Interconnecting Wiring

Typical equipment room conduit
layouts with and without unit-
mounted starters are shown in
Figures 15 and 16, respectively.

IMPORTANT

Keep in mind that the
interconnecting wiring between
the starter panel, compressor
and UCP control panel is factory-
installed with unit-mounted
starters but must be field-
installed when a remote-
mounted starter is used.
