5.1 LOCK switch/power failure
All coniguration parameters are iled in a non-volatile storage medium (EAROM). There is
an additional write protection (LOCK switch).
If the grid power fails, all entered parameters are saved.
In general we recommend that after coniguration, you set the switch to the closed
position to prevent accidental overwriting of the parameters.
For legal-for-trade applications, the LOCK switch must be sealed in the closed position.
