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
