Wiring

Risk of Electric Shock:

Disconnect or isolate all power

supplies before making electrical connections. More than
one disconnect or isolation may be required to
completely de-energize equipment. Contact with
components carrying hazardous voltage can cause
electric shock and may result in severe personal injury
or death.

Avertissement: Risque de décharge électrique

:

Débrancher ou isoler toute alimentation avant de réaliser
un branchement électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires pour
-couper entièrement l'alimentation de l'équipement. Tout
contact avec des composants conducteurs de tensions
dangereuses risque d'entraîner une décharge électrique
et de provoquer des blessures graves, voire mortelles.

Risk of Property Damage:

Do not apply power to the

system before checking all wiring connections. Short
circuited or improperly connected wires may result in
permanent damage to the equipment.

Mise En Garde: Risque de dégâts matériels:

Ne pas

mettre le système sous tension avant d'avoir vérifié tous
les raccords de câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte 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

FX-PC

Series Controllers MS/TP Communications Bus Technical
Bulletin (LIT-12011670)

.

Terminal Blocks and Bus Ports

See

Figure 3

for terminal block and bus port locations on

the FX-PCX controller. Observe the following guidelines
when wiring an FX-PCX controller.

Input and Output Terminal Blocks

All of the 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 3

for more

information about I/O terminal functions, requirements,
and ratings.

SA/FC Bus Terminal Block

An FX-PCX can be connected to a Sensor/Actuator (SA)
bus or a Field Controller (FC) bus, but not to both buses
simultaneously. The SA/FC bus terminal block is a
removable, 4-terminal plug that fits into a board-mounted
jack.

When connecting the FX-PCX to an FC bus, wire the bus
terminal block plugs on the controller, and the other
controllers in a daisy-chain configuration using 3-wire
twisted, shielded cable as shown in

Figure 4

. See

Table

5

for more information.

When connecting the FX-PCX to an SA bus, wire the 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
