IN ANNEX B.

The terminal marked at the rear panel is a Technical Earth. Its use is

recommended. This is NOT a protective earth for electric shock protection.

The terminal is provided to:
1. Ensure all equipment chassis fixed within a rack are at the same

technical earth potential. To do this, connect a wire between the

Technical Earth terminal and a suitable point on the rack

2. Eliminate the migration of stray charges when connecting between

equipment.

The Technical Earth provides a suitable connection between the IRD and

the installation to give a low impedance path at normal operating

frequencies.
