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.
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.

1.1.1.16 Protective Earth /Technical Earth
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.
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.
