Safety
EMC:
If a product is modified in any manner not agreed with us in advance, this de-
claration becomes void.
When using the sensor with an extension care must be taken to ensure that
wiring is not laid alongside or close to high-voltage power cables and that it is if
necessary properly shielded so as to prevent spurious interference being in-
duced in the system.
