General Electrical Recommendations
Electrical Parts
When reviewing this manual keep in mind.
• All field-installed wiring must be in accordance with
local regulations, CE directives and guidelines. Be sure
to satisfy proper equipment grounding requirements
according CE
• The following standardized values - Maximum Amps -
Short Circuit Amps - Starting Amps are displayed on unit
nameplate.
• All field-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 specific 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 with Capacitor!
Disconnect all electric power, including remote disconnects
and discharge all motor start/run and AFD (Adaptive
Frequency™ 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 five (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 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.
Note:
prior to servicing the centrifugal compressor, please
read carefully the service documents for this compressor
that are shipped with the unit.
Do not operate compressor without box cover in place.
Failure to follow all electrical safety precautions could result
in death or seriously injure.
CAUTION!
To avoid corrosion, overheating or general
damage, at terminal connections, unit is designed for
copper mono-conductors only. In case of multiconductor
cable, an intermediate connection box must be added.
For cable with alternative material, bi-material connecting
devices are mandatory. Cable routing inside control panel
should be made case by case by installer.
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:
TNS
IT
TNC
TT
Standard
Special
Special
Standard*
* Differential protection should be suited for industrial
machinery with current leak which can be higher than 500
mA (several motors and frequency drives).
