Safety information

Improper transport and installation of devices and components
Serious injury or even death and substantial material damage can occur if the devices are
not transported or installed properly.
• Transport, mount, and remove the devices and components only if you are qualified to

Messages after replacement of DRIVE-CLiQ components

After DRIVE-CLiQ components are replaced (Control Interface Module, TM31, SMCxx) when
service is required, generally no message is output after power-up, since an identical
component is identified and accepted as component when the system boots.
The reason for this is that an identical component is detected and accepted as spare part
when running-up. If, unexpectedly, a fault message of the "topology fault" category is
displayed, then when replacing a component, one of the following faults/errors should have
occurred:
• A Control Interface Module with different firmware data was installed.
• When connecting-up DRIVE-CLiQ cables, connections were interchanged.
Automatic firmware update
A firmware update for the replaced DRIVE-CLiQ component may run automatically after
switching on the electronics.
• The following LEDs will flash slowly to indicate that an automatic firmware update is in
progress: the "RDY" LED on the Control Unit (orange, 0.5 Hz) and an LED on the relevant
DRIVE-CLiQ component (green/red, 0.5 Hz).
Note
Do not shut down the converter
During this operation, the converter should not be shut down, as otherwise the firmware
update must be started again.
• Once the automatic firmware update is complete, the "RDY" LED on the Control Unit will
flash quickly (orange, 2 Hz) along with an LED on the relevant DRIVE-CLiQ component
(green/red, 2 Hz).
• To complete the automatic firmware update process, a POWER ON is required (switch the
device off and back on again).
