Technical Earth
The Technical Earth provides a suitable connection between the equipment and the installation to give a low impedance path at
normal operating frequencies.
The terminal is provided to:
1.
Ensure all equipment chassis fixed within a rack are at the same technical earth potential.
2.
Eliminate the migration of stray charges when connecting between equipment.
To do this, connect a wire between the Technical Earth terminal and a suitable point on the rack.
CAUTION!
It is strongly recommended that the earth terminal at the rear panel of the equipment is connected to a site Technical Earth before
any external connections are made and the equipment is powered. This limits the migration of stray charges.
Lightning Protection
WARNING!
If the equipment has been subject to a lightening strike or power surge, which has stopped it working, disconnect the power
immediately, do not re-apply power until it has been checked for safety. If in doubt, contact Customer Services.
Where appropriate, ensure this product has an adequate level of lightning protection. Alternatively, during a lightning storm or when
it is left unattended and unused for long periods of time, unplug it from the supply outlet and disconnect the output equipment. This
prevents damage to the product due to lightning and power line surges.
