• 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 must be field supplied.
• Use field-provided, crimp-type wire terminal lugs
properly sized for the application.
N No otte e:: 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.)
