Starter to Control Panel Wiring
The unit submittal includes the field wiring connection
diagram and the starter-to-control-panel connection
diagram (showing the electrical connections required
between the remote-mounted starter and the control
panel).
NNoottee:: Install separate conduit into the low voltage
(30 volts) section of the control panel.
When sizing and installing the electrical conductors for
these circuits, follow the guidelines listed. Use 14 AWG
for 120V control circuits unless otherwise specified.

IImmppoorrttaanntt:: Maintain at least 6 in. (16 cm) between low-
voltage (less than 30V) and high-voltage
circuits. Failure to do so could result in
electrical noise that may distort the signals
carried by the low-voltage wiring, including
the inter-processor communication (IPC)
wiring.
To wire the starter to the control panel, use these
guidelines:
• If the starter enclosure must be cut to provide
electrical access, exercise care to prevent debris
from falling inside the enclosure. Do NOT cut the
Adaptive Frequency™ Drive (AFD) enclosure.
• Use only shielded, twisted-pair wiring for the inter-
processsor communication (IPC) circuit between
the starter and the control panel on remote-
mounted starters.
NNoottee:: Recommended wire is Beldon Type 8760,
18 AWG for runs up to 1000 ft (304.8 m). The
polarity of the IPC wiring is critical for proper
operation.
• Separate low-voltage (less than 30V; refer to Table
15, p. 54 and Table 16, p. 55) wiring from the 115V
wiring by running each in its own conduit.
• When routing the IPC circuit out of the starter
enclosure, ensure that it is at least 6 in. (16 cm) from
all wires carrying a higher voltage.

IImmppoorrttaanntt::
• The IPC wiring shield should be
grounded on one end only at control
panel end. The other end should be un-
terminated and taped back on the cable
sheath to prevent any contact between
shield and ground.
• Oil Pump Interlock: All starters must
provide an interlock (normally open)
contact with the chiller oil pump
connected to the control panel at
terminals 1A7-2-4 and 1A7-J2-2
(14 AWG) The purpose of this interlock
is to maintain the oil pump signal in the
event that a starter failure, such as
welded contacts, keeps the chiller
motor running after the controller
interrupts the run signal.
