General safety instructions
3.1
Risk of injury due to rotating shafts
Hair and clothes may become tangled in rotating shafts. Examine that involved
equipment can not be powered up during installation.
• Before all work switch off all operating voltages and ensure machinery is stationa-
ry.
• Secure machines of restarting.
3.2
Risk of destruction due to mechanical overload
• Never restrict the freedom of movement of the encoder. The installation instruc-
tions must be followed.
• Never use force. Assembly is simple when correct procedure is followed.
• Use suitable puller for disassembly.
• It is imperative to observe the specifications of the „Technical data“ of the relevant
data sheet.
3.3
Risk of destruction due to mechanical shock
Violent shocks, e. g. due to hammer impacts, can lead to the destruction of the
sensing system.
• The encoder keeping away from mechanical vibrations, which are above the
specifications of the data sheet (don‘t throw or drop the encoder).
• It is essential that the specified clearances and/or angles are observed.
• Use suitable puller for disassembly.
3.4
Risk of destruction due to adhesive fluids
Adhesive fluids can damage the optical sensing system and the bearings of the
encoder. Dismounting an encoder, secured to a shaft by adhesive may lead to the
destruction of the unit.
3.5
Risk of destruction due to soiling
Dirt penetrating inside the encoder can cause short circuits and damage the optical
sensing system.
• Absolute cleanliness must be maintained when carrying out any work on the
electrical connection.
• The encoder, in particular seals and connecting cables, may not come into
contact with corrosive liquids.
• When mounting/demounting, never allow oil, grease or other liquids to penetrate
the inside of the encoder.
3.6
Explosion risk
Do not use the encoder in areas with explosive and/or highly inflammable
materials. They may explode and/or catch fire by possible spark formation.
