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.
4.1

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 13) and in related sections.
Take appropriate safety precautions (covers, barriers, markings, etc.) to ensure the machine
is operated safely within your plant.
4.2

Observing the operating mode

Observe the machine's operating mode. Use a suitable control system to prevent overspeeds,
thus protecting the machine from damage.
4.3

Ensure adequate cooling

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

Interlock circuit for anti-condensation heating

If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine.
● Install an interlock circuit that switches off the anti-condensation heating once the main
● Only switch on the anti-condensation heating after the machine has been switched off.
