Danger due to induced voltages
Electrical voltages are induced in the stator when rotating the rotor. Touching the stator
connections can result in death or severe physical injury.
● Before starting any work at the machine, carefully ensure that the system is secured to
● If you must rotate the rotor, then ensure that each phase is grounded.

Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
● Only touch electronic modules if you absolutely have to work on them.
● The body of the person concerned must have been electrostatically discharged and
● Electronic modules should not be brought into contact with electrically insulating materials,
● Always place electrostatic sensitive devices on conductive bases.
● Always pack, store and transport electronic modules or components in conductive
