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 unit
package 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 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 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 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.
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 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 Standard** Special Standard*
* Differential protection should be suited for industrial ma-
chinery with current leak which can be higher than 500 mA
(several motors and frequency drives).
** Filter RFI disconnect on VPF and EC fan.
Electrical data
To get the following electrical data details: Refer to
General Data tables for each unit configuration and size.
− Maximum Power input (kW)
− Unit rated amps (Max comp + Fan + Control)
− Unit start up amps (Starting Amps of the largest
comp + RLA of 2nd comp + RLA of all fans+
control)
− Compressor Power factor
− Disconnect switch size (A)
− Short Circuit Rating for all sizes =15 kA
Wiring diagrams are shipped with unit and can be found
in the unit control panel.
Note: Rating is made for 400 V, 3 phases, 50 Hz power
supply.
