General Recommendations
As you review this manual, keep in mind that:
• All field-installed wiring must conform to National
Electric Code (NEC) guidelines, and any applicable
state and local codes. Be sure to satisfy proper
equipment grounding requirements per NEC.
• Compressor motor and unit electrical data (including
motor kW, voltage utilization range, rated load amps) is
listed on the chiller 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.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as the equipment was not
designed or qualified to accept other types of
conductors.
Important: 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 30 volts.
Installer-Supplied Components
Customer wiring interface connections are shown in the
electrical schematics and connection diagrams that are
shipped with the unit. The installer must provide the
following components if not ordered with the unit:
• Power supply wiring (in conduit) for all field-wired
connections.
• All control (interconnecting) wiring (in conduit) for field
supplied devices.
• Fused-disconnect switches or circuit breakers.
• Power factor correction capacitors. See Power Factor
Correction Engineering Bulletin (RLC-PRB023*-EN).
Power Supply Wiring
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
NEC Table 310.15(B)(16); formerly Table 310-16.
All wiring must comply with local codes and the National
Electrical Code. The installing (or electrical) contractor
must provide and install the system interconnecting wiring,
as well as the power supply wiring. It must be properly
sized and equipped with the appropriate fused disconnect
switches.
The type and installation location(s) of the fused
disconnects must comply with all applicable codes.
Knock-outs for wiring are located on the upper left side of
the control panel.The wiring is passed through these
conduits and connected to the terminal blocks, optional
unit-mounted disconnects, or HACR type breakers. Refer
to the following figure.
