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.
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)
.
Terminal Blocks and Bus Ports
See
for terminal block and bus port locations on
the controller. Observe the following guidelines when
wiring a controller.
Input and Output Terminal Blocks
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 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 below. See
for more information.
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 the following figure. See
for more
information.
