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 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 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 encoder can cause short circuits and damage the optical sensing sys-
tem.
• Absolute cleanliness must be maintained when carrying out any work on the open terminal box.
• When dismantling, never allow lubricants to penetrate the encoder.
3.6
Risk of destruction due to adhesive fluids
Adhesive fluids can damage the optical sensing system and the bearings. Dismounting an en-
coder, secured to a shaft by adhesive may lead to the destruction of the unit.
3.7
Explosion risk
You can use the encoder in areas with explosive atmospheres of category 3 D and 3 G except for
the version with earthing brush or with internal heating which must not be used in potentionally
explosive atmospheres. The operation in other explosive atmospheres is not permissible.
