Wiring rules
The wires (terminals 1 and 5, 4 and 8) must be in twisted pairs and shielded. The shield
must be supported at both ends. You use the shield contact element
(Order Number: 6ES7 390-5AA00-0AA0) as a shield support.

Connection of Relays and Contactors to the Digital Output
Note
Direct connection of inductivities (such as relays and contactors) is possible without external
circuiting.
If SIMATIC output circuits can be deactivated by additionally installed contacts (for example
relay contacts), you have to provide additional overvoltage protection devices at inductivities
(see the following example for overvoltage protection).
