Replacing The Control Module - Siemens SINAMICS G110M Operating Instructions Manual

8.2

Replacing the Control Module

After commissioning has been completed, we recommend that you back up your settings on
an external storage medium, e.g.: on a memory card or the operator panel.
If you do not back up your data, you have to recommission the drive when you replace the
Control Unit.
Procedure for replacing a Control Module (CM)
Dangerous voltages!
Hazardous voltages are still present for up to 5 minutes after the power supply has been
switched off. Do not carry out any installation or replacement work before this time has
expired.
No Hot-swap of components
The components of the SINAMICS G110M system cannot be swapped, installed or
removed without securing any loads controlled by the application, removing the power
supply from the system and waiting 5 minutes to allow the electrical components of the
system to fully discharge.
Electrostatic discharge
Static discharges on surfaces or interfaces (e.g. terminal or connector pins) can cause
malfunctions or defects. ESD protective measures should therefore be observed when
working with converters or converter components.
Removing the Control Module
1. Disconnect all power supplies from the terminal housing.
2. Wait 5 minutes to allow all residual voltages and currents to dissipate.
3. Remove the Power Module (PM). See
4. Remove the Communications and Power Interface (CPI) ribbon cable from the Control
Module (CM).
5. Remove the PROFIBUS/PROFINET communications cable from the CM.
6. Undo the four CM self-retaining screws.
7. Remove the CM.
Replacing the Control Module
1. Fit the new CM.
2. Secure the CM in place using the four self-retaining screws.
3. Reconnect the PROFIBUS/PROFINET communications cable to the CM.
