Wiring
Observe the following guidelines when wiring a controller:
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.
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.

the controller. Observe the following guidelines when
wiring a 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
information about I/O terminal functions, requirements,
and ratings.

SA/FC Bus Terminal Block

An IOM 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 IOM 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
5 for more information.
