-through configuration. The input and output connections can be made at two sets of 8-screw terminals, or two 8-pin DIN style connectors. This arrangement allows the installation of the connectorized CAT 5e cable directly into the Surge Suppressor, or with a cut cable.

## How are the Lightning Protection Units Connected to the CAT 5 Cable?

The lightning protection units recommended are designed to be installed in-line onto the CAT 5e cable that connects the outdoor QuickBridge unit to the indoor power adapter.

The lightning protection device has a Surge (cable-facing) side, and an Equipment (equipment-facing) side. The Equipment side faces the outdoor QuickBridge unit or the indoor power & Ethernet adapter. The Surge side faces the long length of cable; when installing two lightning protection units, each unit’s Surge side face one another.

See pin-out information for each unit in “Protection Unit Specifications” for connecting the cable to the protection device.

## Where Should the Protection Units be Located?

At least one unit should be installed near every outdoor QuickBridge unit. General guidelines are:

- Locate protector as close to the outdoor QuickBridge unit as possible, where the lightning protection unit can be securely mounted to a flat surface and grounded properly. Ideally, this should be no further than five feet away from the unit.

- Locate one protector at the roof penetration point, outside, so that the cable immediately enters the building after the protection unit. This protector is optional if the distance from the first unit to the roof penetration point is relatively short (under 15 feet).

Installing two protectors provides the maximum protection against lightning damage to the outdoor QuickBridge II unit and the indoor power & Ethernet adapter, especially if the CAT 5 cable length is greater than 15 meters.

The QuickBridge contains two complete radio units. A total of two or four lightning protection units should be ordered per QuickBridge link.
