Always use a second wrench to backup the assembly and
prevent applying excessive torque to the terminal shaft.
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).
Note: 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.
NOTICE
Adaptive Frequency Drive (AFD)/Starter
Component Damage!
Failure to remove debris from inside the AFD/starter
panel could result in an electrical short and could
cause serious AFD/starter component damage.
Important: 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.
Note: 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 the tables
in “Trane-supplied Starter Wiring,” p. 57 and
“Customer-supplied Remote Starter Wiring,” p. 58)
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.
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.
Important:
• 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.
