Proxim CPN 65756B manual Cable System, Placement of the Surge Arrestor

Tsunami MP.11a Antenna Installation Guide

▪The location provides a connection to the network backbone (an Ethernet LAN cable that is connected to a hub, bridge, or directly into a patch panel)

▪The location is as close as possible to the point where the antenna cable will enter the building (see “Placement of the Surge Arrestor” below).

▪The ideal location has a temperature of 0-55 degrees Celsius and a maximum relative humidity (non- condensing) of 95%.

CAUTION!	The Tsunami MP.11a hardware, the surge arrestor, and the antenna mast must be connected to
	the same grounding system.

Cable System

CAUTION!	The Tsunami MP.11a products are designed for indoor installation. At all times the location of the
	Tsunami MP.11a radio unit and power supply must be indoors, to protect the unit from extreme
	weather conditions, excessive heat and humidity, and to keep the unit free from vibration and
	dust. The antenna and surge arrestor can be placed outdoors.

Prior to mounting the Tsunami MP.11a, you are advised to calculate carefully:

▪The distance between the intended location of your Tsunami MP.11a hardware and the location of the antenna mast

▪The height of the antenna on the mast.

If the low-loss antenna cable is not long enough to cover this distance you can select another:

▪Cable length from the Proxim Systems low-loss cable offering

▪Location that satisfies the requirements listed previously to mount your Tsunami MP.11a hardware

As the length of the antenna cable may affect the actual range of your outdoor antenna installation, the last option is preferred.

WARNING!	You must not change the length of the low-loss antenna cable to a length shorter than allowed by
	the radio’s certifications (see “Appendix C. Certified Outdoor Solutions “on page 48. Shortening
	the cable will void the Proxim Corporation warranty and may conflict with radio certifications or
	approvals.

How to install the Tsunami MP.11a hardware is described in Tsunami MP.11a Installation and Management, which comes on the Tsunami MP.11a product CD.

Placement of the Surge Arrestor

The surge arrestor is an indispensable part of your outdoor antenna installation. It protects your sensitive electronic equipment from transients or electro-static discharges at the antenna.

For optimal protection, the surge arrestor must be installed at a location that satisfies the following requirements:

▪A location as close to the location where the antenna cable will enter the building (see “Placement of the Tsunami MP.11a Hardware” on page 9).
