34 System grounding
Non-isolated ground topology
In a non isolated system the AC equipment ground (ACEG) connects to the
metal panel, and the associated conduit may also contact various structural
metal. This ground alone is not adequate for the SL-1 system. A true SPG
system will not be possible, but a dedicated ground conductor which connects
to the main building ground is then used for the main ground window to
terminate logic returns and reference the (+) battery bus.
