2.3.2 Wire Routing for Power & Non-Power Limited
All wiring entry points are designated on the diagram by arrows. All circuits are classified UL installation power limited
except for the battery leads which are not power limited.
A minimum ¼" (6.4mm) separation must be maintained at all points between power limited and non-power limited wiring
and connections. See "Wiring Diagrams" on page 241 for expanded diagrams.
Note: Wire entry for power limited wiring must be separated by a different entry access from non-power limited wiring.
