Security indications
3.1 Risk of injury due to rotating shafts
Hair and clothes may become tangled in rotating shafts.
•
Before all work switch off all operating voltages and ensure machinery is stationary.
3.2 Risk of destruction due to electrostatic charge
Electronic parts contained in the absolute encoder are sensitive to high voltages.
•
Do not touch plug contacts or electronic components.
•
Protect output terminals against external voltages.
•
Do not exceed max. operating voltage.
3.3 Risk of destruction due to mechanical overload
Rigid mounting may give rise to constraining forces.
•
Never restrict the freedom of movement of the absolute encoder. The installation instructions
must be followed.
•
It is essential that the specified clearances and/or angles are observed.
3.4 Risk of destruction due to mechanical shock
Violent shocks, e. g. due to hammer impacts, can lead to the destruction of the optical sensing system.
•
Never use force. Assembly is simple when correct procedure is followed.
•
Use suitable puller for disassembly.
3.5 Risk of destruction due to contamination
Dirt penetrating inside the absolute encoder can cause short circuits and damage the optical sens-
ing system.
•
Absolute cleanliness must be maintained when carrying out any work on the open absolute encoder.
•
When dismantling, never allow lubricants to penetrate the absolute encoder.
3.6 Risk of destruction due to adhesive fluids
Adhesive fluids can damage the optical sensing system and the bearings. Dismounting an abso-
lute encoder, secured to a shaft by adhesive may lead to the destruction of the unit.
3.7 Explosion risk
You can use the absolute encoder in areas with explosive atmospheres of category 3D and 3G.
The operation in other explosive atmospheres is not permissible.
