Installation Electrical

General Recommendations

As you review this manual, keep in mind that:
• All fi eld-installed wiring must conform to European
guidelines and any applicable local codes. Be sure to
satisfy proper equipment grounding requirements per
European guidelines.
• 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.
WARNING
Proper Field Wiring and Grounding Required!
All fi eld wiring MUST be performed by qualifi ed
personnel. Improperly installed and grounded fi eld
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
fi eld wiring installation and grounding as described in
local electrical codes. Failure to follow code could result
in death or serious injury.
WARNING
Hazardous Voltage w/Capacitors!
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 discharge of 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 the DC capacitors to
discharge, then check the voltage with a voltmeter.
Make sure DC bus capacitors are discharged (0 VDC)
before touching any internal components.
Failure to follow these instructions could result in death
or serious injury.
For additional information regarding the safe discharge
of capacitors, see "Adaptive Frequency™ Drive (AFD 3 ) 3 3
Capacitor Discharge, " p. 28 and PROD-SVB06A-EN.

WARNING
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 serious injury.
For additional information regarding the safe discharge
of capacitors, see "Adaptive Frequency™ Drive (AFD 3 ) 3 3
Capacitor Discharge, " p. 28 and PROD-SVB06A-EN.
NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types
of conductors. Failure to use copper conductors could
result in equipment damage.
Important: : To prevent control malfunctions, do not run
low voltage wiring (<30 V) in conduit with
conductors carrying more than 30 volts.
