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.
