Connecting the Power
Introduction After connecting the devices to the switch, connect the power cable.
There are certain practical and safety considerations to be made be-
fore powering the switch on.
The Power Cable
Ground warning The switch is delivered with a power cable that fits the power sockets
in your country. If this is not the case, contact your dealer immediate-
ly and ask for the correct power cable.
Power cable wiring color
code
The wires in the power cable provided are color coded:
Important for UK use If the colors of the wires in the power cable provided do not corre-
spond with the markings that identify the terminals in your plug:
1 Make sure that the green and yellow wire is connected to the
terminal marked with the letter E, or with the ground symbol
, or is colored green and yellow.
2 Make sure that the blue wire is connected to the terminal
marked with the letter N or colored black.
3 Make sure that the brown wire is connected to the terminal
marked with the letter L or colored red.
Power supply to a rack If the switch is installed in a rack, make sure the rack’s power supply
socket has a ground connection and the rack is connected to a branch
supply or a power supply socket with a ground connection.
To avoid overloading the circuit and damaging the wiring of the pow-
er supply, the power supply to the rack must be adequate to cover the
extra power consumed by the switch.
