Wiring
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.
WARNING
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.
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 rat-
ings. 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 dis-
charge 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 Figure 1 for terminal block and bus port
locations on the controller. Observe the following
guidelines when wiring a controller.

Input and Output terminal blocks

Most 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
IOM1711 and IOM2711 Input/Output Module Installation Guide
