Before commissioning after longer storage periods, measure insulation
resistance. In case of values ≤ 1kΩ per volt of rated voltage, dry winding.
For trial run without output elements, lock the featherkey. Do not deactivate
the protective devices, not even in a trial run.
Check the correct operation of the brake before commissioning low-voltage
machines with brakes.
Integrated thermal detectors do not provide full protection for the machine.
If necessary, limit the maximum current. Parameterise the controller so that
the motor will be switched off with I > I
r
after a few seconds of operation,
especially at the risk of blocking.
Vibrationalseveritiesv
eff
≤ 3.5 mm/s(P
r
≤ 15 kW)or4.5 mm/s(P
r
>15kW)are
acceptable if the clutch is activated.
If deviations from normal operation occur, e.g. increased temperatures,
noises, vibrations, find the cause and, if required, c ontact the manufacturer.
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 bearingswith relubricating devices while the low-voltage machine
is running. 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!
