Starter to Motor Wiring (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
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as the equipment was not
designed or qualified to accept other types of
conductors.
Note: Graphic labels (shown above) are used for CE
application only.
Important:
• Before servicing, disconnect all power
sources and allow at least 30 minutes for
capacitors to discharge.
• All electrical enclosures—unit or remote—
are IP2X.
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
NOTICE
Component Damage!
Failure to ensure the power supply wiring and output
to motor wiring are connected to the proper terminals
could cause catastrophic failure of the starter and/or
motor.
Wire terminal lugs must be field supplied.
• 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.
• On 600V and below, a terminal clamp with a
3/8-in. (9.525-mm) bolt is provided on each motor
terminal stud; use the factory-supplied Belleville
washers on the wire lug connections. The following
figure illustrates the junction between a motor terminal
stud and terminal lug.
• Torque for this assembly is 24 ft·lb (32.5 N·m).
• 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 pre-start inspection.)
