Grounding
Grounding
Provision is made for both protective ground (earthing) and functional ground (earthing). In addition,
where the installation of telephone and/or other standard (tip/ring) devices in another building is required,
In-Range-Out-Of-Building (IROB) protectors must be fitted (see Out of Building Telephone Installations
).
Protective Ground
A protective ground must be permanently fitted to IP400 Analog Trunk 16 modules (see IP400 Analog
Trunk 16). Connection of this protective ground requires the use of suitable tools and must be
connected at both ends before connection is made to the telecommunications network.
To connect the protective ground:
1. Attached one end of a #14 AWG (minimum) solid insulated cable (sleeve must be green/yellow)
to the Protective Ground Point as shown below. Ensure that the Ground Post securing screw is
fully tightened.
2. Connect, using a fastening that satisfies local regulations, the other end of the wire to the
approved protective ground.
