Saving settings to the memory card
We recommend that you insert the memory card before switching on the converter for the
first time. If a memory card is inserted, the converter saves every modified parameter value
on the card.
The memory card reader is located at the rear of the Control Unit. You have to insert the
card before the Control Unit is fitted to the Power Module.

Upload
Procedure
Proceed as follows to transfer the parameter setting from the converter on to a memory card
(upload):
1.
Switch off the converter power supply.
2.
Remove the Control Unit from the Power Module.
3.
Insert an empty memory card into the Control Unit.
Note
If the memory card is not empty and already contains parameter settings, the converter
will take the parameter settings from the memory card. The previous setting in the
converter will be deleted.
4.
Fit the Control Unit to the Power Module - making sure that the seals are fitted correctly
and the correct tighten torque (2.0 Nm) is used to ensure the IP rating of the converter.
5.
Connect the external 24 V supply to the Control Unit.
After the Control Unit has been powered-up, the converter copies all modified parameters to
the memory card.
