Earth connection
WARNING! THIS APPLIANCE MUST BE EARTHED.
The green and yellow wire of the mains cord must always be connected to an installation
safety earth or ground. The earth is essential for personal safety as well as the correct
installation of the system, and is internally connected to all exposed metal surfaces. Any
rack framework into which this unit may be mounted is assumed to be connected to the
same grounding circuit.
