Preparations for use
Good planning and preparation of machine applications are essential in terms of keeping
installation simple and avoiding errors, ensuring safe operation, and allowing access to the
machine for servicing and corrective maintenance.
This chapter outlines what you need to consider when configuring your plant in relation to this
machine and the preparations you need to make before the machine is delivered.
Safety-related aspects to consider when configuring the plant
A number of residual risks are associated with the machine. These are described in the chapter
titled "Safety information" (Page 15) and in related sections.
Take appropriate safety precautions (covers, barriers, markings, etc.) to ensure the machine
is operated safely within your plant.
Observing the operating mode
Observe the machine's operating mode. Use a suitable control system to prevent overspeeds,
thus protecting the machine from damage.
Ensure that the machine is sufficiently cooled by the cooling air flow at the installation site:
● Ensure that the cooling air can flow in and out unobstructed. The full air flow provided by
● Make sure that the machine does not draw in the hot discharged air again.
● For machines with a vertical type construction with an air intake from above, ensure that
Thermal motor protection
The machine is equipped with PTC thermistors for direct monitoring of the motor temperature
to protect the machine against overheating during operation. Plan a corresponding circuit for

the fan is only possible if air can freely enter the impeller. In the axial direction, ensure a
clearance of at least 1 x air intake diameter.
the air inlets are protected against the ingress of foreign bodies and water.
