Power the transformer primary through a dedicated circuit. If the primary has
a pluggable cord, make an additional ground connection between the
Option 11C Mini SPG and a known building ground reference. This
connection is very important for safe and reliable operation.
CAUTION
Do not connect any system ground lines of the Option 11C Mini to
structural steel or water pipes, or other unreliable ground paths. Use a
ground point known to be “clean” and permanent. Place a “DO NOT
DISCONNECT” tag on it. Figure 7 on page 61 shows the pluggable
cord connections.
