1. THIS UNIT MUST BE CORRECTLY EARTHED THROUGH THE MOULDED PLUG SUPPLIED.

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 equipment and the
installation to give a low impedance path at normal operating frequencies.
