Series 20
Series 40
Series 80

15. Generic rules : ground loop
Minimize ground loop areas : cables must be as close as possible from earthed metallic part
Series 20
Series 40
Series 80
A ground loop results from the area between an active conductor and the ground.

16. Generic rules : I/O Series 20 Series 40 Series 80
Outgoing and incoming I/O cables must be together
Series 20
Series 40
Series 80
Shielded cables are grounded at both ends
(only if both sides are equipotent by an other way !!!)
