3.2.4 Earthing
Each panel is separately connected to the ac power distribution system
’
s earth though the appliance
coupler
’
s green/yellow wire connection. All exposed panel metalwork (main frame and doors) is also
connected to this earth.
If the framework is earthed only through each panel (i.e. through the panel
’
s mounting bolts), there is
a possibility of electrical damage if a wiring fault occurs, or if an electrical discharge, such as lightning
strike, hits the panels. Under these circumstances, the current discharge path will be through the panel
to earth rather than through the framework to earth. When permanently installed on a metal
framework, the framework itself should be directly connected to earth.

3.3 Power Cable Wiring
3.3.1 AC Power
An approved three-pole appliance coupler inside the center door connects to the AC supply. The AC
power cable is then connected to the EMI filter and distributes to the power supply units on left and
right doors. Each door has an earth point for grounding.
DC power from each power supply unit provides low voltage power to the assigned electronics
components, for example, driver board, and fans, the responding color of the wire represents the
relevant component´s power connection, please note the list below for a clear cabling configuration.
