7.1.1
General instructions
Clean wherever and whenever the degree of contamination makes it necessary in order
to ensure that the waste heat is adequately dissipated. As the operating conditions vary
greatly, one can only cite general intervals for fault-free operation.
Guidelines:
- Bearing service life 20,000 hours
- Radial shaft seals approx. 5,000 hours with oil lubrication
The motors' rotors contain permanent magnets with high magnetic flux densities
which exert strong attractive forces on ferromagnetic bodies.
People fitted with a heart pacemaker are at risk in the vicinity of a disassembled
rotor. Data stored on electronic data media may be destroyed.
The encoder system must be readjusted each time after the motor has been
disassembled.
The maintenance of the geared motors is kept to a minimum by their design
concept (see Chapter 7.1.2 "Lubrication").
All components subject to operational wear (for example friction linings of brakes)
must be included in the regular maintenance measures.
SIEMENS service partners are available for all maintenance work on gears (see Chapter
6 "Instructions in case of faults").
Safety rules for working in electrical installations as per
EN 50110-1 (DIN VDE 0105-100):
- Work always with the equipment electrically dead.
- Isolate from electrical supply.
- Secure against switching on again.
- Check electrical deadness.
- Earth and short-circuit.
- Cover or cordon off adjacent parts which are electrically live.
- Release for work.
- Connect the PE conductor to
30
ENGLISH
Electric shock hazard!
When the rotor is rotating, the motor terminals carry a dangerous
voltage.
Stop the motor before commencing any electrical work.
Only use trained, qualified personnel for assembly work on the
converters and plugs.
Observe the regulations for working in electrotechnical plants.
