Installation Chapter 2
• To meet produce susceptibility requirements, ferrite cores need to be
added to the communication lines. All cores specified below are the split
core type, so they can be added to existing connections.
– When using an external HIM (or DPI interface), a core should be
added to the HIM cable near the SMC Flex control module. The
recommended core is Fair-Rite no. 0431167281 or equivalent.
– When using DeviceNet, two cores need to be added to the DeviceNet
cable near the SMC Flex control module. The recommended cores are
TDK ZCAT2033 0930H and TDK ZCAT2035 0930 or equivalent.
Control Power Control Voltage
The SMC Flex controller will accept a control power input of 100 to 240V AC,
(-15 / +10%), 1 phase, 50/60 Hz. Refer to the product nameplate to verify the
control power input voltage.
Connect control power to the controller at terminals 11 and 12. The control
power requirement for the control module is 75 VA. Depending on the specific
application, additional control circuit transformer VA capacity may be required.
Control Wiring
Table 2 provides the control terminal wire capacity and the tightening torque
requirements. Each control terminal will accept a maximum of two wires.
