Figure 3.12 Typical Wiring Diagram for Two-Wire Control with Stopping
Control (No DPI Control)
➀
Customer supplied.
➁ Refer to the controller nameplate to verify the rating of the control power input voltage.
For units rated 625…1250 A, terminals 11 & 12 are factory pre-wired from terminal block
CP1 - terminals 1 & 4.
Notes: (1) Programmable controller interfacing in this diagram refers to hard-wiring between the
PLC’s output contacts and the SMC-Flex controller’s control terminals.
(2) The OFF state leakage current for a solid-state device must be less than 6 mA.
