Installation
Instruction:
a) Attach the coupling onto the encoder shaft according to the related mounting instructions.
b) When using the K 35 spring washer of Baumer Hübner, consider the maximum permitted
tolerances for mounting errors.
c) Fasten the coupling at the specified torque (K 35: Mt = 1 Nm (plastic side), Mt = 1.3 ± 10%
Nm (metal side)). Observe the remarks in the spring washer assembly instructions.

Mounting encoder onto drive shaft
DANGER
Injuries caused by shaft rotation
Hair and clothing may get caught in rotating shafts which may lead to serious personal injury.
a) Make sure the device is idle.
b) Before performing any work at the device, make sure power supply is and remains discon-
nected.
DANGER
Explosion
Sparks may cause fire or explosion.
a) Do not use the device in the near vicinity of explosive or highly flammable materials.
NOTICE
Equipment damage by mechanical overload
Mounting under tension may cause overload by constraining forces.
a) Observe the mounting instructions.
b) Observe the specified distances and/or angles.
NOTICE
Ball bearing damage caused by hard impacts on coupling
Hard shaft impacts imposed on parts of the coupling can damage the ball bearings and there-
fore are not permitted. If properly selected, the components can be easily assembled without
applying any axial pressure.
a) Otherwise, check and correct the dimensions and tolerances.
NOTICE
Severe runout errors of the drive shaft reduce service life and may cause angular errors.
Severe runout errors of the drive shaft cause vibrations that cut down on the encoder service
live and may cause angular errors.
a) Keep runout errors of drive shaft down to a minimum (recommended: ≤ 0.03 mm; maximum:
≤ 0.2 mm).
