Important:
Do not connect supply power to the controller before finishing wiring and
checking all wiring connections. Short circuits or improperly connected wires can result in
damage to the controller and void any warranty.
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, or SA Bus, refer to the

PC Series Controllers MS/TP Communications Bus Technical Bulletin (LIT-12011670)
.
FX-PCV terminals and bus ports
for input and output terminal and bus port locations on the FX-
PCV1615/1626/1628/1630 controllers. Observe the following guidelines when wiring an FX-PCV
controller.
Input and Output terminals
The input spade terminals are located on the side of the FX-PCV near the terminal block. The output
spade terminals are located on the opposite side of the controller near the power supply terminal
block. See Table 3 for more information.
FC bus terminal block (Or N2 protocol as required)
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 FX-PCV and other controllers in a daisy-
chain configuration using 3-wire twisted, shielded cable as shown in Figure 3. See Table 5 for more
information.
Figure 3: FC bus terminal block wiring
Note:
The Shield terminal (SHLD) on the FC Bus terminal block is isolated and can be used to
connect the cable shields on the bus (Figure 3).
