Even in the event of large differences in the ground potential, ground loops are effec‐
tively prevented. As a result, equalizing currents can no longer flow via the cable shields
and metal housing.
NOTICE
The voltage supply for the device and the connected peripheral devices must also
guarantee the required level of insulation.
Under certain circumstances, a tangible potential can develop between the insulated
metal housings and the local ground potential.

NOTICE
It is strongly recommended to use an encoder for measuring applications, such as
shape measuring and volume measuring. If no encoder is used, analysis results may be
inaccurate due to object traversing speed variations.
The encoder must fulfill the following requirements:
