DANGER
During assembly, cleaning, maintenance and commissioning when
close to live components, an electric shock can cause serious
injury or death.
► All work must be carried out only by trained personnel and when
no power is applied!
► Verify that the parts are deenergized by means of a voltmeter!
► The vertical axis has to be free of load!
The motor gear box is self-lubricating and maintenance-free!
Observe the contamination of the enclosure – strong contamination on
the outside can increase the operating temperature of the drive unit!
Therefore, clean the drive unit from time to time (with a vacuum cleaner
etc.). If the drive unit gearbox has to be changed for any reason, the
complete unit has to be replaced!
