Long-term storage
Connect the FI and the 24V modules to the mains voltage for 60 minutes at
the latest after one year.
Connect the FI and all other modules to be supplied with 24V to the 24V
control voltage for 60 minutes at the latest after one year.
Maintain this cycle throughout the storage period.
Protection class
