3.2.10 Lightning Protection/Out-of-Building Connections
The following are the only supported scenarios in which wired extensions and devices outside the main building can be
connected to the IP Office system. In these scenarios, additional protection, in the form of protective grounding and
surge protectors, must be fitted.
·
The fitting of additional protection does not remove the risk of damage. It merely reduces the chances of damage.
Cabling Requirements
·
Cables of different types, for example trunk lines, extensions, ground and power connections, should be kept separate.
·
All cabling between building should be enclosed in grounded ducting. Ideally this ducting should be buried.
·
A Primary Protection Box must be provided at the point where the cables enter the building. This should be three point
protection (tip, ring and ground). Typically this would be gas tube protection provided by the local telephone company.
The ground wire must be thick enough to handle all the lines being affected by indirect strike at the same time.

3.3 Install Overview
Essential Edition - PARTNER® Version is an out of the box installation and is meant to work correctly when it is switched
on, without requiring any setting up or pre configuration. The efficiency of this automatic procedure is simplified and
guaranteed by following a few basic rules in connecting up cable groups and populating the card slots of the control unit
as follows:
·
Insert base cards working from left to right and do not leave unoccupied slots between cards.
·
Apply simple housekeeping rules to cables by tying them in associated and clearly labeled bundles.
·
Route cables carefully so that they do not intrude the working area or create a hazard
