Specifications

Remote Starter
14 CVHE-SVN03D-EN
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 6 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
pre-start inspection.)
CAUTION
Component Damage!
Ensure the power supply wiring and
output to motor wiring are
connected to the proper terminals.
Failure to do so will cause
catastrophic failure of the starter
and, or motor.
Bus Bars
Install the bus bars between the
motor terminals when a low-voltage
“across-the-line”, “primary reactor/
resistor,” “auto transformer” or
customer-supplied solid-state, or
customer-supplied AFD.
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.
