The unit is supplied with a two meter detachable power supply cable
equipped with the moulded plug suitable for Europe, UK or US.
The wires in the mains cable are coloured in accordance with the wire
colour code shown in Table 3.

Table 3. Supply Cable wiring colours

1.1.1.16 Protective Earth /Technical Earth

The unit has a Technical Earth terminal located at the rear panel. Its
use is recommended. This is not a Protective earth for electrical shock
protection. The terminal is provided to:
1. Ensure all equipment chassis fixed in the rack are at the same

Technical earth potential. To achieve 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.

Warning: If the moulded plug fitted to the mains cable supplied with
this unit is not required, please dispose of it safely. Failure to do this
may endanger life as live ends may be exposed if the removed plug is
inserted into a mains outlet.

Caution: Power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the appliance.

To achieve protection against earth faults in the installation, connected
to the equipment by signal cables etc., the equipment should always be
connected to protective earth. If the mains appliance coupler is
disconnected while signal cables are connected to the equipment, earth
connection should be achieved by connecting earth to the additional
technical earth connection on the rear panel of the unit.

Warning: This unit must be correctly earthed through the moulded
plug supplied. If the local mains supply does not have an earth
conductor do not connect the unit.

Caution: Consult the supply requirements in

Appendix B: Technical Specification prior to connecting the unit to the
supply.
