7.1.2 Saving setting on memory card
We recommend that you insert the memory card before switching on the inverter. The inverter
always also backs up its settings on an inserted card.
If you wish to back up the inverter settings on a memory card, you have two options:
Automatically backing up
Preconditions
● The inverter power supply has been switched off.
● No USB cable is inserted in the inverter.
Procedure
Proceed as follows to automatically back up your set‐
tings:
1. Insert an empty memory card into the inverter.
2. Switch on the operating voltage of the inverter.
After the power supply has been switched on, the inverter copies its changed settings to the
memory card.
Note
Accidental damage to the inverter firmware
If the memory card contains inverter firmware, the inverter may perform an operating system
update the next time the supply voltage is switched on. If you switch off the supply voltage
during the operating system update, the inverter firmware may be incompletely loaded and
damaged. The inverter cannot be operated with corrupt firmware.
● Before inserting the memory card, ascertain whether it also contains inverter firmware.
● Do not switch off inverter supply voltage during an operating system update.
Firmware upgrade and downgrade (Page 426)
Note
Accidental overwrite of the inverter settings
When the supply voltage is switched on, the inverter automatically accepts the settings already
backed up on the memory card. If you use a memory card on which settings are already backed
up, you will overwrite the settings of the inverter.
● To automatically backup your settings, use only a memory card that does not contain any
other settings.
