Wiring
For detailed information on configuring and wiring an
MS/TP Bus, Field Controller (FC) Bus, and Sensor
Actuator (SA) Bus, refer to the MS/TP Communications
Bus Technical Bulletin (LIT-12011034).
FEC Terminal Blocks and Bus Ports
See Figure 3 for terminal block and bus port locations
on the FEC26 extended temperature controller.
Observe the following guidelines when wiring an FEC
controller.
Input and Output Terminal Blocks
All of the fixed input terminal blocks are mounted on
the bottom of the FEC. The output terminal blocks are
mounted on the top of the controller. See Table 1 for
more information.
FC Bus Terminal Block
The FC Bus terminal block is a blue, removable,
4-terminal plug that fits into a board-mounted jack.
Wire the removable FC Bus terminal block plugs on the
FEC, and other field controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 4. See Table 3 for more information.
Note: The Shield terminal (SHLD) on the FC Bus
terminal block is isolated and can be used to connect
the cable shields on the bus (Figure 4).
SA Bus Terminal Block
The SA Bus terminal block is a brown, removable,
4-terminal plug that fits into a board-mounted jack.
Wire the removable SA Bus terminal block plugs on the
FEC and other SA Bus devices in a daisy-chain
configuration using 4-wire twisted, shielded cable as
shown in Figure 5. See Table 3 for more information.
FC Bus Port
The FC Bus port on the front of the FEC is an RJ-12,
6-position modular jack that provides a connection for
the Bluetooth® Wireless Commissioning Converter,
ZigBee™ wireless dongle, or ZFR1811 Wireless Field
Bus Router.
The FC Bus port is connected internally to the FC Bus
terminal block. See Table 3 for more information. The
FC Bus Port pin assignment is shown in (Figure 6).
!
CAUTION: Risk of Electric Shock.
Disconnect the power supply before
making electrical connections to avoid
electric shock.
IMPORTANT: Do not connect supply power to the
controller before finishing wiring and checking all
wiring connections. Short circuits or improperly
connected wires can result in damage to the
controller and void any warranty.
IMPORTANT: Do not exceed the controller
electrical ratings. Exceeding controller electrical
ratings can result in permanent damage to the
controller and void any warranty.
IMPORTANT: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
IMPORTANT: Electrostatic discharge can damage
FEC components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the FEC controller.
Figure 4: FC Bus Terminal Block Wiring
Figure 5: SA Bus Terminal Block Wiring

FEC26 Extended Temperature Field Equipment Controller Installation Instructions6
Sensor Port
The Sensor (SA Bus) port on the bottom of the FEC
(Figure 3) is an RJ-12, 6-position modular jack that
provides a connection for the Wireless Commissioning
Converter, the VAV Balancing Tool, specified network
sensors, or other SA Bus devices with RJ-12 plugs.
A DIS1710 Local Controller Display also can be
connected to the SA Bus port (but only on FEC models
without an integral display and push buttons).
The Sensor port is connected internally to the SA Bus
terminal block. See Table 3 for more information. The
Sensor Port pin assignment is shown in Figure 6.
Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a board-
mounted jack on the top right of the FEC.

FEC Terminal Functions, Ratings,
Requirements, and Wiring Guidelines
Input and Output Wiring Guidelines
Table 1 provides information and guidelines about the
functions, ratings, and requirements for the FEC input
and output terminals, and references guidelines for
determining proper wire sizes and cable lengths.
In addition to the wiring guidelines in Table 1, observe
these guidelines when wiring FEC inputs and outputs:
•Runall low-voltage wiring and cables separate
from high-voltage wiring.
• All input and output cables, regardless of wire size
or number of wires, should consist of stranded,
insulated, and twisted copper wires.
• Shielded cable is not required for input or output
cables.
• Shielded cable is recommended for input and
output cables that are exposed to high
electromagnetic or radio frequency noise.
• Inputs/outputs with cables less than 30 m (100 ft)
typically do not require an offset in the software
setup. Cable runs over 30 m (100 ft) may require
an offset in the input/output software setup.
