4. Hold the expansion module in place, and insert
the screws through the mounting clips and into
the holes (or anchors). Carefully tighten all of
the screws.
Important: Do not overtighten the mounting
screws. Overtightening the screws may
damage the mounting clips.
Wiring
Warning
Risk of Electric Shock:
Disconnect or isolate all power supplies before mak-
ing electrical connections. More than one disconnec-
tion or isolation may be required to completely de-en-
ergize 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 iso-
lations et débranchements sont peut-être néces-
saires pour -couper entièrement l'alimentation de
l'équipement. Tout contact avec des composants con-
ducteurs de tensions dangereuses risque d'entraîner
une décharge électrique et de provoquer des
blessures graves, voire mortelles.
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
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 for-
mant un court-circuit ou connectés de façon incor-
recte risquent d'endommager irrémédiablement
l'équipement.
Important: Do not exceed the expansion
module electrical ratings. Exceeding expansion
module electrical ratings can result in
permanent damage to the expansion modules
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
expansion module components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid
damaging the expansion module.
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 Figure 1 for terminal block and bus port
locations on the expansion module. Observe the
following guidelines when wiring an expansion
module.
Input and output terminal blocks
The input terminal blocks are mounted on
the bottom of the expansion module and the
output terminal blocks are mounted on the
top of the expansion module. See Table 2 for
more 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 expansion module,
and the other controllers and expansion modules
