Commissioning and operation
Before commissioning after longer storage periods, measure insulation resistance. In case

For trial run without output elements, lock the featherkey. Do not deactivate off the
protective devices, not even in a trial run.
Check the correct operation of the brake before commissioning low-voltage machines
with brakes.
Integrated ther mal detectors do not provide full protection for the machine. If necessary,
limitthe maximum current. Parameterisethe controllerso thatthe motor will be switched

If deviations from normal operation occur, e.g. increased temperatures, noises, vibrations,
find the cause and, if required, contact the manufacture r. In case of doubt, switch off the
low-voltage machine.
If the machine is exposed to dirt, clean the air channels regularly.
Shaft sealing rings and roller bearings have a limited service life.
Regrease bearings with relubricating devices while the low-voltage machine is r unning.
Only use the grease recommended by the manufacturer. If the grease drain holes are
sealed with a plug, (IP54 drive end; IP23 drive and non-drive end), remove plug before
commissioning. Seal bore holes with grease. Replace prelubricated bearings (2Z bearing)
after approx. 10,000 h - 20,000 h, at the latest however after 3 - 4 years.
The product-specific safety and application notes given in these Instructions must be
observed!
2.2 General safety and application notes for Lenze controllers
(to: Low-Voltage Directive 73/23/EEC)
General
Lenze controllers (frequency inverters, servo inverters, DC speed controllers) and the
accessory components can include live and rotating par ts - depending on their type of
protection - dur i ng operation. Surfaces can be hot.
Non-authorised removal of the required cover, inappropriate use, incorrect installation or
operation, create the risk of severe injury to persons or damage to mater ial assets.
More information can be obtained from the documentation.
All operations concerning transport, installation, and commissioning as well as
maintenance must be carried out by qualified, skilled personnel (IEC 364 and
CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110 and national
regulations for the prevention of accidents must be observed).
According to this basic safety information, qualified, skilled personnel are persons who are
familiar with the assembly, installation, commissioning, and operation of the product and
who have the qualifications necessary for their occupation.
