Long-term storage Connect the frequency inverter to the mains voltage for 60 minutes at the latest
after one year. Maintain this cycle throughout the storage period.
Protection class IP20
Max. mounting altitude above sea
level
up to 1000m: No power reduction
1000...4000m: 1%/ 100m power reduction (up to 2000m overvoltage cat. 3)
