•
Additional devices which are present (e.g. brakes) are functional,
•
The coolant supply is not restricted,
•
Measures have been taken to protect against contact with moving and live parts.
4 Maintenance
Danger
Installations and work may only be carried out with the device
deenergised (separated from the mains) and the motor shut down.
Death, cardiac arrhythmia
► Observe the 5 safety rules, see chapter List of safety and installation
notes on page 5
4.1 Inspection
Depending on the level of the contamination, the entire surfaces of the motors should be cleaned.
In most cases, the first inspection should be carried out after approx. 500 operating hours, after 1 year
at the latest. Follow-up inspections should be carried out within appropriate intervals based on
application conditions, for instance re-lubrication or re-greasing, however at least once a year.
Accumulating dust should also be removed every now and then.
During inspection, it should be checked whether
•
the technical data is observed in accordance with the rating plate,
•
there are no leaks (oil, grease, water),
•
the operating noises of the bearings as well as the smooth running of the motor have not
deteriorated,
•
all mounting screws for electrical and mechanical connections are tight,
•
the connection of cable screws on the terminal box is fixed properly. If the cable screws are loose,
the strain relief (if present) should be loosened and then, the cable screw should be tightened until
the cable can no longer move. Tightening the cable screw too firmly will cause constrictions in the
cable and should absolutely be prevented. After successful tightening, the strain relief (if present)
should be refastened.
•
the alignment of the motor is within the approved tolerances during coupling operation.
•
any accumulated dust is removed.
4.2 Bearings
4.2.1 Bearings with permanent lubrication
The motor bearings with permanent lubrication are maintenance-free under normal operating
conditions for 10000 to 20000 operating hours, but not longer than 3 years.
4.2.2 Bearings with re-lubrication
For motors with a re-lubrication device, the re-lubrication interval, grease quantity and grease quality
are specified on an additional label on the motor.
The prescribed lubrication intervals are shorter under extreme loads and/or at increased temperatures.
If the number of operating hours specified on the lubrication plate is not reached within 3 years, then
re-lubrication should be carried out early. Re-lubrication should be done with the shaft turning.
Lubricants see page 11.
After approx. 15000 operating hours, or 3 years at the longest, the grease should be replaced owing to
ageing and excessive lubrication of the bearings. Here, inspect the bearings and replace if necessary.
Mixing of different grease types must be avoided!
