•
Before servicing, disconnect all power
sources and allow at least 30 minutes
for capacitors to discharge.
•
All electrical enclosures—unit or remote
—are IP2X.
Three-Phase Power
Review and follow the guidelines in this section to
properly install and connect the power supply wiring to
the starter panel:
•
Verify that the starter nameplate ratings are
compatible with the power supply characteristics
and with the electrical data on the unit nameplate.

•
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.
•
Use copper conductors to connect the three-phase
power supply to the remote- or unit-mounted
starter panel.
•
Flexible conduit connections are recommended to
enhance serviceability and minimize vibration
transmission.
•
Size the power supply wiring in accordance with
National Electric Code (NEC) and local guidelines,
using the RLA value stamped on the chiller
nameplate and transformer load on L1 and L2.
•
Confirm that wire size is compatible with lug size
stated in unit submittal.
•
Make sure that the incoming power wiring is
properly phased; each power supply conduit run to
the starter must carry the correct number of
conductors to ensure equal phase representation.
N
No
otte
e:: Connect L1, L2, and L3 (shown in the
following figure) per starter diagram
provided with chiller.
•
When installing the power supply conduit, ensure
that the position of the conduit does not interfere
with the serviceability of any of the unit
components, or with structural members and
equipment. Ensure that the conduit is long enough
to simplify any servicing that may be necessary in
the future (e.g., starter).
•
Electrical wire torque specifications—follow starter
manufacturer’s torque specifications.
