Frequently Asked Questions

What kind of motor can I connect to this inverter?

You can connect standard three-phase asynchronous motors rated up to 550 horsepower.

Why is the mains current rating so high (713A)?

The high current rating is needed to start and control very large motors. It ensures reliable operation under heavy load.

Can it be used outdoors?

No. The IP20 rating means it is for dry, indoor environments only. It must be installed inside a protective control cabinet.

Is a cooling system required?

Yes. Due to its high power, adequate ventilation or cabinet cooling is essential to stay within the 0-50°C operating limit.

What is the main application for a drive of this size?

It is used in heavy industry for large compressors, centrifugal pumps, main conveyor drives, and large fan systems.
