AC Power and Earthing Requirements

The CTX100 requires an earth connection back to the main distribution point for proper operation and
safety. Failure to provide this earth may be a safety hazzard or lead to confusing fault, or operational
symptoms and,in extreme cases, system failure. The AC power cord already contains a conductor for
the "protective earth" provided by the commercial power outlet. This alone is not sufficient. It is also
necessary to connect a seperate insulated conductor between the Frame Ground (FG) terminal on the
base KSU and the main distribution point. (See
the general rules for earthing contained in BS6701 parts 1 & 2.
Note Please note, no plug is fitted to the European version of CTX100 Product. Please refer to
the chapter 'Notes to Users' at the end of this manual, which defines the power
connection method.
