Cautions during Installation

• Install the unit correctly with the usage environment, location, and the designated

specifications.

• Do not load overweight on the shaft.

• Do not put strong impact when insert a coupling into shaft.

Failure to follow this instruction may result in product damage.

• When fixing the product or coupling with a wrench, tighten under 0.15 N m.

• If the coupling error (parallel misalignment, angular misalignment) between the shaft

increases while installation, the life cycle of the coupling and the encoder can be

shorten.

• Do not apply tensile strength over 30 N to the cable.

Ordering Information

This is only for reference, the actual prodcut does not support all combinations.
