Starter to Motor (Remote-
Mounted Starters Only)
Ground Wire Terminal Lugs
Ground wire lugs are provided in
the motor terminal box and in
the starter panel.
Terminal Clamps
Terminal clamps are supplied
with the motor terminals to
accommodate either bus bars or
standard motor terminal wire
lugs. Terminal clamps provide
additional surface area to
minimize the possibility of
improper electrical connections.
Wire Terminal Lugs
Wire terminal lugs must be field-
supplied.
1. Use field-provided crimp-type
wire terminal lugs properly
sized for the application.
Note: Wire size ranges for the
starter line and load-side lugs
are listed on the starter
submittal drawings supplied
by the starter manufacturer or
Trane. Carefully review the
submitted wire lug sizes for
compatibility with the
conductor sizes specified by
the electrical engineer or
contractor.

2. A terminal clamp with a 3/8"
bolt is provided on each
motor terminal stud; use the
factor-supplied Belleville
washers on the wire lug
connections.
Figure 18 illustrates the
juncture between a motor
terminal stud and terminal
clamp.
3. Tighten each bolt to 24 foot-
pounds.
4. Install but do not connect the
power leads between the
starter and compressor motor.
(These connections will be
completed under supervision
of a qualified Trane service
engineer after the prestart
inspection).
CAUTION
Correct motor wire
terminations!
Ensure the power supply wiring
and output motor wiring are
connected to the proper
terminals. Failure to do so will
cause catastrophic failure of the
starter and, or the motor.
Bus Bars
Install bus bars between the
motor terminals when a low-
voltage "across-the-line,"
"primary reactor/resistor," "auto
transformer," customer-supplied
solid-state starter, or customer-
supplied AFD are field applied.
Be sure to bus motor terminal T1
to T6, T2 to T4, and T3 to T5.
Note: Bus bars are not needed in
high-voltage applications since
only 3 terminals are used in the
motor and starter.
Starter to UCP (Remote-
Mounted Starters Only)
Electrical connections required
between the remote-mounted
starter and the unit control panel
are shown in an example of a
point-to-point starter-to-UCP
connection diagram as shown at
the end of the manual.
Note: Install control voltage
conduit into control voltage
section of chiller control panel
and starter panel. Do not route
with low voltage (30 volts)
conduit wires.
When sizing and installing the
electrical conductors for these
circuits, follow the guidelines
listed.
Unless otherwise specified use
14 ga. wire for 120 V control
circuits.
