Electric shock when connecting a PROFIBUS cable under voltage
When connecting the PROFIBUS cable while voltage is present, there is a danger of
coming into contact with live components behind the terminal.
Touching live components can result in death or serious injury.
• Only connect the PROFIBUS cable to connector X126 when the device is in a no-

Basic information about EMC

What is EMC?
EMC stands for "electromagnetic compatibility" and describes "the capability of a device to
function satisfactorily in an electromagnetic environment without itself causing interference
unacceptable for other devices in the environment". Therefore, the various devices used
should not cause interference to one another.
Within the context of the EMC Directive, the SINAMICS DC MASTER devices described in
this document are not "devices" at all, but are instead "components" that are intended to be
installed in an overall system or overall plant. For reasons of clarity, however, the generic
term "devices" is used in many cases.
