8.2 Replacing the 3RW5 communication module
SIRIUS 3RW5 Modbus TCP communication module

Replacing the 3RW5 communication module
Communication parameters are stored in the 3RW5 communication module and not
automatically transferred into the replacement device.
Observe the following chapters on the communication parameters:
● Configuring the 3RW5 Soft Starter (Page 41)
● Communication parameters (Page 99)
Note
Backing up communication parameters on micro SD memory card
Depending on the 3RW5
soft starter, you can back up the communication parameters to a
micro SD memory card via the 3RW5
HMI High Feature.
You will find more information on backing up the configuration data to a micro SD memory
card and on operating the 3RW5 HMI High Feature in the Manual of the 3RW5 soft starter.
Damage to property due to electrical voltage
Switch off the power to the 3RW5 soft starter before starting work (main and control supply
voltage).
1. Remove the bus connector. (Page 37)
2. Remove the 3RW5 communication module. (Page 33)
3. Mount the 3RW5 communication module. (Page 32)
4. Connect the 3RW5 communication module to the bus connection. (Page 35)
You have replaced the 3RW5 communication module and can commission the 3RW5 soft
starter in the bus connection.
Set the communication parameters anew. If you backed up the communication parameters
to a micro SD memory card before replacement, you can transfer them from the micro SD
memory card to the replacement device.
