Unit-mounted starters are available as an option on
most units. While this option eliminates most field-
installed wiring requirements, the electrical contractor
must still complete the electrical connection for the
following:
•
power supply wiring to the starter
•
other unit control options present
•
any field-supplied control devices
As you review this manual along with the wiring
instructions presented in this section, keep in mind
that:
•
All field-installed wiring must conform to National
Electric Code (NEC) guidelines, and any applicable
local, state, and national 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, and locked rotor amps) is listed on
the chiller nameplate.
•
All field-installed wiring must be checked for proper
terminations, and for possible shorts or grounds.
N
No
otte
e:: Always refer to the actual wiring diagrams
that shipped with the chiller or the unit
submittal for specific as-built electrical
schematic and connection information.

Do NOT modify or cut enclosure to provide electrical
access. Removable panels have been provided, and
any modification should be done away from the
enclosure. If the starter enclosure must be cut to
provide electrical access, exercise care to prevent
debris from falling inside the enclosure. Refer to
installation information shipped with the starter or
submittal drawings.
Electrical Requirements
Before wiring begins, observe the following electrical
requirements:
•
Follow all lockout/tagout procedures prior to
performing installation and/or service on the unit.
•
Always wear appropriate personal protective
equipment.
•
Wait the required time to allow the capacitor(s) to
discharge; this could be up to 30 minutes.
•
Verify that all capacitors are discharged prior to
service using a properly rated volt meter.
•
Use appropriate capacitor discharge tool when
necessary.
•
Comply with the safety practices recommended in
PROD-SVB06*-EN.
