to. The functional ground jack socket on the back of the G150 can be connected by following
the instructions below.

CAUTION:
This functional ground is not a protective ground.
CAUTION:
To connect the functional ground:
1. Use a 3.5mm Jack Plug (not supplied with kit) fitted with a suitable length of #14 AWG
(minimum) solid insulated cable. The sleeve must not be green/yellow.
2. Insert this Jack Plug into the Functional Ground Jack Socket (in the back of the G150 Media
Gateway).
3. Connect, using a fastening that satisfies local regulations, the other end of the #14 AWG
wire to the approved ground, such as building steel or an earthed metal cold water pipe.
Installing a New G150 System
Initial Assembly - Overview
Prior to initial assembly and mounting (shelf/wall mounting or free standing) of your system,
check that:
The required Trunk Interface Modules have been installed and are of the correct country
variant type.
Where structured cabling is to be used it has been installed, conforms to all local
regulations and is clearly labeled.
To start assembling the G150 Media Gateway, do the following:
1. Mount the G150 module in its final location.
2. Run the Lump-in-Line PSU cable back to the switchable mains supply but do not
switch-on or connect the PSU to the G150.
3. Connect the Trunks, using BRI ISDN Cables, to your provider's trunk sockets.
4. Connect the Phone Ports, using Line Cords, to the structured cable sockets or directly to the
appropriate telephone. Note that in default, the lowest port number corresponds to the
lowest extension number (201 by default).
