Wiring

Risk of Electric Shock: Disconnect or isolate all power

supplies before making electrical connections. More than one disconnection 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.

Terminal Blocks and Bus Ports

See Figure 3 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 Table 3 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 controller and the other controllers in a daisy-chain configuration using 3-wire twisted, shielded cable as shown in the FC Bus Terminal Block wiring figure below. See Table 5 for more information.

Figure 4: FC Bus Terminal Block Wiring

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).

When connecting the IOM 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. See Input

and Output Wiring Guidelines for more information.

Figure 5: SA Bus Terminal Block Wiring

Note: The SA PWR/SHLD terminal does not supply 15

VDC. The SA PWR/SHLD terminal is isolated and can be used to connect (daisy chain) the 15 VDC power leads on the SA bus (Figure 5) or the cable shields on the FC bus (Figure 4). The SA bus supervisor (FAC, FEC, or VMA) supplies 15 VDC to devices on the SA Bus requiring power.

Supply Power Terminal Block

The 24 VAC supply power terminal block is a gray, removable, 3-terminal plug that fits into a board-mounted jack on the top right of the controller.

Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the terminal plug as shown in the following figure. The middle terminal on the supply power terminal block is not used. See Table 5 for more information about the Supply Terminal Block.

Figure 7: 24 VAC Supply Power Terminal Block Wiring

SA/FC Bus Port

The SA/FC bus port on the front of the controller is an RJ-12, 6-position modular jack that provides a connection for devices on the SA bus.

The SA/FC bus port is connected internally to the SA/FC bus terminal block. See Table 5 for more information. The SA/FC Bus Port pin assignment is shown in the Pin Number Assignments figure below.

Figure 6: Pin Number Assignments for Sensor, SA

Bus and FC Bus Ports on Controllers

Important: Connect 24 VAC supply power to the

controller and all other network devices so that transformer phasing is uniform across the network devices. Powering network devices with uniform 24 VAC supply power phasing reduces noise, interference, and ground loop problems. The controller does not require an earth ground connection.

Wireless Network Applications

Important: Wireless operation is not approved for

smoke control applications. Refer to the
