● Before installing the firmware update, make sure that the modules are not being used.
NOTICE
Firmware update for fail-safe motor starters
In the case of fail-safe motor starters, the firmware update is permissible only if the
motor starter is the only module on a rack.
Make sure before a firmware downgrade of fail-safe motor starters with a F-
DI BaseUnit (MS5-MS10) that the associated F-DI is on 1-signal (=value of "1").
Also make sure that the motor starter is only connected to the device on which the firmware
is being updated (e.g. PG/PC or CPU).
NOTICE
Loss of the safety function after an incorrect firmware update
The safety functions can be lost if you inadvertently install a firmware update on a motor
starter for which the update was not intended.
Make sure that the PG/PC or the CPU is exclusively connected to the motor starter on
which the firmware is being updated.
