Cables wiring and positioning
The passage of the connecting cables must be prepared trying to
separate the electric supply cables from the signal cables using the
appropriate clamps. This image shows an example of a possible
cable layout and their passage through the cable seals and cable
glands included in the supply. For different cases use special
insulating sheaths.
* NOTE: for installation, see page 9.
