Important Notice.
The console has two earth posts on the rear connector panel. They are located
near to the power supply connectors. The un-insulated metal post is the chassis
ground, and the insulated post is the system ground. The console is supplied with
these two posts linked together. It is essential that the console is operated with
these two earths linked. They may, however, be linked at a different point in the
installation: for example, a technical earth in the installation site. In this case the
wire link between the two posts must be removed.

The ANCILLARY METERS D-type connector carries the Groups and Auxes into
the meterbridge. The actual connections used will depend on the number of ancil-
lary meters which are fitted. The connections are:
