Preparations for use
4
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 15) 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 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
monitoring.

4.4 Interlock circuit for anti-condensation heating (option)
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
machine is switched on.
● Only switch on the anti-condensation heating after the motor has been switched off.
Carefully comply with the data on the anti-condensation heating plate.
