ATTENTION
Risque de décharge électrique
Débrancher l'alimentation avant de réaliser tout rac-
cordement électrique afin d'éviter tout risque de
décharge électrique.
CAUTION
Risk of Property Damage
Do not apply power to the system before checking all
wiring connections. Short circuited or improperly con-
nected wires may result in permanent damage to the
equipment.
ATTENTION
Risque de dégâts matériels
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils for-
mant un court-circuit ou connectés de façon incor-
recte risquent d'endommager irrémédiablement
l'équipement.
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, FC bus, and SA bus, refer to the
MS/TP
Communications Bus Technical Bulletin (LIT-12011034).

detailed information on wiring an N2 network, refer to the
N2 Communications Bus Technical Bulletin (LIT-636018)

FAC terminal blocks and bus ports
See Figure 1 for terminal block and bus port locations on
the FAC2611 controller. Observe the following guidelines
when wiring a controller.
Input and Output terminal blocks
On most field controller models, all of the fixed input
terminal blocks are mounted on the bottom of the
controller, and the output terminal blocks are mounted on
the top of the controller. See Table 2 for more information
about I/O terminal functions, requirements, and ratings.
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 controller, and other controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 4. For more information about the FC
Bus terminal function, requirements, and ratings, see
Communications bus and power supply terminal block
.
Figure 4: FC bus terminal block wiring
Note:
The FC bus Shield (SHLD) terminal is isolated
and can be used to connect (daisy chain) the shields
for FC bus wiring.
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
controller, and other SA bus devices in a daisy-chain
configuration using 4-wire twisted, shielded cable as
shown in Figure 5. For more information about the SA Bus
terminal function, requirements, and ratings, see
FAC2611 Advanced Application Field Equipment Controller Installation Guide
