The electric machine

The electric machines have several frame models (sizes) to be the optimal solutions for several
applications.  They also have options for shaft type, attachment interface, bearings, connection box
attachment, rotation sensors and temperature sensors.

Intended use of the electric machine

This electric machine is intended to be used as a motor or generator and as a part of a machinery, for
example in:

Power train of a marine vessel, transportation vehicle or a heavy duty work machine.

Power generation equipment.

The electric machine is intended to be powered and controlled with an inverter or inverters capable of
supplying three-phase alternating current and that is capable of controlling the electric machine. The
electric machine is not suitable for direct online use.

In a power generation equipment the electric machines are intended to be powered by a prime mover,
for example, an internal combustion engine and controlled by the above mentioned electric power
inverter.

The electric machine is solely intended for professional use, and may be operated only by trained
professionals. The maintenance of the electric machine may be done only by trained professionals.

Forbidden use of the electric machine

It is forbidden to use, handle and maintain the machine in following ways (including but not limited to):

Using the electric machine for other purposes than defined in this user guide.

Disregarding the obligation to comply with the user guide, safety signs and rating plate of the electric
machine.

Using the electric machine, making adjustments and maintenance without first reading this user
guide.
