CVHE-SVN03D-EN 4
General
Information
General
Requirements
Note: Unit-mounted starters are
available as an option on most
CVHE, CVHF, and CVHG units with
wye delta, and solid-state starters,
with nominal voltages of up to 600
volts and unit mounted medium
voltage across-the-line starters.
While this option eliminates most
field-installed wiring requirements,
the electrical contractor must still
complete the electrical connection
for: (1) Power supply wiring to the
starter, (2) Other unit control options
present, and (3) Any field-supplied
control devices.
 WARNING!
Hazardous Voltage w/
Capacitors!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power cannot be inadvertently
energized. For variable frequency
drives or other energy storing
components provided by Trane or
others, refer to the appropriate
manufacturer’s literature for
allowable waiting periods for
discharge of capacitors. Verify with
an appropriate voltmeter that all
capacitors have discharged. Failure
to disconnect power and discharge
capacitors before servicing could
result in death or serious injury.
 WARNING
Rotating Parts!
During installation, testing,
servicing and troubleshooting of
this product it may be necessary to
measure the speed of rotating
components. Have a qualified or
licensed service individual who has
been properly trained in handling
exposed rotating components
perform these tasks. Failure to
follow all safety precautions when
exposed to rotating components
could result in death or serious
injury.
As you review this manual, along
with the wiring instructions
presented in this section, keep in
mind that:
Typical field connection
requirements for remote-mounted
starters are shown at the end of the
manual, and summarized in Table 1.
All field-installed wiring must
conform to National Electric Code
(NEC) guidelines, as well as to any
applicable state and local codes. Be
sure to satisfy proper equipment
grounding requirements per NEC.
All field-installed wiring must be
checked for proper terminations, and
for possible shorts or grounds.
Note: The typical customer
connection diagrams shown in this
manual are representative of
standard CVHE, CVHF and CVHG
units, and are provided only for
general reference. Always refer to
the actual wiring diagrams that
shipped with the chiller for specific
as built electrical schematic and
connection information.
Do not modify or cut enclosure to
provide electrical access. Removable
panels have been provided for this
purpose. Modify these panels only;
away from enclosure. Refer to
installation information shipped
with the starter or submittal
drawings.
CAUTION
Component Damage!
Remove all debris from inside the
starter panel. Failure to do so may
result in an electrical short and
could cause serious starter
component damage.
