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
Cooling water quality for water-cooled motors
The values specified for the cooling water correspond to the requirements for a closed cooling
circuit. Not all of the specified concentrations will occur in the cooling water at the same time.
A filter can be used to ensure smooth operation; the grade of filtration should not exceed
100 μm.
