Wiring
CAUTION: Risk of Electric Shock.
! Disconnect the power supply before
making electrical connections to avoid
electric shock.
Mise En Garde: Risque de décharge
électrique: Débrancher l'alimentation
avant de réaliser tout raccordement
électrique afin d'éviter tout risque de
décharge électrique.

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
controller components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the controller.
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 FEC16 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.
