NOTE
Terminals are not all located on the same PCB.
Very long control cables and analogue signals may in rare
cases and depending on installation result in 50/60 Hz
earth loops due to noise from mains supply cables.
If this occurs, it may be necessary to break the screen or
insert a 100 nF capacitor between screen and chassis.

NOTE
To comply with EMC emission specifications, screened
cables are recommended. If an unscreened cable is used,
see
4.5.15 Unscreened Control Wires
. If unscreened control
cables are used, it is recommended to use ferrite cores to
improve EMC performance.
