overloads register both line and capacitor-supplied
current.

Interconnecting Wiring

Typical equipment room conduit layouts with and
without unit-mounted starters are shown in the
following two figures.
I I m m p p o o r r t t a a n n t t : : The interconnecting wiring between the
starter panel, compressor, and control
panel is factory-installed with unit-mounted
starters. However, when a remote-mounted
starter is used, the interconnecting wiring
must be field-installed.
N N o o t t e e : : Refer to starter submittal drawing for location of
incoming wiring to the starter.

unit control panel (1000 feet [304.8 m]
maximum).

N N o o t t e e : : Must enter the higher than 30 Vdc Class 1 portion
of the until control panel.
7. Lead power wiring
N N o o t t e e : : Refer to the unit field connection diagram for
approximate unit control panel knock out
locations. To prevent damage to the unit control
panel components, do NOT route control conduit
into the top of the box.
