Replacing the Power Module

Procedure for replacing a Power Module
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 Power Module
1. Disconnect all external power to the system; this includes the line supply and the 24 Vdc
supply to the Control Module (CM).
2. Wait 5 minutes to allow all residual voltages and currents to dissipate.
3. Undo the Power Module's (PM) four self-retaining screws.
4. Remove the PM from the Terminal Housing.
5. Remove the memory card from the memory card reader (if one is fitted).
Replacing the Power Module
1. Insert the memory card in the new PM.
2. Fit the PM onto the Terminal Housing.
3. Fasten the four self-retaining screws (ensuring the are tightened to the correct torque).
4. Reconnect the mains supply and the external 24 V supply to the system.
5. The CM will automatically read the default parameter set that is stored on the memory
card.
6. The converter will then go into the "ready-to-switch-on" state.
7. If you have not backed up your settings, then you must recommission the drive.
