General Electrical Recommendations
Electrical Parts
When reviewing this manual keep in mind.
• All fi eld-installed wiring must be in accordance with
local regulations and CE directives and guidelines. Be
sure to satisfy proper equipment grounding requirements
according CE
• Compressor motor and unit electrical data (including
motor kW, voltage utilization range, rated load amps) is
listed on the chiller nameplate
• All fi eld-installed wiring must be checked for proper
terminations, and for possible shorts or grounds
Note: always refer to wiring diagrams shipped with chiller
or unit submittal for specifi c electrical schematic and
connection information.
Important: to prevent control malfunctions, do not run
low voltage wiring (<30V) in conduit with conductors
carrying more than 30 volts.
WARNING! Hazardous Voltage w/Capacitor!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run and
AFD (Adaptive Frequency TM Drive) capacitors 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 discharges capacitors. Verify with an
appropriate voltmeter that all capacitors have discharged
• DC bus capacitors retain hazardous voltages after input
power has been disconnected. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized
After disconnecting input power, wait fi ve (5) minutes for
units which are equipped with EC fans and wait twenty
(20) minutes for units which are equipped with variable
frequency drive (0V DC) before touching any internal
components.
Failure to follow these instructions could result death or
serious injury
For additional information regarding the safe discharge
of capacitors, see “Adaptive Frequency™ Drive (AFD3)
Capacitor Discharge” and BAS-SVX19B-E4.
Hazardous Voltage – Pressurized Burning Fluid!
Before removing compressor terminal box cover for
servicing, or servicing power side of control panel,
CLOSE COMPRESSOR DISCHARGE SERVICE VALVE
and disconnect all electric power including remote
disconnects. Discharge all motor start/run capacitors.
Follow lockout/tagout procedures to ensure the power
cannot be inadvertently energized. Verify with an
appropriate voltmeter that all capacitors have discharged.
The compressor contains hot, pressurized refrigerant.
Motor terminals act as a seal against this refrigerant.
Care should be taken when servicing NOT to damage or
loosen motor terminals.
Do not operate compressor without terminal box cover
in place.
Failure to follow all electrical safety precautions could
result in death or seriously injure.
For additional information regarding the safe discharge
of capacitors, see “Adaptive Frequency™ Drive (AFD3)
Capacitor Discharge” and BAS-SVX19B-E4.
CAUTION! To avoid corrosion and overheating at
terminal connections, use copper mono-conductors only.
Failure to do so may result in damage to the equipment.
In case of multiconductor cable, an intermediate
connection box must be added. Do not allow conduit to
interfere with other components, structural members
or equipment. Control voltage (115V) wiring in conduit
must be separate from conduit carrying low voltage
(<30V) wiring. To prevent control malfunctions, do not
run low voltage wiring (<30V) in conduit with conductors
carrying more than 30V.
WARNING!
The Warning Label shown in Figure 19 is displayed on
the equipment and shown on wiring diagrams and
schematics. Strict adherence to these warnings must be
observed. Failure to do so may result in personal injury
or death.
CAUTION! Units must not be linked to the neutral
wiring of the installation. Units are compatible with the
following neutral operating conditions:
