About Wiring Drawings
The typical Duplex customer
connection diagrams shown at the
end of this manual are
representative of standard CDHF
units, and are provided only for
general reference. Because these
illustrations may not reflect the
actual wiring of your unit always
refer to the wiring diagrams that
shipped with the chiller for specific
electrical schematic and connection
information.
Note:
Unit-mounted starters are
available as an option on CDHF
units.
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.
As you review this manual, along
with the wiring instructions
presented in this section, keep in
mind that:
1. Typical field connection
requirements for remote-mounted
starters are shown in drawings at
end of the manual and
summarized in Table below.
2. All field-installed wiring must
conform to NEC guidelines, as
well as to any applicable state and
local codes. Be sure to satisfy
proper equipment grounding
requirements per NEC.
3. Compressor motor electrical data
including motor kw, voltage
utilization range, rated load amps
and locked rotor amps is listed on
the chiller nameplate.
4. All field-installed wiring should be
checked for proper terminations,
and for possible shorts or
grounds.
General Requirements
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.
Note: For additional information
regarding the safe discharge of
capacitors, see PROD-SVB06A-EN or
PROD-SVB06A-FR.
