Efficiency of frequency inverter
Approx. 95 %
Ambient temperature
-10°C ... +50°C (without condensation)
Storage/Transport temperature
-20°C ... +60°C / +70°C, (max. 85% without condensation)
Long-term storage
Connect the frequency inverter to the mains voltage for 60 minutes at least
once a year. Maintain this cycle throughout the storage period.
Protection type
IP55 / IP66 (option), dependent on motor used
Galvanic isolation
Control terminals (digital inputs / outputs)
Max. mounting height above zero
Up to 1000m: No power reduction
1000...4000m: 1%/ 100m power reduction
(up to 2000m overvoltage category 3)
2000...4000m: Only overvoltage category 2 is maintained, external
overvoltage protection at the mains input is necessary
Wait time between two mains switch on
cycles
60 sec for all devices in normal operating cycle
Supply voltage 15V/5V
