Wiring
Observe the following guideline when wiring a controller:
For information on the MS/TP Bus, refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) .
To install the FEU26, see
Hard-Wired Installation
.
Hard-Wired Installation
To install an FEU26 for hard-wired operation, perform the steps that follow. See
Figure 1
for jack and terminal block
locations.
Input/Output Terminals
Terminate Input/Output (I/O) point wiring at the controller per engineering drawings. See
Table 2
for more I/O wiring
information.
SA Bus Terminal Block and Sensor Port
Wire Network Sensors and other devices to the Sensor Actuator (SA) Bus terminal block (
Figure 6
) or Sensor port
(RJ-12 modular jack) for sensors.
Note: The FEU26 should be at one end of the SA Bus daisy chain. If multiple Input/Output Modules (IOMs) are
used, set the End-of-Line (EOL) switch on the last IOM.
FC Bus Terminal Block
Wire the Field Controller (FC) Bus in a daisy chain to other devices on the FC Bus and the supervisory controller.
See
Figure 7
to terminate the wires.
Note: The Shield terminal (SHLD) on the FC Bus terminal block is isolated and can be used as a convenient
terminal for connecting the bus cable shield (if shielded cable is used on the bus).
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.
