Replacing A Converter With Enabled Safety Function - Siemens SINAMICS G120 Function Manual

Special issue relating to communication via PROFINET: Device replacement without removable data
storage medium
The inverter supports the PROFINET functionality, replacing the device without data storage
medium.
Precondition
The topology of the PROFINET IO system with the IO device involved is configured in your
higher-level control system.
Replacing the device
The inverter can be replaced without having to insert a removable data storage medium (e.g.
a memory card) with the saved device names in the inverter – or having to reassign the
device names with a PG.
Details of the device replacement without removable storage medium can be found in the
PROFINET system description

Replacing a converter with enabled safety function

Risk of fatal injury when touching energized Power Module connections
After the power supply has been switched off, it takes up to 5 min. until the capacitors in the
inverter have discharged so that the remaining voltage is at a non-hazardous level. Death
or serious injury can result when live parts are touched.
• Check that the inverter connections are in a no-voltage condition before you carry out
NOTICE
Material damage caused by interchanging the motor connecting cables
The direction in which the motor rotates changes if you interchange the two phases of the
motor cable. A motor running backwards may damage the machine or installation.
• Connect the three phases of the motor cables in the correct sequence.
• After replacing the Power Module, check the direction in which the motor rotates.
