5.2 Preparing for installation
Material damage caused by improper handling
Mounting parts such as temperature sensors or speed sensors are attached to the machine and
could be ripped off or destroyed as a result of improper handling. This could lead to machine
malfunctions, extending even to total loss of the machine.
• Use suitable steps when carrying out installation work on the machine.
• Do not stand on cables or attachments during installation. Do not use attachments as steps.

Preparing for installation
Note
Note also the technical data on the rating plates on the motor enclosure.
NOTICE
Damage to the motor
To avoid material damage, before commissioning, check whether the correct direction of
rotation of the machine has been set on the customer side, e.g. by decoupling from the driven
load.
5.2.1
Requirements for installation
The following requirements must be satisfied prior to starting installation work:
• Staff have access to the operating and installation instructions.
• The machine is unpacked and ready for mounting at the installation location.
• Measure the insulation resistance of the winding before starting any installation work. If the
insulation resistance lies below the specified value, take appropriate remedial measures.
These remedial measures may necessitate the machine being removed again and
transported.
Damage to mounted parts and components as a result of high temperatures
The motor components get very hot during operation. High temperatures can damage parts
mounted by customers, such as cables manufactured out of materials that are not heat resistant.
• Temperature-sensitive parts must not come into contact with or be attached to components
mounted on the machine.
• Only use heat-resistant mounting parts. The connecting cables and cable entries must be
suitable for the particular application.
